Description:
RELATED APPLICATION 
     This application claims priority to U.S. Provisional Patent Application No. 62/945,718, which is entitled CUSTOMIZABLE PROBE CARDS, PROBE SYSTEMS INCLUDING THE SAME, AND RELATED METHODS, was filed on Dec. 9, 2019, and the complete disclosure of which is hereby incorporated by reference. 
    
    
     FIELD OF THE DISCLOSURE 
     The present disclosure relates generally to probe cards for probe systems and more specifically to customizable probe cards with probes configured to be selectively repositioned on the customizable probe cards. 
     BACKGROUND OF THE DISCLOSURE 
     Probe systems may be utilized to test the operation of a device under test (DUT). In specific examples, the DUT may include a semiconductor device, and the probe system may be configured to electrically test the operation of the DUT, such as by providing a test signal to the DUT and/or by receiving a resultant signal from the DUT. 
     In some configurations, the probe systems utilize a probe card that includes one or more probes for testing the DUT, with the probe card being configured to be selectively and repeatedly installed on and removed from a probe card holder of the probe system. In this manner, the probe systems may be reconfigured for testing differently configured DUTs by selectively installing a probe card with probes that are specifically configured and/or arranged for testing a given DUT. However, replacing the probe cards in this manner may incur undesired downtime and/or monetary expenses. In addition, each probe card may be custom-made for a given DUT, thereby increasing operational costs and/or lead time associated with designing, manufacturing, and/or obtaining an appropriate probe card for a given DUT. Thus, there exists a need for customizable probe cards. 
     SUMMARY OF THE DISCLOSURE 
     Customizable probe cards, probe systems including the same, and related methods are disclosed herein. A customizable probe card for testing one or more devices under test (DUTs) includes a support structure, one or more probe assemblies supporting respective probes and operatively coupled to the support structure, and a probe repositioning assembly. The probe repositioning assembly is configured to facilitate selective adjustment of an orientation of the respective probe of at least one probe assembly of the one or more probe assemblies relative to the support structure. The customizable probe card is configured to be selectively reconfigured for operative use with each of a plurality of distinct DUTs by selectively repositioning the respective probe of at least one probe assembly of the one or more probe assemblies relative to the support structure. 
     In some examples, a probe system comprises a chuck with a chuck support surface configured to support a substrate that includes one or more DUTs, a customizable probe card configured to test the one or more DUTs, and a probe card holder configured to support the customizable probe card relative to the substrate. 
     In some examples, a method of reconfiguring a customizable probe card with at least one probe assembly comprises utilizing a probe repositioning assembly to reposition a respective probe of at least one probe assembly. In some such examples, the customizable probe card is configured to be selectively reconfigured for operative use with each of a plurality of distinct DUTs by selectively repositioning the respective probe of at least one probe assembly relative to a support structure. In some such examples, each DUT includes one or more testing locations, and the respective probe of each probe assembly of the customizable probe card is configured to interface with a respective testing location of the respective DUT to test the respective DUT. In such examples, the repositioning the respective probe of the at least one probe assembly includes bringing the respective probe of each probe assembly of the at least one probe assembly to a respective orientation that corresponds to a configuration of one of the one or more testing locations.

Similarly, all elements may not be labeled in  FIGS. 1-13 , but reference numbers associated therewith may be utilized herein for consistency. Elements, components, and/or features that are discussed herein with reference to any of  FIGS. 1-13  also may be included in and/or utilized with the subject matter of any other of  FIGS. 1-13  without departing from the scope of the present disclosure. In general, elements that are likely to be included in a particular embodiment are illustrated in solid lines, while elements that are optional are illustrated in dashed lines. However, elements that are shown in solid lines may not be essential and, in some embodiments, may be omitted without departing from the scope of the present disclosure. 
       FIGS. 1-2  schematically illustrate examples of probe systems  10  and/or of customizable probe cards  100  according to the present disclosure. Specifically,  FIG. 1  is a schematic side view of examples of probe systems  10  including examples of customizable probe cards  100 , while  FIG. 2  is a schematic top view representing aspects of the functionality of customizable probe cards  100 , as described herein. As schematically illustrated in  FIGS. 1-2 , probe systems  10  and/or customizable probe cards  100  may be adapted, configured, designed, shaped, sized, and/or constructed to test one or more devices under test (DUTs)  42 , which may be formed on, supported by, and/or included in a substrate  40 . Specifically, and as schematically illustrated in  FIGS. 1-2 , probe systems  10  are configured such that customizable probe card  100  is positioned relative to DUT(s)  42  in a manner that facilitates testing the DUT(s) with one or more probes  130  of the customizable probe card. 
     Substrate  40  may include and/or be any suitable structure that may support, include, and/or have formed thereon DUT  42 . Examples of substrate  40  include a wafer, a semiconductor wafer, a silicon wafer, a gallium nitride wafer, and/or a gallium arsenide wafer. Similarly, DUT  42  may include and/or be any suitable structure that may be probed and/or tested by probe system  10 . As examples, DUT  42  may include a semiconductor device, an electronic device, an optical device, an optoelectronic device, a logic device, a power device, a switching device, and/or a transistor. 
     Conventional probe systems may utilize a conventional probe card that includes one or more probes for testing one or more corresponding DUTs. Such conventional probe cards generally are configured such that a spatial orientation and/or configuration of the probe(s) attached thereto is fixed and corresponds to a spatial orientation and/or configuration of the corresponding DUT(s) formed on the substrate. However, such probe cards may require replacement in order for the corresponding probe system to be utilized to test substrates and/or DUTs that are differently configured. 
     To mitigate such inefficiency and/or expense, customizable probe cards  100  according to the present disclosure are configured to facilitate reconfiguration of probes  130  such that the customizable probe card may be utilized with any of a plurality of differently configured substrates and/or DUTs. For example, and as discussed in more detail herein,  FIG. 2  schematically illustrates an example of customizable probe card  100  in which each probe  130  is configured to be selectively relocated between at least a first position (schematically illustrated in solid lines) and a second position (schematically illustrated in dashed lines), with the probes being aligned with distinct sets of DUTs  42  in the first position and in the second position. In this manner, customizable probe card  100  may be selectively customized, adjusted, and/or reconfigured to modify a configuration, an orientation, a layout, etc. of the probes in order to test corresponding DUTs  42  with distinct spatial distributions and/or configurations. As used herein, customizable probe card  100  also may be referred to as an adjustable probe card  100 , a reconfigurable probe card  100 , and/or a customized probe card  100 . 
     As schematically illustrated in  FIGS. 1-2 , a customizable probe card  100  includes a support structure  110 , one or more probe assemblies  120  operatively coupled to and/or supported by the support structure, and a probe repositioning assembly  104 . More specifically, and as schematically illustrated in  FIGS. 1-2 , each probe assembly  120  includes a respective probe  130 . In some examples, and as schematically illustrated in  FIGS. 1-2 , each probe assembly  120  includes a respective probe holder  140  that engages, holds, and/or supports the respective probe. Each probe holder  140  may support the respective probe  130  in any of a variety of manners such that the respective probe may be operatively positioned to test the corresponding DUT  42 . 
     In some examples, and as schematically illustrated in  FIGS. 1-2 , support structure  110  defines an aperture  111 , and at least a portion of at least one probe assembly  120  extends through the aperture to interface with a corresponding DUT  42 . As a more specific example, and as schematically illustrated in  FIGS. 1-2 , at least one probe assembly  120  may be configured such that the respective probe holder  140  and/or the respective probe  130  extends through aperture  111  during operative use of customizable probe card  100 . In this manner, and as schematically illustrated in  FIGS. 1-2 , each probe assembly  120  may be operatively coupled to and/or supported by an upper side of support structure  110 , with each probe  130  being positioned to test a corresponding DUT  42  of substrate  40  that is positioned below the support structure. Support structure  110  may include and/or be any suitable structure for supporting each probe assembly  120  relative to substrate  40 , examples of which include a surface that is at least substantially flat, a surface that is at least substantially planar, a plate, a rigid plate, an electrically conductive plate, an electrically insulating plate, an at least partially dielectric plate, and/or an at least partially metallic plate. Additionally or alternatively, in some examples, and as schematically illustrated in  FIG. 1 , customizable probe card  100  defines a normal axis  116  such that support structure  110  extends at least substantially perpendicular to the normal axis. Stated differently, support structure  110  may be described as extending within a plane that is at least substantially perpendicular to normal axis  116 . 
     As used herein, the terms “operative use,” “operatively utilized,” and the like, as used to describe a configuration in which probe system  10  and/or customizable probe card  100  operates to test substrate  40  and/or DUT(s)  42 , generally relate to examples in which the probe system supports the substrate and the customizable probe card is operable to test at least one DUT on the substrate. For example, probe system  10  and/or customizable probe card  100  may be described as being in operative use when at least one probe  130  of the customizable probe card is positioned to engage and/or interface with a respective testing location  44  for testing a corresponding DUT  42 , is configured to provide test signal  72  to the testing location, and/or is configured to receive resultant signal  74  from the testing location. However, such descriptions are not limiting with respect to the structures and components described herein, and it is to be understood that the structures and components disclosed herein do not require that customizable probe card  100  always be in operative use and/or operatively positioned relative to substrate  40  and/or DUT(s)  42 . 
     Each probe  130  may have any appropriate form and/or structure for testing DUT  42 . In particular, and as schematically illustrated in  FIGS. 1-2 , each DUT  42  may include one or more testing locations  44  such that the respective probe  130  of each probe assembly  120  of customizable probe card  100  is configured to interface with a respective testing location  44  to test DUT  42 . In some examples, such as in the example of  FIG. 2 , each DUT  42  includes a single respective testing location  44 , such that each probe assembly  120  of customizable probe card  100  is configured to test a corresponding DUT  42 . In other examples, and as schematically illustrated in  FIG. 1 , at least one DUT  42  of substrate  40  includes a plurality of respective testing locations  44 . In all such examples, utilizing customizable probe card  100  to test each DUT  42  may require that each probe  130  be aligned with the respective testing location  44 . Accordingly, and as discussed in more detail herein, customizable probe cards  100  according to the present disclosure are configured to facilitate selective repositioning and/or reconfiguration of probes  130  relative to support structure  110  and/or relative to one another, thereby enabling customizable probe card  100  to test DUTs  42  with distinct configurations. As used herein, the term “aligned,” as used to describe a relative orientation of a probe  130  (and/or a portion thereof) and a corresponding DUT  42  (and/or a portion thereof), generally refers to a configuration in which the probe is at least substantially vertically aligned with the corresponding DUT, at least substantially horizontally aligned with the corresponding DUT, at least substantially aligned with a corresponding testing location  44  of the corresponding DUT, and/or positioned such that a corresponding probe  130  contacts the corresponding testing location. 
     As used herein, directional terms such as “horizontal,” “vertical,” and the like generally refer to a configuration in which substrate  40  extends at least substantially parallel to the ground and in which customizable probe card  100  is positioned vertically above the substrate. Similarly, as used herein, positional terms such as “above,” “over,” “below,” “underneath,” and the like generally refer to relative positions along a vertical direction, such as along the Z-direction that is illustrated in  FIG. 1 . For example,  FIG. 1  may be described as schematically illustrating a configuration in which each probe  130  is positioned above substrate  40 . However, such configurations are not required, and it is additionally within the scope of the present disclosure that customizable probe card  100  may have any suitable orientation relative to substrate  40  and/or relative to the ground. 
     Customizable probe card  100  may be configured to interface with testing locations  44  in any of a variety of forms. As examples, each testing location  44  may include and/or be a contact pad, a solder bump, an optical coupler, etc. In some examples, each probe  130  has a form corresponding to a form of each testing location  44 . As an example, probe  130  may be a vertical probe, such as may be configured to contact a respective testing location  44  in the form of a solder bump of a corresponding DUT  42 . As another example, and as schematically illustrated in  FIG. 1 , probe  130  may be a cantilever probe that is configured to contact a respective testing location  44  in the form of a contact pad  44  of a corresponding DUT  42 . In other examples, the respective probe  130  and/or the respective probe tip  134  of at least one probe assembly  120  may be configured for non-contact testing of DUT  42 . For example, at least one probe  130  may be an optical probe and/or a probe antenna, such as a probe that is configured to be optically and/or electromagnetically coupled to testing location  44  for non-contact testing of DUT  42 . 
     In some examples, and as schematically illustrated in  FIGS. 1-2 , the respective probe  130  of at least one probe assembly  120  includes a respective probe body  132  that is operatively coupled to the respective probe holder  140  and a respective probe tip  134  configured to test DUT  42 . Stated differently, in such examples, probe tip  134  is configured to interface with testing location  44  to test DUT  42 . In some such examples, probe body  132  is configured to be selectively and repeatedly operatively coupled to and uncoupled from the respective probe holder  140 , such as to permit replacement of probe  130  if the probe becomes damaged and/or otherwise unsuitable for testing DUT  42 . In some such examples, probe body  132  and/or probe tip  134  includes and/or is a microelectromechanical system (MEMS) device. In some examples, probe body  132  additionally or alternatively may be referred to as a probe blade  132 . 
     As schematically illustrated in  FIG. 1 , each probe  130  and/or the respective probe tip  134  may be configured to provide a corresponding test signal  72  to DUT  42  and/or to receive a corresponding resultant signal  74  from DUT  42 . Test signal  72  may include and/or be a direct current test signal, an alternating current test signal, an analog test signal, and/or a digital test signal. In some examples, and as schematically illustrated in  FIG. 1 , probe system  10  additionally includes a signal generation and analysis assembly  70  that may be configured to provide each test signal  72  to probe assembly  120  and/or to receive each resultant signal  74  from probe assembly  120 . 
     As described in more detail herein, probe repositioning assembly  104  is configured to facilitate selective adjustment of a relative position and/or orientation of the respective probe  130  of at least one probe assembly  120  relative to support structure  110 . In this manner, customizable probe card  100  may be selectively reconfigured for operative use with distinct substrates  40  and/or distinct DUTs  42  by selectively repositioning the respective probe  130  of at least one probe assembly  120  relative to support structure  110 . Stated differently, customizable probe card  100  may be configured to be utilized to test DUTs  42  (e.g., individual DUTs  42  and/or substrates  40  including corresponding pluralities of DUTs  42 ) with corresponding testing locations  44  that differ in position and/or orientation (e.g., with respect to support structure  110 ) by selectively repositioning one or more probes  130  to conform to the configuration of testing locations  44 . In this manner, customizable probe card  100  may be selectively configured and utilized to test DUTs with any of a plurality of distinct forms and/or distributions of testing locations  44  without necessitating a corresponding plurality of distinct conventional probe cards. 
     As described in more detail herein, probe repositioning assembly  104  may form a portion of, and/or be at least partially defined by, each probe assembly  120 . As a more specific example, and as schematically illustrated in  FIGS. 1-2 , at least one probe assembly  120  may include a respective probe repositioning mechanism  106 , such that probe repositioning assembly  104  of customizable probe card  100  includes and/or is the collection of the respective probe repositioning mechanism(s)  106  of probe assembly(ies)  120 . 
     As schematically illustrated in  FIGS. 1-2 , each probe assembly  120  and/or the respective probe holder  140  thereof may be operatively coupled to and/or supported by support structure  110  and thus may support the respective probe  130  relative to support structure  110 . In this manner, probe holder  140  may include and/or be any appropriate structure that at least partially engages, holds, and/or supports probe  130  in position relative to support structure  110 . As examples, probe holder  140  may include and/or be a clamp, a slot, a fixture, a socket, etc. for retaining probe  130 . 
     In various examples, and as described in more detail herein, probe repositioning assembly  104  and/or the respective probe repositioning mechanism  106  of at least one probe assembly  120  is configured to facilitate selectively repositioning at least one probe assembly  120  and/or the respective probe holder  140  thereof relative to support structure  110  to selectively reposition the respective probe(s)  130  relative to the support structure. In some examples, and as schematically illustrated in  FIGS. 1-2 , probe repositioning assembly  104 , at least one probe assembly  120 , and/or the respective probe repositioning mechanism  106  thereof includes a probe translation stage  150  that operatively supports the respective probe holder  140  and/or the respective probe  130  of the probe assembly relative to support structure  110  and that is configured to selectively reposition the respective probe holder relative to the support structure. Stated differently, in such examples, and as schematically illustrated in  FIG. 2 , probe translation stage  150  may be fixedly coupled to support structure  110  during adjustment of the respective probe  130  relative to support structure  110 , and the probe translation stage may be configured to move the respective probe holder  140  and/or the respective probe  130  relative to the support structure through a probe range of motion associated with the probe translation stage to configure customizable probe card  100  for a particular configuration of testing locations  44 . More specifically,  FIG. 2  schematically illustrates an example in which probe repositioning assembly  104  includes a pair of probe translation stages  150 , each of which supports a respective probe holder  140 . In the example of  FIG. 2 , each probe translation stage operates to reposition the probe holder relative to support structure  110  between the first position schematically illustrated in solid lines and the second position schematically illustrated in dashed lines (and/or to any other position between the first position and the second position). In some examples, the respective probe holder  140  of at least one probe assembly  120  may be directly coupled to and/or supported by the respective probe translation stage  150 . In some such examples, the respective probe translation stage  150  may be described as including and/or defining the respective probe holder  140 . 
     In some examples, the respective probe holder  140  and/or the respective probe translation stage  150  of at least one probe assembly  120  are configured to be selectively removed from support structure  110 . As a more specific example, the respective probe translation stage  150  of at least one probe assembly  120  may be configured to be selectively and repeatedly operatively coupled to and uncoupled from support structure  110  without damage to the respective probe translation stage. Additionally or alternatively, the respective probe holder  140  and/or the respective probe translation stage  150  of at least one probe assembly  120  may be configured such that the respective probe holder may be selectively and repeatedly operatively coupled to and uncoupled from the respective probe translation stage. 
     Each probe translation stage  150  may be configured to move the respective probe holder  140  and/or the respective probe  130  relative to support structure  110  in any of a variety of manners, such as by selectively translating and/or selectively rotating the respective probe holder and/or the respective probe relative to support structure  110 . As examples, each probe translation stage  150  may be configured to translate the respective probe holder  140  and/or the respective probe  130  relative to support structure  110  along one or more linear dimensions. More specifically, such linear dimensions may include one or more linear dimensions that extend at least substantially parallel to normal axis  116  and/or one or more linear dimensions that extend at least substantially perpendicular to the normal axis. Additionally or alternatively, each probe translation stage  150  may be configured to rotate the respective probe holder and/or the respective probe relative to the support structure  110 , such as about an axis that is at least substantially parallel to normal axis  116  and/or about an axis that is at least substantially perpendicular to the normal axis. In this manner, each probe translation stage  150  may be utilized to operatively translate the respective probe  130  throughout the probe range of motion, thereby operatively translating each probe relative to substrate  40  and/or DUT(s)  42 . In some examples, the respective probe translation stages  150  of each probe assembly  120  collectively may be utilized to operatively align the respective probes  130  with specific, target, and/or desired testing locations  44  on substrate  40  and/or on DUT  42 , such as to permit communication between the respective probes and the substrate and/or DUT. This may include operative translation of each respective probe  130  in a plurality of different, separate, distinct, perpendicular, and/or orthogonal directions, such as the X-, Y-, and/or Z-directions that are illustrated in  FIG. 1 . Additionally or alternatively, this may include operative rotation of each respective probe  130  about one or more axes, such as axes that are at least substantially parallel with one or more of the X-, Y-, and/or Z-directions that are illustrated in  FIG. 1 . In the example of  FIG. 1 , the X- and Y-directions may be parallel, or at least substantially parallel, to substrate  40 , while the Z-direction may be perpendicular, or at least substantially perpendicular, to substrate  40 . However, this specific configuration is not required. 
     Each probe translation stage  150  may include and/or be any suitable structure that may be operatively attached to the respective probe holder  140  and/or the respective probe  130 , and/or that may be configured to operatively translate and/or rotate the respective probe  130  throughout the probe range-of-motion, such as may extend in three orthogonal, or at least substantially orthogonal, axes, such as the X-, Y-, and Z-axes of  FIG. 1 . As examples, each probe translation stage  150  may include one or more translation stages, lead screws, ball screws, rack and pinion assemblies, motors, stepper motors, electrical actuators, mechanical actuators, piezoelectric actuators, micrometers, and/or manual actuators. 
     In some examples, the respective probe translation stage  150  of at least one probe assembly  120  may include and/or be a manually actuated stage, such as a stage that is configured to move the respective probe  130  via manual adjustment of one or more actuators. Additionally or alternatively, the respective probe translation stage  150  of at least one probe assembly  120  may include and/or be a motorized, automated, or electrically actuated stage. 
     In an example in which probe translation stage  150  is a motorized stage, the probe translation stage may be controlled in any of a variety of manners. For example, and as schematically illustrated in  FIG. 1 , probe system  10  may include a controller  80  that is configured to at least partially control the operation of probe system  10 . In some examples, and as schematically illustrated in  FIG. 1 , controller  80  may be configured to transmit a stage control signal  86  to the respective probe translation stage  150  of at least one probe assembly  120 , such as via a wired connection. 
     In some such examples, and as schematically illustrated in  FIG. 1 , controller  80  is a network-connected device that is configured to receive a wireless control signal  82  from a user interface device  84  such that stage control signal  86  is at least partially based upon the wireless control signal. In such examples, controller  80  and/or user interface device  84  each may include and/or be any of a plurality of suitable devices and/or interfaces, examples of which include a computer, a software program, a Web site, a mobile phone, and an Internet-connected device. For example, and as schematically illustrated in  FIG. 1 , user interface device  84  may be a device that is configured to provide a user with a user interface  88  for receiving an input corresponding to a desired adjustment of the respective probe translation stage  150  of at least one probe assembly  120 . As more specific examples, user interface  88  may enable the user to specify a target destination of at least one probe  130  (e.g., relative to support structure  110  and/or substrate  40 ), a desired translation and/or rotation of at least one probe by the respective probe translation stage  150 , a desired relative orientation between a given probe assembly  120  and support structure  110 , etc. 
     In some examples, controller  80  may be associated with, and/or a component of, signal generation and analysis assembly  70  of probe system  10 . That is, while  FIG. 1  schematically illustrates signal generation and analysis assembly  70  and controller  80  as being distinct devices, this is not required. For example, it is additionally within the scope of the present disclosure that signal generation and analysis assembly  70  and controller  80  may be a common device, and/or may refer to respective portions and/or functions of a common device. 
     Signal generation and analysis assembly  70  and/or controller  80  each may be any suitable device or devices that are configured to perform the functions of the controller discussed herein. For example, the signal generation and analysis assembly and/or the controller each may include one or more of an electronic controller, a dedicated controller, a special-purpose controller, a personal computer, a special-purpose computer, a display device, a logic device, a memory device, and/or a memory device having non-transitory computer readable media suitable for storing computer-executable instructions for implementing aspects of systems and/or methods according to the present disclosure. 
     Additionally or alternatively, signal generation and analysis assembly  70  and/or controller  80  each may include, or be configured to read, non-transitory computer readable storage, or memory, media suitable for storing computer-executable instructions, or software, for implementing methods or steps of methods according to the present disclosure. Examples of such media include CD-ROMs, disks, hard drives, flash memory, etc. As used herein, storage, or memory, devices and media having computer-executable instructions as well as computer-implemented methods and other methods according to the present disclosure are considered to be within the scope of subject matter deemed patentable in accordance with Section  101  of Title  35  of the United States Code. 
     Signal generation and analysis assembly  70  additionally or alternatively may include and/or be any suitable structure that may, or that may be configured to, generate test signal  72 , transmit test signal  72 , receive resultant signal  74 , and/or analyze resultant signal  74 . Examples of signal generation and analysis assembly  70  include a signal generator, an electric signal generator, an optical signal generator, a wireless signal generator, an electromagnetic signal generator, a signal detector, an electric signal detector, an optical signal detector, a wireless signal detector, and/or an electromagnetic signal detector. 
     While the foregoing discussion generally relates to examples in which each probe  130  is repositionable within a range of motion of the respective probe translation stages  150 , it is additionally within the scope of the present disclosure that each probe  130  may be selectively repositioned independent of a probe translation stage and/or beyond a range of motion thereof. For example, customizable probe card  100  may be configured such that the respective probe  130  of at least one probe assembly  120  may be selectively repositioned relative to support structure  110  via selective placement of the associated probe assembly  120  and/or the respective probe holder  140  thereof relative to support structure  110 , such as by selectively repositioning a location at which the probe assembly and/or the respective probe holder is operatively coupled to and/or supported by the support structure. As a more specific example, and as schematically illustrated in  FIGS. 1-2 , at least one probe assembly  120  may include a respective probe assembly mounting structure  160  that is configured to be operatively coupled to support structure  110  to selectively and operatively couple and/or retain the probe assembly to the support structure at a selected location on and/or relative to the support structure. Stated differently, in such examples, the respective probe assembly mounting structure  160  of each probe assembly  120  may be configured to selectively and operatively couple the probe assembly and/or the respective probe holder  140  to (and/or relative to) support structure  110  at any of a plurality of distinct locations on the support structure. That is, in such examples, probe assembly mounting structure  160  may be configured to be operatively coupled to support structure  110  at any of a plurality of distinct selected locations and/or orientations relative to the support structure in order to reposition the respective probe assembly  120  and/or the respective probe holder  140  relative to the support structure. In some examples, the plurality of distinct selected locations and/or orientations includes and/or is a continuous plurality and/or distribution of selected locations and/or orientations. Stated differently, in such examples, probe assembly mounting structure  160  may be configured such that the location and/or orientation of the respective probe assembly  120  relative to support structure  110  is continuously variable and/or infinitely variable. Stated yet another way, probe assembly mounting structure  160  may be configured to be coupled to support structure  110  at any location and/or with any orientation within a continuous range of locations and/or orientations. In some examples, and as described herein, the respective probe assembly mounting structure  160  also is configured to selectively and operatively uncouple the probe assembly from the support structure, such as to facilitate repositioning probe assembly  120  relative to the support structure. 
     In some examples, probe repositioning assembly  104  may be described as including and/or being the respective probe assembly mounting structure  160  of each probe assembly  120 . Similarly, in some examples, the respective probe repositioning mechanism  106  of each probe assembly  120  may include and/or be the respective probe assembly mounting structure  160  of the probe assembly. 
       FIG. 2  schematically illustrates an example in which probe repositioning assembly  104  includes a pair of probe assembly mounting structures  160 , each of which supports a respective probe holder  140 . In the example of  FIG. 2 , each probe assembly mounting structure  160  may be selectively coupled to and uncoupled from support structure  110 , such as to move each probe assembly mounting structure (and/or the corresponding probe assembly  120 ) between a first position, schematically illustrated in solid lines, and a second position, schematically illustrated in dashed lines, for testing DUTs  42  and/or testing locations  44  with distinct locations and/or configurations. In this manner, in such examples, each probe assembly  120  and/or the respective probe holder  140  generally is configured to be selectively moved relative to support structure  110  while reconfiguring customizable probe card  100 , and to be selectively fixed (or at least substantially fixed) in position relative to support structure  110  during operative use of the customizable probe card to test DUT(s)  42 . In some such examples, the respective probe assembly mounting structure  160  of at least one probe assembly  120  may operatively support and/or include the respective probe translation stage  150  of the probe assembly. 
     While  FIG. 1  schematically illustrates each probe holder  140  as being operatively coupled to support structure  110  via probe translation stage  150  or via probe assembly mounting structure  160  (i.e., via a structure that is distinct from the probe holder), this is not required. For example, it is additionally within the scope of the present disclosure that probe holder  140  may be directly coupled to support structure  110 . In such examples, probe holder  140  may be described as including and/or being probe assembly mounting structure  160 . 
     Each probe assembly mounting structure  160  may be selectively and operatively retained in position relative to support structure  110  in any appropriate manner. As examples, each probe assembly mounting structure  160  may be configured to be selectively retained in position relative to support structure  110  via a magnetic force, a mechanical force, and/or a suction force, such as a suction force produced by applying a vacuum (e.g., at least substantially evacuating of air) to an interface region between the probe assembly mounting structure and the support structure. 
     In some examples, and as schematically illustrated in  FIG. 1 , probe repositioning assembly  104  includes a magnetic plate  114  such that at least one probe assembly mounting structure  160  may be selectively magnetically coupled to the magnetic plate at a selected position on the magnetic plate. For example, the respective probe assembly mounting structure  160  of at least one probe assembly  120  may include and/or be a magnetized material such as a permanent magnet and/or an electromagnet, and magnetic plate  114  may include and/or be a magnetized material and/or a ferromagnetic material. Additionally or alternatively, magnetic plate  114  may include and/or be a magnetized material such as a permanent magnet and/or an electromagnet, and the respective probe assembly mounting structure  160  of at least one probe assembly  120  may include and/or be a magnetized material and/or a ferromagnetic material. In some examples, and as schematically illustrated in  FIG. 1 , the respective probe assembly mounting structure  160  of at least one probe assembly  120  may include a magnetic plate coupling material  164  that is configured to magnetically couple the respective probe assembly mounting structure to magnetic plate  114 . In such examples, magnetic plate coupling material  164  may include and/or be a magnetized material, a ferromagnetic material, and/or a permanent magnet. 
     In some examples, magnetic plate  114  is at least substantially fixed relative to support structure  110  and/or fixedly coupled to the support structure. While  FIG. 1  schematically illustrates magnetic plate  114  as being distinct from support structure  110 , this is not required, and it is additionally within the scope of the present disclosure that support structure  110  includes, and/or is, magnetic plate  114 . 
     In some examples, the respective probe assembly mounting structure  160  of at least one probe assembly  120  may be configured to be selectively magnetically coupled to magnetic plate  114  via a variable magnetic force. As a more specific example, magnetic plate  114  and/or the respective probe assembly mounting structure  160  of at least one probe assembly  120  may include and/or be an electromagnet that is configured to be selectively magnetized to selectively fix the respective probe assembly mounting structure in position relative to the magnetic plate during operative use of customizable probe card  100 . In such examples, the electromagnet may be selectively demagnetized to permit the respective probe assembly mounting structure to be selectively repositioned relative to the magnetic plate. In some examples, and as schematically illustrated in  FIG. 1 , controller  80  is configured to transmit an electromagnet control signal  94  to magnetic plate  114  and/or the respective probe assembly mounting structure  160  of at least one probe assembly  120  to at least partially control the magnetic force produced by the electromagnet. In other examples, probe assembly mounting structure  160  and magnetic plate  114  may be configured to be magnetically coupled to one another via a magnetic force that is not configured to be selectively variable. For example, one of probe assembly mounting structure  160  and magnetic plate  114  may include and/or be a permanent magnet, and the other one of the probe assembly mounting structure and the magnetic plate may be a permanent magnet or a ferromagnetic material. 
     In some examples, and as schematically illustrated in  FIG. 1 , probe repositioning assembly  104  may include a single magnetic plate  114  such that the respective probe assembly mounting structures  160  of one or more probe assemblies  120  are magnetically coupled to the single magnetic plate. In other examples, and as additionally schematically illustrated in dashed lines in  FIG. 1 , probe repositioning assembly  104  may include a plurality of magnetic plates  114  that are spaced apart from one another. In such examples, and as schematically illustrated in  FIG. 1 , the respective probe assembly mounting structures  160  of each of a plurality of probe assemblies  120  may be magnetically coupled to a respective magnetic plate  114  of the plurality of magnetic plates. In such examples, each magnetic plate  114  may be at least substantially fixed relative to support structure  110 , such that selectively translating each respective probe assembly mounting structure  160  relative to the respective magnetic plate  114  operates to translate the respective probe assembly mounting structure relative to the support structure. As used herein, references to probe assembly mounting structure  160  being operatively and/or magnetically coupled to magnetic plate  114  also may be understood as describing and/or referring to examples in which the probe assembly mounting structure is operatively and/or magnetically coupled to a respective magnetic plate of a plurality of magnetic plates. 
     In some examples, probe assembly mounting structure  160  may be configured to be magnetically coupled to magnetic plate  114  and to be selectively moved relative to the magnetic plate by introducing a pressurized gas between the probe assembly mounting structure and the magnetic plate. More specifically, and as schematically illustrated in  FIG. 1 , probe system  10  may include a gas source  66  that is configured to generate a pressurized flow of a gas, such as air, as well as a gas conduit  64  extending from the gas source to convey the pressurized flow from the gas source. 
     As schematically illustrated in  FIG. 1 , at least one probe assembly mounting structure  160  may include a gas connector  162  that is configured to be fluidly connected to gas conduit  64  to receive the pressurized flow of gas and to convey the pressurized flow to an interface between the probe assembly mounting structure and magnetic plate  114 . Additionally or alternatively, and as also schematically illustrated in  FIG. 1 , support structure  110  and/or magnetic plate  114  may include gas connector  162  configured to be fluidly connected to gas conduit  64  to receive the pressurized flow of gas and to convey the pressurized flow to the interface between probe assembly mounting structure  160  and magnetic plate  114 . More specifically, in such examples, an upper surface of magnetic plate  114  may be perforated to permit the pressurized flow of gas to flow out of the magnetic plate. In this manner, selectively introducing the pressurized gas between probe assembly mounting structure  160  and magnetic plate  114  operates to reduce a friction between the probe assembly mounting structure and the magnetic plate, thereby facilitating selective repositioning of the probe assembly mounting structure relative to the magnetic plate. 
     In some such examples, and as schematically illustrated in  FIG. 1 , probe system  10  additionally includes a valve  65  for selectively regulating a flow through gas conduit  64 , such as a flow of the pressurized flow of gas, such as by selectively blocking a flow through the gas conduit. For example, and as schematically illustrated in  FIG. 1 , controller  80  may be configured to transmit a valve control signal  96  to valve  65  to regulate the pressurized flow through the valve. In this manner, controller  80  may enable remote control of valve  65  to selectively permit the pressurized flow to reach probe assembly mounting structure  160  and/or magnetic plate  114  for selective repositioning of the probe assembly mounting structure and/or to selectively restrict the pressurized flow from reaching the probe assembly mounting structure and/or the magnetic plate during operative use of customizable probe card  100  to test DUT(s)  42 . 
     In other examples, and as discussed, probe assembly mounting structure  160  may be configured to be selectively retained in position relative to support structure  110  via a suction force. In some such examples, and as schematically illustrated in  FIG. 1 , probe system  10  includes a vacuum source  68  that is configured to pull gas and/or air through a conduit such as gas conduit  64 , which in turn may be operatively fluidly coupled to probe assembly mounting structure  160  via gas connector  162  of the probe assembly mounting structure. Additionally or alternatively, and as also schematically illustrated in  FIG. 1 , gas conduit  64  may be operatively fluidly coupled to support structure  110  and/or to magnetic plate  114  via gas connector  162  associated with the support structure and/or the magnetic plate. 
     Accordingly, in such examples, vacuum source  68  may be configured to selectively apply a vacuum to the interface region between probe assembly mounting structure  160  and support structure  110  (and/or between probe assembly mounting structure  160  and magnetic plate  114 ) by drawing air through gas conduit  64 , thereby selectively retaining the probe assembly mounting structure relative to the support structure via a suction force. In such examples, valve  65  may be configured to selectively fluidly connect vacuum source  68  to probe assembly mounting structure  160 , support structure  110 , and/or magnetic plate  114  to selectively retain the probe assembly mounting structure relative to the support structure. 
     The foregoing examples generally correspond to examples in which a force (e.g., a magnetic force and/or a suction force) retaining probe assembly mounting structure  160  relative to support structure  110  and/or magnetic plate  114  may be selectively reduced, mitigated, and/or opposed to facilitate selectively repositioning the probe assembly mounting structure relative to the support structure. However, this is not required of all examples of customizable probe card  100 , and it is additionally within the scope of the present disclosure that probe assembly mounting structure  160  may be configured to be selectively repositioned relative to support structure  110  without diminishing and/or counteracting a force that retains the probe assembly mounting structure relative to the support structure. For example, in an example in which probe assembly mounting structure  160  is retained in position relative to magnetic plate  114  via a magnetic force, the probe assembly mounting structure may be configured to be selectively translated relative to the magnetic plate while the probe assembly mounting structure is operatively magnetically coupled to the magnetic plate. More specifically, in such examples, the magnitude of the attractive magnetic force that retains the probe assembly mounting structure against the magnetic plate may be sufficiently strong to retain the probe assembly mounting structure in a static position during operative use of customizable probe card  100 . In such examples, the magnitude of the attractive magnetic force also may be sufficiently weak to enable the probe assembly mounting structure to be selectively translated relative to the magnetic plate, such as along a surface of the magnetic plate, along a surface of support structure  110 , and/or along a direction at least substantially perpendicular to normal axis  116 , while the probe assembly mounting structure remains operatively magnetically coupled to the magnetic plate. 
     The foregoing examples generally correspond to examples in which probe assembly mounting structure  160  enables selectively repositioning the respective probe  130  and/or the respective probe holder  140  relative to support structure  110  along a direction at least substantially perpendicular to normal axis  116 , such as by moving the probe assembly mounting structure  160  along a surface of the support structure and/or of magnetic plate  114 . In some examples, probe assembly mounting structure  160  additionally or alternatively may be configured to enable repositioning the respective probe  130  and/or the respective probe holder  140  relative to support structure  110  along a direction at least substantially parallel to normal axis  116 , such as by selectively translating the respective probe holder relative to the probe assembly mounting structure. As a more specific example, the respective probe holder  140  of at least one probe assembly  120  may be operatively coupled to the respective probe assembly mounting structure  160  at least partially via a magnetic force in a manner that enables and/or facilitates selectively translating the respective probe holder relative to the respective probe assembly mounting structure. In some such examples, one or both of the respective probe holder  140  and the respective probe assembly mounting structure  160  includes and/or is a magnetized material, a ferromagnetic material, and/or a permanent magnet. 
     As a more specific example, and as schematically illustrated in  FIG. 1 , probe holder  140  may include mounting structure coupling material  142  that is configured to magnetically couple the probe holder to the respective probe assembly mounting structure  160 . Additionally or alternatively, and as schematically illustrated in  FIG. 1 , probe assembly mounting structure  160  may include a probe holder coupling material  166  that is configured to magnetically couple the probe assembly mounting structure to the respective probe holder  140 . In such examples, each of mounting structure coupling material  142  and/or probe holder coupling material  166  may include and/or be a magnetized material, a ferromagnetic material, and/or a permanent magnet. In such examples, probe holder  140  may be configured to be selectively translated relative to the respective probe assembly mounting structure  160  along a direction at least substantially parallel to normal axis  116  while the probe holder is operatively magnetically coupled to the respective probe assembly mounting structure  160 . 
     In an example in which probe repositioning assembly  104  includes probe assembly mounting structure(s)  160 , each probe assembly mounting structure may be selectively positioned upon support structure  110 , and/or repositioned relative to the support structure, in any appropriate manner. As an example, the respective probe assembly mounting structure  160  of at least one probe assembly  120  may be configured to be manually repositioned relative to support structure  110 . 
     Additionally or alternatively, in some examples, and as schematically illustrated in  FIG. 1 , probe system  10  and/or probe repositioning assembly  104  may include a repositioning jig  108  that is configured to facilitate repositioning each probe assembly mounting structure  160  and/or to facilitate alignment of each respective probe holder  140  at a predetermined orientation relative to support structure  110 . More specifically, in some such examples, repositioning jig  108  may be configured to selectively engage the respective probe assembly mounting structure  160  of at least one probe assembly  120  to bring each respective probe assembly mounting structure to a predetermined position and/or orientation relative to support structure  110 . As a more specific example, the repositioning jig may have a fixed and/or reconfigurable configuration that corresponds to a configuration of testing locations  44  such that engaging each probe assembly mounting structure  160  with the repositioning jig operates to move, or facilitate moving, each probe assembly mounting structure to a position such that each probe  130  is at least substantially aligned with a corresponding testing location  44 . Repositioning jig  108  may include and/or be any of a variety of suitable structures and/or mechanisms configured to position, to accurately position, to selectively position, to reposition, to accurately reposition, and/or to selectively reposition probe assembly mounting structure  160  on and/or relative to support structure  110 . Examples of repositioning jig  108  include a motorized jig, a manually adjustable jig, and/or a robot. In other examples, repositioning jig  108  may include and/or be a template for positioning each probe  130 . 
     In some examples, support structure  110 , magnetic plate  114 , and/or the respective probe assembly mounting structure  160  of at least one probe assembly  120  may be configured such that the location of each probe assembly mounting structure upon the support structure and/or the magnetic plate is continuously and/or infinitely variable. For example, the respective probe assembly mounting structure  160  of at least one probe assembly  120  may be configured to be magnetically coupled to magnetic plate  114  at any of a continuous plurality and/or distribution of locations and/or rotational configurations relative to the magnetic plate. In this manner, the position and/or configuration of the probe assembly mounting structure relative to the magnetic plate and/or the support structure may be described as being infinitely adjustable. 
     In some examples, customizable probe card  100  is configured to be selectively and repeatedly operatively coupled to and uncoupled from one or more other components of probe system  10 . For example, and as schematically illustrated in  FIG. 1 , probe system  10  may include a probe card holder  60  that is configured to support customizable probe card  100  relative to substrate  40 . Specifically, in such examples, probe card holder  60  is configured such that customizable probe card  100  may be selectively and repeatedly operatively coupled to and uncoupled from the probe card holder. In such examples, and as schematically illustrated in  FIG. 1 , support structure  110  may include a mounting structure  112  for selectively and repeatedly operatively coupling customizable probe card  100  to probe card holder  60 . Probe card holder  60  and/or mounting structure  112  each may include and/or be any of a variety of suitable structures, such as may be known to the art of probe cards, examples of which include a mechanical fastener, a fastener receiver, a press-fit fastener, a socket, and/or a zero insertion force (ZIF) connector. As a more specific example, and as schematically illustrated in  FIG. 1 , mounting structure  112  may include one or more fasteners  62  that extend at least partially through each of probe card holder  60  and customizable probe card  100 . 
     In some examples, and as schematically illustrated in  FIG. 1 , probe system  10  includes a platen  50  that supports probe card holder  60  and/or customizable probe card  100  relative to substrate  40 . In some such examples, platen  50  includes and/or defines probe card holder  60 . Platen  50  and/or probe card holder  60  may support customizable probe card  100  in any of a variety of suitable configurations. As an example, and as schematically illustrated in  FIG. 1 , platen  50  and/or probe card holder  60  may support customizable probe card  100  such that at least a portion of the customizable probe card is positioned at least substantially below platen  50 , and/or such that at least a portion of the customizable probe card is positioned between the platen and chuck  30 . More specifically, and as schematically illustrated in  FIG. 1 , platen  50  and/or probe card holder  60  may support customizable probe card  100  such that support structure  110  is positioned at least substantially below platen  50  and/or such that the support structure is positioned between the platen and chuck  30 . In such a configuration, customizable probe card  100  and/or support structure  110  may be described as being suspended by platen  50 . Similarly, in some examples, and as schematically illustrated in  FIG. 1 , each probe repositioning mechanism  106  of probe repositioning assembly  104  (e.g., each probe translation stage  150  and/or each probe assembly mounting structure  160 ) is supported by and/or operatively coupled to a portion of support structure  110  that extends below platen  50 . 
     In some examples, and as schematically illustrated in  FIG. 1 , probe system  10  additionally includes an enclosure  12  that at least partially bounds, or defines, an enclosure volume  14 . Enclosure volume  14  may be adapted, configured, designed, shaped, sized, and/or constructed to receive and/or to contain chuck  30 , substrate  40 , platen  50 , customizable probe card  100 , support structure  110 , and/or any suitable portion thereof. In a specific example, platen  50  may at least partially bound and/or define enclosure volume  14  and support structure  110  of customizable probe card  100  may be positioned within the enclosure volume. Enclosure  12  may be an electrically conductive enclosure, and/or may be configured to at least partially shield enclosure volume  14  from the ambient environment that surrounds enclosure  12 , that is external to enclosure  12 , and/or that is external to enclosure volume  14 . As examples, enclosure  12  may shield enclosure volume  14  from electromagnetic radiation that may be present within the ambient environment, from electric fields that may be present within the ambient environment, from magnetic fields that may be present within the ambient environment, and/or from visible light that may be present within the ambient environment. In this manner, enclosure  12  may be configured to provide shielding for each DUT  42  and/or each probe  130  from electromagnetic radiation. In some examples, and as schematically illustrated in  FIG. 1 , platen  50  at least partially defines enclosure volume  14 . In some such examples, enclosure  12  may be described as including platen  50 , and/or platen  50  may be described as forming an upper surface of enclosure  12 . 
     In some examples, customizable probe card  100  includes an electrical interface  170  that is configured to transfer electrical signals between probe assembly  120  and a component of probe system  10  exterior to the customizable probe card. As more specific examples, electrical interface  170  may be configured to transfer test signal  72 , resultant signal  74 , stage control signal  86 , and/or electromagnet control signal  94  between probe assembly  120  and signal generation and analysis assembly  70 , and/or between the probe assembly and controller  80 . 
     Electrical interface  170  may include and/or be any of a variety of suitable structures, examples of which include an electrical cable connector and/or an electrical contact. In some examples, mounting structure  112  includes electrical interface  170 . In some such examples, probe card holder  60  and/or mounting structure  112  may include and/or be a socket that provides each of a mechanical coupling and an electrical coupling between customizable probe card  100  and a component of probe system  10  exterior to the customizable probe card. As a more specific example, probe card holder  60  may include and/or be a socket that is configured to selectively receive at least a portion of customizable probe card  100  such that the probe card holder supports the customizable probe card relative to substrate  40  and such that the probe card holder forms an electrical connection with the customizable probe card. Additionally or alternatively, and as schematically illustrated in  FIG. 1 , one or more probe assemblies  120  may include respective electrical interfaces  170 . As a more specific example, at least one probe assembly  120  and/or the respective probe holder  140  thereof may include a respective electrical interface  170 . 
     As schematically illustrated in  FIG. 1 , customizable probe card  100  may be characterized by a maximum linear dimension  102  of the customizable probe card. Maximum linear dimension  102  may correspond to any appropriate dimension of customizable probe card  100 , such as a length, a width, and/or a diameter of the customizable probe card. Additionally or alternatively, maximum linear dimension  102  may correspond to a diameter of the smallest sphere that can fully encompass (e.g., circumscribe) customizable probe card  100 . 
     Customizable probe card  100  may be configured such that maximum linear dimension  102  is sufficiently small to facilitate handling of the customizable probe card by a human user, such as while selectively coupling the customizable probe card to probe card holder  60  and/or while selectively removing the customizable probe card from the probe card holder. As more specific examples, maximum linear dimension  102  may be at least 5 centimeters (cm), at least 10 cm, at least 20 cm, at least 30 cm, at least 40 cm, at most 50 cm, at most 35 cm, at most 25 cm, at most 15 cm, and/or at most 7 cm. 
     In some examples, and as further schematically illustrated in  FIG. 1 , probe system  10  and/or customizable probe card  100  includes at least one imaging device  90  that is configured to receive and/or generate an optical image of at least a portion of probe system  10 . Stated differently, each imaging device  90  may be configured to receive and/or collect light that is generated and/or reflected by at least a portion of probe system  10  to form an optical image, and/or each imaging device may be configured to generate and/or transmit an image of a portion of probe system  10  within a field of view of the imaging device. As more specific examples, each imaging device  90  may be configured to generate an optical image of substrate  40 , of DUT  42 , and/or of a portion of at least one probe assembly  120  that interfaces with a respective testing location  44 . In this manner, each imaging device  90  may be configured to facilitate establishing alignment and/or contact between at least one probe  130  with a corresponding DUT  42  and/or a corresponding testing location  44  thereof. Additionally or alternatively, at least one imaging device  90  may be configured to collect electromagnetic radiation, or light, emitted by substrate  40  and/or DUT  42 . In this manner, in such examples, each such imaging device  90  may be configured to image substrate  40  and/or DUT  42  without necessitating an external light source to illuminate the substrate and/or the DUT. 
     In some examples, and as schematically illustrated in  FIG. 1 , one or more imaging devices  90  may be operatively coupled to and/or incorporated into customizable probe card  100 . As a more specific example, probe assembly  120  and/or a portion thereof (such as the respective probe holder  140 , the respective probe  130 , and/or probe body  132  of the respective probe) may support and/or include a respective imaging device  90 . In such examples, each such imaging device  90  may move at least substantially in unison with the respective probe holder  140  and/or with the respective probe  130  as the probe holder and/or the probe is selectively repositioned relative to support structure  110 . Such a configuration thus may facilitate and/or obviate an adjustment of imaging device  90  to optimize receiving the optical image of probe  130  and/or of substrate  40  subsequent to selectively reconfiguring customizable probe card  100 . Stated differently, in an example in which imaging device  90  is operatively coupled to probe  130  and/or probe holder  140 , the imaging device may be configured such that an image of the probe that is generated by the imaging device remains at least partially unchanged as the probe holder is moved relative to support structure  110 . As more specific examples, the respective imaging device  90  associated with at least one probe assembly  120  may be operatively coupled to, and/or fixed relative to, the respective probe holder  140  and/or to the respective probe  130  (such as to probe body  132  of the respective probe) such that the respective probe remains in focus to the imaging device and/or within a field of view of the imaging device while the probe holder is moved relative to support structure  110  and/or substrate  40 . 
     Each imaging device  90  may be configured to collect light along any of a variety of directions, such as a direction that is at least substantially parallel to the X-direction, the Y-direction, the Z-direction, and/or normal axis  116  as illustrated in  FIG. 1 . Each imaging device  90  may include and/or be any suitable structure that may be adapted, configured, designed, and/or constructed to generate one or more optical images of one or more probe assemblies  120  and/or of substrate  40 .

In some examples, at least one imaging device  90  may be operatively supported by a respective probe assembly  120 , such as by probe body  132  of the respective probe  130  of the respective probe assembly. 
     Probe system  10  may be configured to support substrate  40  in any appropriate manner during operative use of customizable probe card  100 . In some examples, and as schematically illustrated in  FIG. 1 , probe system  10  includes a chuck  30  with a chuck support surface  32  that operatively supports substrate  40  during operative use of customizable probe card  100  to test DUT(s)  42 .

     In some examples, chuck translation stage  20  is configured to facilitate repositioning at least a portion of customizable probe card  100  relative to substrate  40 . As examples, chuck translation stage  20  may be configured to operatively translate chuck  30  relative to customizable probe card  100  and/or to operatively rotate chuck  30  relative to the customizable probe card, such as to facilitate establishing alignment between one or more DUT(s)  42  and one or more respective probe(s)  130  to prepare probe system  10  for testing of the DUT(s). Additionally or alternatively, chuck translation stage  20  may be configured to operatively translate and/or rotate chuck  30  relative to customizable probe card  100  so as to facilitate sequential testing of a plurality of DUTs  42  by the customizable probe card, such as by moving substrate  40  relative to customizable probe card  100  such that the respective probe  130  of at least one probe assembly  120  is aligned with a different DUT and/or a different testing location  44 . 
     Chuck translation stage  20  may be configured to translate chuck  30  and/or substrate  40  relative to customizable probe card  100  along any of a plurality of directions and/or axes, such as along a first axis and along a second axis that is perpendicular, or at least substantially perpendicular, to the first axis.

As described in more detail below,  FIGS. 9-11  are less schematic illustrations of examples of customizable probe cards  100  in which the respective probe repositioning mechanism  106  of each probe assembly  120  includes a respective probe assembly mounting structure  160 . As described in more detail below,  FIGS. 12-13  illustrate examples of user interfaces  88  that may be associated with user interface device  84 . It is within the scope of the present disclosure that any of the features, aspects, components, etc. illustrated in conjunction with probe systems  10  of any of  FIGS. 3-13  additionally or alternatively may be utilized in conjunction with probe systems  10  of any other of  FIGS. 3-13 . 
       FIGS. 3-6  illustrate a customizable probe card  1000 , which is an example of customizable probe card  100 . As shown in  FIG. 3 , customizable probe card  1000  includes two probe assemblies  120 , each of which includes a portion of probe repositioning assembly  104  in the form of a respective probe repositioning mechanism  106  that includes a respective probe translation stage  150 . In this example, probe translation stage  150  of customizable probe card  1000  is a motorized translation stage. 
     As shown in  FIGS. 3-6 , and as perhaps best seen in  FIGS. 5-6 , each probe assembly  120  of customizable probe card  1000  includes a respective probe holder  140  that is supported by the respective probe translation stage  150  and that receives a respective probe  130 . In particular, in this example, each probe holder  140  is configured such that the respective probe  130  may be selectively removed from the probe holder and inserted into the probe holder, such as to facilitate exchanging the probe  130  for a new probe if the probe becomes damaged or otherwise is not well suited to test a particular DUT  42 .  FIG. 7  illustrates a particular probe  130  of customizable probe card  100  positioned relative to an example of substrate  40  including a plurality of DUTs  42  with respective testing locations  44 . In particular, in the configuration illustrated in  FIG. 7 , probe tip  134  of probe  130  is positioned to contact the respective testing location  44  of a particular DUT  42  on substrate  40 . 
       FIG. 8  illustrates a customizable probe card  1100 , which is another example of customizable probe card  100 . Customizable probe card  1100  is substantially similar to customizable probe card  1000  of  FIGS. 3-7  with the exception that the respective probe translation stage  150  of each probe assembly  120  is a manually adjustable translation stage. 
       FIG. 9  illustrates a customizable probe card  1200 , which is another example of customizable probe card  100 . As illustrated in  FIG. 9 , support structure  110  of customizable probe card  1200  includes magnetic plate  114 , and the respective probe repositioning mechanism  106  of each probe assembly  120  of customizable probe card  1200  includes a respective probe assembly mounting structure  160  that is selectively magnetically coupled to magnetic plate  114 . 
       FIG. 10  illustrates a customizable probe card  1300 , which is another example of customizable probe card  100 . Customizable probe card  1300  is substantially similar to customizable probe card  1200 . Specifically, support structure  110  of customizable probe card  1300  also includes magnetic plate  114 , and the respective probe repositioning mechanism  106  of each probe assembly  120  of customizable probe card  1300  includes a respective probe assembly mounting structure  160  that is selectively magnetically coupled to magnetic plate  114 . However, and as illustrated in  FIG. 10 , each probe assembly mounting structure  160  of customizable probe card  1300  additionally includes gas connector  162  that is configured to be operatively fluidly coupled to gas conduit  64  of probe system  10 . Specifically, in this example, introducing a pressurized flow gas to each probe assembly mounting structure  160  via gas source  66  (schematically illustrated in  FIG. 1 ) and gas connector  162  operates to introduce an air cushion between the probe assembly mounting structure and magnetic plate  114 , thereby facilitating repositioning the probe assembly mounting structure relative to magnetic plate  114 . 
       FIG. 11  illustrates a customizable probe card  1400 , which is another example of customizable probe card  100 . Similar to customizable probe card  1200  of  FIG. 9  and customizable probe card  1300  of  FIG. 10 , customizable probe card  1400  includes a plurality of probe assembly mounting structures  160  that each are configured to be magnetically retained in position relative to support structure  110 . In the example of  FIG. 11 , probe repositioning assembly  104  includes a plurality of spaced-apart magnetic plates  114  such that each probe assembly mounting structure  160  is magnetically coupled to a respective magnetic plate. In the example of  FIG. 11 , each magnetic plate  114  is concealed from view by the respective probe assembly mounting structure  160 . 
       FIG. 11  additionally illustrates an example in which each probe assembly mounting structure  160  is configured to be manually translated relative to the respective magnetic plate  114  while remaining magnetically coupled to the magnetic plate and without diminishing a strength of the magnetic coupling. In order to facilitate manual alignment of each probe  130  of customizable probe card  1400  with desired locations on substrate  40 , customizable probe card  1400  may be utilized in conjunction with imaging device  90  (e.g., as schematically illustrated in  FIG. 1 ). More specifically, in such examples, a user may view a visual representation, such as a real-time video, representing a location of probe  130  relative to substrate  40  and/or relative to a target location on the substrate while manually urging each probe assembly mounting structure  160  to move relative to support structure  110 . In such examples, the target location may be DUT  42  and/or testing location  44 , as schematically illustrated in  FIG. 1 , and/or may be a virtual target location that is visually superimposed on the optical image generated by imaging device  90 . 
       FIGS. 12-13  represent schematic illustrations of examples of user interfaces  88  that may be utilized to at least partially control operation of customizable probe card  100 , probe repositioning assembly  104 , and/or probe translation stage(s)  150 . For example, and as discussed above with reference to  FIG. 1 , probe system  10  may include controller  80  that is configured to receive a wireless control signal  82  from a user interface device  84  and to transmit a stage control signal  86  to the respective probe translation stage  150  of at least one probe assembly  120 . Accordingly,  FIGS. 12-13  schematically illustrate examples of user interfaces  88  that may be generated and/or presented by user interface device  84  to a human user and to receive an input from the user, thus enabling the user to at least partially control the operation of at least one probe translation stage  150 . 
     More specifically,  FIG. 12  schematically illustrates an example of user interface  88  in the form of an Internet-based interface that provides the user with controls for manipulating at least one probe  130  via the respective probe translation stage. In the example of  FIG. 12 , user interface  88  additionally provides the user with an image, such as a real-time image, of at least a portion of customizable probe card  100  and/or of substrate  40 , such as may be collected by imaging device  90 . In this manner, user interface  88  of  FIG. 12  may enable the user to position probe  130  relative to a corresponding DUT  42  with reference to a real-time image of the probe relative to the DUT. In the example of  FIG. 13 , user interface  88  takes the form of a screen presented by a mobile device application. In this example, user interface  88  provides the user with manual and/or semi-automated control of at least one probe translation stage  150 , and additionally provides the user with information regarding a position of the respective probe(s)  130  relative to substrate  40 , DUT  42 , and/or testing location  44 . 
       FIG. 14  is a flowchart depicting methods  200 , according to the present disclosure, of reconfiguring a customizable probe card of a probe system, such as to selectively adapt the customizable probe card for testing of a given substrate and/or DUT(s) thereof. Examples of probe systems and/or customizable probe cards that may be utilized in conjunction with methods  200  are described herein with reference to probe system  10  and/or customizable probe card  100  thereof, respectively. Examples of substrates and/or DUTs that may be utilized in conjunction with methods  200  are described herein with reference to substrate  40  and/or DUT(s)  42 , respectively. 
     As shown in  FIG. 14 , and as discussed in more detail below, a method  200  includes repositioning, at  230  and utilizing a probe repositioning assembly, a respective probe of at least one probe assembly of the customizable probe card. Examples of probe repositioning assemblies, probe assemblies, and/or probes that may be utilized in conjunction with methods  200  are described herein with reference to probe repositioning assembly  104 , probe assembly  120 , and/or probe  130 , respectively. 
     The repositioning the probe(s) at  230  may include repositioning in any of a variety of circumstances and/or manners. For example, the repositioning the probe(s) at  230  may include bringing one or more probes of the customizable probe card to a selected and/or desired position, such as relative to the substrate, relative to one or more DUTs, and/or relative to one or more testing locations. In this manner, and as discussed herein, the repositioning the probe(s) at  230  may operate to configure the customizable probe card such that the absolute and/or relative positions and/or orientations of the probes and/or of respective probe tips of the probes correspond to a relative orientation of testing locations of the substrate and/or DUT(s) that will be tested. 
     Stated differently, the repositioning the probe(s) at  230  may include bringing the probe(s) to respective positions and/or orientations that correspond to a pattern, a layout, a configuration, etc. of testing locations to be tested by the probe(s). Additionally or alternatively, the repositioning the probe(s) at  230  may include repositioning the probe(s) to correct a misalignment of the probe(s), such as relative to one another, relative to the substrate, and/or relative to another component of the customizable probe card. Stated differently, in such examples, the repositioning the probe(s) may include repositioning to correct the position(s) and/or orientation(s) of the probe(s), such as of one or more probes that are only approximately correctly positioned. As another example, the repositioning at  230  may include replacing a probe and/or a probe assembly of the customizable probe card, such as to repair and/or replace a probe tip that is damaged and/or contaminated. Examples of testing locations that may be utilized in conjunction with methods  200  are described herein with reference to testing locations  44 . 
     The repositioning the probe(s) at  230  may be performed in any of a variety of manners, such as in any suitable manner described herein. As an example, and as shown in  FIG. 2 , the repositioning at  230  may include repositioning, at  232 , each probe with a respective probe translation stage of the probe repositioning assembly. As more specific examples, the repositioning with the probe translation stage(s) at  232  may include translating the respective probe and/or the respective probe holder of each probe assembly relative to a support structure of the customizable probe card along one or more linear dimensions and/or rotating the respective probe holder(s) relative to the support structure. Examples of support structures, probe holders, and/or probe translation stages that may be utilized in conjunction with methods  200  are described herein with reference to support structure  110 , probe holder  140 , and/or probe translation stage  150 , respectively. 
     In some examples, the repositioning the probe(s) at  232  includes controlling the respective probe translation stage of at least one probe assembly at least partially remotely, such as via a stage control signal that is generated and/or transmitted via a controller. Examples of controllers and/or stage control signals are described herein with reference to controller  80  and/or stage control signal  86 , respectively. Additionally, the repositioning the probe(s) at  232  may include utilizing the probe repositioning assembly and/or the probe translation stage in conjunction with any other structures and/or mechanisms discussed herein in association with probe translation stage  150 . 
     Additionally or alternatively, and as shown in  FIG. 14 , the probe repositioning assembly and/or at least one probe assembly may include a respective probe assembly mounting structure, and the repositioning the probe(s) at  230  may include repositioning, at  240 , the respective probe assembly mounting structure of at least one such probe assembly relative to the support structure. As a more specific example, the repositioning the probe assembly mounting structure(s) at  240  may include translating the respective probe assembly mounting structure(s) along a direction at least substantially perpendicular to a normal axis associated with the customizable probe card, such as normal axis  116  described herein. In some examples, and as shown in  FIG. 14 , the repositioning the probe assembly mounting structure(s) at  240  includes moving, at  244 , each probe assembly mounting structure to a different location and/or rotational orientation upon the support structure. 
     As discussed, when present, a probe assembly mounting structure (such as probe assembly mounting structure  160  described herein) generally is configured to be selectively moved (e.g., translated and/or rotated) relative to the support structure and to be fixed in position relative to the support structure to operatively position the respective probe for testing of the DUT(s). In some examples, and as discussed herein, the probe assembly mounting structure is configured such that a force (e.g., a magnetic force and/or a suction force) that retains the probe assembly mounting structure relative to the support structure may be selectively reduced, mitigated, and/or opposed to facilitate the moving the probe assembly mounting structure(s) at  244 . Accordingly, in such examples, and as shown in  FIG. 14 , the repositioning the probe assembly mounting structure(s) at  240  may include, prior to the moving the probe assembly mounting structure(s) at  244 , uncoupling, at  242 , each probe assembly mounting structure from the support structure. Additionally or alternatively, in such examples, and as shown in  FIG. 14 , the repositioning the probe assembly mounting structure(s) at  240  may include, subsequent to the moving the probe assembly mounting structure(s) at  244 , coupling, at  246 , each probe assembly mounting structure to the support structure. 
     In an example in which the probe repositioning assembly of the customizable probe card includes one or more probe assembly mounting structures, the repositioning the probe assembly mounting structure(s) at  240  may include utilizing the probe repositioning assembly and/or each probe assembly mounting structure in conjunction with any structures and/or mechanisms discussed herein in association with probe assembly mounting structure  160 . For example, the repositioning the probe assembly mounting structure(s) at  240  may include selectively utilizing one or more structures and/or mechanisms configured for selectively retaining each probe assembly mounting structure relative to the support structure and/or for facilitating repositioning of each probe assembly mounting structure relative to the support structure. As an example, and as discussed, the probe assembly mounting structure may be configured to be operatively coupled to a magnetic plate, such as magnetic plate  114  described herein, via a magnetic force. In such an example, the uncoupling the probe assembly mounting structure(s) at  242  may include conveying a pressurized flow of gas, such as air, to the interface between the probe assembly mounting structure and the magnetic plate to at least partially urge the probe assembly mounting structure away from the magnetic plate and/or to reduce the friction between the probe assembly mounting structure and the magnetic plate. 
     As discussed herein, in such examples, the uncoupling the probe assembly mounting structure(s) at  242  may include generating the pressurized flow with a gas source, conveying the pressurized flow through a gas conduit to the probe assembly mounting structure and/or to the magnetic plate, and/or regulating the pressurized flow with a valve. Similarly, in such an example, the coupling the probe assembly mounting structure(s) at  246  may include restricting the pressurized flow, such as with the valve, such that the magnetic force between the probe assembly mounting structure and the magnetic plate maintains the probe assembly mounting structure in position relative to the support structure. In such examples, the regulating the pressurized flow with the valve and/or the restricting the pressurized flow with the valve may include controlling the valve remotely, such as by sending a valve control signal from the controller to the valve. Examples of such gas conduits, valves, valve control signals, and/or gas sources are described herein with reference to gas conduit  64 , valve  65 , valve control signal  96 , and/or gas source  66 , respectively. 
     As another example, one or both of the probe assembly mounting structure and the magnetic plate may include an electromagnet that may be selectively magnetized and demagnetized to selectively increase and decrease the magnitude of the magnetic force between the probe assembly mounting structure and the magnetic plate. In such an example, the uncoupling the probe assembly mounting structure(s) at  242  may include selectively demagnetizing the electromagnet(s) to remove the magnetic force, and/or the coupling the probe assembly mounting structure(s) at  246  may include selectively magnetizing the electromagnet(s) to apply the magnetic force. As more specific examples, the uncoupling the probe assembly mounting structure(s) at  242  and/or the coupling the probe assembly mounting structure(s) at  246  may include transmitting an electromagnet control signal, such as electromagnet control signal  94  described herein, from the controller to the electromagnet. 
     As another example, and as discussed, the probe assembly mounting structure may be configured to be operatively coupled to (e.g., retained against) the support structure and/or the magnetic plate via a suction force, such as a suction force produced by applying a vacuum to the interface between the probe assembly mounting structure and the support structure. Accordingly, in such examples, the coupling the probe assembly mounting structure(s) at  246  may include applying a vacuum to the interface region between the probe assembly mounting structure and the support structure (and/or between the probe assembly mounting structure and the magnetic plate) by drawing air through a gas conduit, thereby selectively retaining the probe assembly mounting structure relative to the support structure via a suction force. Similarly, in such examples, the uncoupling the probe assembly mounting structure(s) at  242  may include interrupting and/or ceasing the drawing of the air through the gas conduit, such as by restricting the flow of gas through the gas conduit with the valve, thereby reducing and/or removing the suction force retaining the probe assembly mounting structure against the support structure. 
     The foregoing examples generally correspond to examples in which a force (e.g., a magnetic force and/or a suction force) retaining each probe assembly mounting structure relative to the support structure and/or the magnetic plate may be selectively reduced, mitigated, and/or opposed to facilitate the moving the probe assembly mounting structure(s) at  244 . However, and as discussed, this is not required of all examples of methods  200 , and it is additionally within the scope of the present disclosure that the moving the probe assembly mounting structure(s) at  244  may include moving each probe assembly mounting structure while the probe assembly mounting structure remains operatively magnetically coupled to the magnetic plate. 
     In some examples, and as discussed, the probe repositioning assembly may include a repositioning jig, and the moving the probe assembly mounting structure(s) at  244  may include operatively engaging each probe assembly mounting structure with the repositioning jig to bring each probe assembly mounting structure to a predetermined location and/or rotational orientation relative to the support structure. Examples of such repositioning jigs are discussed herein with reference to repositioning jig  108 . As discussed, in some examples, the customizable probe card is configured to be selectively and repeatedly operatively coupled to and uncoupled from a probe card holder, such as probe card holder  60  described herein. In such examples, the repositioning the probe(s) at  230  may be performed while the customizable probe card remains operatively coupled to the probe card holder and/or operatively installed within the probe system. Stated differently, customizable probe cards  100  and/or methods  200  according to the present disclosure may enable selective reconfiguration of the customizable probe card without removing the customizable probe card from the probe card holder. 
     However, in such examples, it may be desirable to ensure that each probe is spaced apart from the substrate prior to repositioning the probes. Accordingly, in some such examples and as shown in  FIG. 14 , methods  200  further include, prior to the repositioning the probe(s) at  230 , separating, at  210 , each probe from the corresponding testing location. As examples, the separating the probe(s) at  210  may include removing each probe from contact with the corresponding testing location and/or increasing a distance between each probe and the substrate. In such examples, methods  200  additionally may include, subsequent to the repositioning the probe(s) at  230 , establishing, at  260 , an operative interface between each probe and the corresponding testing location. As examples, the establishing the interface at  260  may include contacting each probe to the corresponding testing location, or may include positioning each probe relative to the corresponding testing location to establish a non-contact testing interface between the probe and the testing location. 
     The separating the probe(s) at  210  and/or the establishing the interface at  260  may include moving each probe relative to the substrate and/or relative to the corresponding DUTs in any appropriate manner, such as by moving one or more probes with respective probe repositioning mechanisms of the respective probe assemblies and/or of the probe repositioning assembly and/or by moving the substrate with a chuck translation stage. Examples of probe repositioning mechanisms are described herein with reference to probe repositioning mechanism  106 , such as may include and/or be probe translation stage  150  and/or probe assembly mounting structure  160 . Examples of chuck translation stages are described herein with reference to chuck translation stage  20 . 
     In some examples, and as discussed, each probe assembly mounting structure additionally or alternatively may be configured to enable repositioning the respective probe and/or the respective probe holder relative to the support structure along a direction at least substantially parallel to the normal axis, such as by selectively translating the respective probe holder relative to the probe assembly mounting structure. Accordingly, in such examples, and as shown in  FIG. 14 , the repositioning the probe(s) at  230  may include translating, at  250 , the respective probe holder of at least one probe assembly relative to the respective probe assembly mounting structure, such as along a direction at least substantially parallel to the normal axis. In such examples, the translating the respective probe holder(s) at  250  may be performed with the customizable probe card operatively coupled to the probe card holder and/or prior to the establishing the interface at  260 . As a more specific example, the respective probe holder may be operatively coupled to the probe assembly mounting structure at least partially via a magnetic force, and the translating the probe holder(s) at  250  may be performed while the respective probe holder is operatively and magnetically coupled to the respective probe assembly mounting structure. 
     In some examples, and as further shown in  FIG. 14 , methods  200  additionally or alternatively may include, prior to the repositioning the probe(s) at  230 , uncoupling, at  220 , the customizable probe card from the probe card holder. In such examples, the repositioning the probe(s) at  230  may be performed with the customizable probe card removed from the probe system. 
     As further shown in  FIG. 14 , methods  200  may include repeating one or more of the separating the probe(s) at  210 , the uncoupling the customizable probe card at  220 , the repositioning the probe(s) at  230 , the repositioning the probe holder(s) at  232 , the repositioning the probe assembly mounting structure(s) at  240 , the uncoupling the probe assembly mounting structure(s) at  242 , the moving the probe assembly mounting structure(s) at  244 , the coupling the probe assembly mounting structure(s) at  246 , and/or the establishing the interface at  260 . In this manner, repeating one or more steps of methods  200  may enable and/or correspond with reconfiguring the customizable probe card for use with substrates and/or DUTs with distinct patterns and/or configurations of testing locations. As an example, the repositioning the probe(s) at  230  may include bringing each probe assembly of the customizable probe card to a first probe configuration for testing one or more DUTs in a first DUT configuration, and method  200  may include repeating the repositioning at  230  to bring each probe assembly of the customizable probe card to a second probe configuration for testing one or more DUTs in a second DUT configuration that is different than the first DUT configuration. 
     As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” may refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like. 
     As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity. 
     As used herein the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply “capable of” performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It is also within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa. 
     As used herein, the phrase “at least substantially,” when modifying a degree or relationship, includes not only the recited “substantial” degree or relationship, but also the full extent of the recited degree or relationship. A substantial amount of a recited degree or relationship may include at least 75% of the recited degree or relationship. For example, a first direction that is at least substantially parallel to a second direction includes a first direction that is within an angular deviation of 22.5° relative to the second direction and also includes a first direction that is identical to the second direction. 
     As used herein, the terms “selective” and “selectively,” when modifying an action, movement, configuration, or other activity of one or more components or characteristics of an apparatus, mean that the specific action, movement, configuration, or other activity is a direct or indirect result of one or more dynamic processes, as described herein. The terms “selective” and “selectively” thus may characterize an activity that is a direct or indirect result of user manipulation of an aspect of, or one or more components of, the apparatus, or may characterize a process that occurs automatically, such as via the mechanisms disclosed herein. 
     As used herein, the phrase, “for example,” the phrase, “as an example,” and/or simply the term “example,” when used with reference to one or more components, features, details, structures, and/or embodiments according to the present disclosure, are intended to convey that the described component, feature, detail, structure, and/or embodiment is an illustrative, non-exclusive example of components, features, details, structures, and/or embodiments according to the present disclosure. Thus, the described component, feature, detail, structure, and/or embodiment is not intended to be limiting, required, or exclusive/exhaustive; and other components, features, details, structures, and/or embodiments, including structurally and/or functionally similar and/or equivalent components, features, details, structures, and/or embodiments, are also within the scope of the present disclosure. 
     In the event that any patents, patent applications, or other references are incorporated by reference herein and (1) define a term in a manner that is inconsistent with and/or (2) are otherwise inconsistent with, either the non-incorporated portion of the present disclosure or any of the other incorporated references, the non-incorporated portion of the present disclosure shall control, and the term or incorporated disclosure therein shall only control with respect to the reference in which the term is defined and/or the incorporated disclosure was present originally. 
     In the present disclosure, several of the illustrative, non-exclusive examples have been discussed and/or presented in the context of flow diagrams, or flow charts, in which the methods are shown and described as a series of blocks, or steps. Unless specifically set forth in the accompanying description, it is within the scope of the present disclosure that the order of the blocks may vary from the illustrated order in the flow diagram, including with two or more of the blocks (or steps) occurring in a different order, concurrently, and/or repeatedly. It is also within the scope of the present disclosure that the blocks, or steps, may be implemented as logic, which also may be described as implementing the blocks, or steps, as logics. In some applications, the blocks, or steps, may represent expressions and/or actions to be performed by functionally equivalent circuits or other logic devices. The illustrated blocks may, but are not required to, represent executable instructions that cause a computer, processor, and/or other logic device to respond, to perform an action, to change states, to generate an output or display, and/or to make decisions. 
     The various disclosed elements of apparatuses and systems and steps of methods disclosed herein are not required to all apparatuses, systems, and methods according to the present disclosure, and the present disclosure includes all novel and non-obvious combinations and subcombinations of the various elements and steps disclosed herein. Moreover, one or more of the various elements and steps disclosed herein may define independent inventive subject matter that is separate and apart from the whole of a disclosed apparatus, system, or method.
