Description:
BACKGROUND 
     Technical Field 
     This disclosure relates generally to sensor shift flexure arrangements for improved signal routing. 
     Description of the Related Art 
     The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some small form factor cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by the image sensor. In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera.

     This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure. 
     “Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . .” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.). 
     “Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112(f) for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks. 
     “First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value. 
     “Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B. 
     It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact. 
     The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     DETAILED DESCRIPTION 
     Various embodiments include sensor shift flexure arrangements for improved signal routing, e.g., in cameras with sensor shift actuation. For example, a camera system may include a lens group, an image sensor package, a flexure (which may include one or more aspects of the sensor shift flexure arrangements disclosed herein), and/or a flex circuit. Furthermore, the camera system may include one or more actuators (e.g., voice coil motor (VCM) actuator(s)). In some embodiments, the actuator(s) may be used to move the image sensor package relative to the lens group to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. In various embodiments, the flexure may be used to suspend the image sensor package (e.g., from a base structure of the camera system) and to allow motion of the image sensor package enabled by the actuator(s). In some embodiments, the flexure may be coupled with the image sensor package and the flex circuit. The flexure may be configured to convey electrical signals between the image sensor package and the flex circuit. Furthermore, the flex circuit may be configured to convey electrical signals between the flexure and one or more external components that are external to the camera module. 
     In various embodiments, the flexure may include a stack of layers that are arranged so as to improve signal routing, relative to other camera systems that are arranged differently. As an example, the flexure may include a conductive layer and a ground layer. In some aspects, an insulating layer may be positioned between the conductive layer and the ground layer separating the conductive layer from the ground layer. A first area may be beneath at least a section of a signal pad region of the conductive layer and a second area may be beneath at least a section of a signal trace region of the conductive layer. A distance between the conductive layer and the ground layer at the first area may greater than a distance between conductive layer and the ground layer at the second area. The greater distance at the first area relative to the second area may increase the impedance of the signal pad region to a target impedance that is closer to the impedance of the signal trace region. 
     As yet another example, the flexure may additionally or alternatively include an impedance adjusting feature configured to increase the impedance of the electrical signal pad to a target impedance that is closer to the impedance of a signal trace, relative to an impedance of the electrical signal pad if the flexure did not include the impedance adjusting feature. In some embodiments, the impedance adjusting feature may comprise (i) a void or (ii) a cavity that is at least partially filled with an insulating material (e.g., epoxy). 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
       FIG.  1    illustrates a schematic block diagram of an example camera system  100  that may include a sensor shift flexure arrangement for improved signal routing in according to some aspects. According to various embodiments, the camera system  100  may include a lens group  102 , an image sensor package  104 , a flexure  106  (which may include sensor shift flexure arrangement), and/or a flex circuit  108 . Furthermore, the camera system  100  may include one or more actuators (e.g., voice coil motor (VCM) actuator(s), as discussed herein with reference to  FIG.  16   ). The lens group  102  may include one or more lens elements that define an optical axis  110 . Additionally, or alternatively, the camera system  100  may have an optical axis that is orthogonal to an image plane defined by an image sensor (e.g., image sensor  704  in  FIG.  16   ) in the image sensor package  104 . The image sensor may receive light that has passed through the lens group  102  and/or one or more other lens elements of the camera system  100 . Furthermore, the image sensor may be configured to convert the captured light to image signals. 
     In various embodiments, the actuator(s) may be configured to move the image sensor package  104  (also referred to herein as “sensor shift actuation”) and/or the lens group  102 . For example, the actuator(s) may be used to move the image sensor package  104  relative to the lens group  102  to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. For example, the actuator(s) may be used to shift the image sensor package  104  in at least one direction parallel to the optical axis (e.g., in the Z-axis direction), to provide AF functionality in some embodiments. Additionally, or alternatively, the actuator(s) may be used to shift the image sensor package  104  in directions orthogonal to the optical axis  110  (e.g., in the x-axis and/or Y-axis directions), to provide OIS functionality in some embodiments. Additionally, or alternatively, the actuator(s) may be used to move the lens group  102  relative to the image sensor package  104  to provide AF and/or OIS functionality. 
     As further discussed with reference to  FIGS.  2  and  3 A , the flexure  106  may be used to suspend the image sensor package  104  (e.g., from a base structure of the camera system  100 ) and to allow motion of the image sensor package  104  enabled by the actuator(s). In some embodiments, the flexure  106  may be coupled with the image sensor package  104  and the flex circuit  108 , e.g., as indicated in  FIG.  1   . As discussed with reference to  FIGS.  3 A and  3 B , flexure  106  may be configured to convey electrical signals between the image sensor package  104  and the flex circuit  108 . Furthermore, the flex circuit  108  may be configured to convey electrical signals between the flexure  106  and one or more external components  112  that are external to the camera module. 
     In various embodiments, the flexure  106  may include a stack of layers that are arranged so as to improve signal routing, relative to other systems (e.g., camera systems) that are arranged differently. As an example, the flexure  106  may include a first area beneath a signal pad region (e.g., including one or more signal pads) that has a greater distance to a grounding layer than a second area beneath of signal trace region (e.g., including one or more signal traces), which may increase the impedance of the signal pad region (e.g., at least one signal pad) to a target impedance that is closer to the impedance of the signal trace region (e.g., at least one signal trace), relative to an impedance of the signal pad region (e.g., the at least one signal pad) if the insulating layer did not include the increased distance at the first area, as similarly described herein with reference to  FIGS.  4 - 9 ,  13 , and  14   . 
     As another example, the flexure  106  may additionally or alternatively include an impedance adjusting feature also configured to increase the impedance of the signal pad region (e.g., one or more signal pads) to a target impedance that is closer to the impedance of the signal trace region (e.g., one or more signal traces), relative to an impedance of the signal pad region (e.g., at least one signal pad) if the flexure did not include the impedance adjusting feature. In some embodiments, the impedance adjusting feature may comprise (i) a void or (ii) a cavity that is at least partially filled with an insulating material (e.g., epoxy), e.g., as similarly discussed herein with reference to  FIGS.  13 - 15   . 
       FIG.  2    illustrates a top view of example sensor shift flexure  106  that may include a sensor shift flexure arrangement for improved signal routing according to some aspects. In various embodiments, the flexure  106  may include an inner frame  202 , an outer frame  204 , and/or one or more flexure arms  206 . The inner frame  202  may be fixedly coupled with the image sensor (e.g., via the image sensor package  104 ). In some embodiments, the image sensor package  104  may include a substrate (e.g., substrate  310  in  FIGS.  3 A and  3 B , substrate  1612  in  FIG.  16   , etc.) to which the image sensor is fixedly attached, and the substrate may be fixedly attached to the inner frame  202 . The outer frame  204  may at least partially encircle the inner frame  202 . The outer frame  204  may be fixedly coupled with a stationary structure (e.g., stationary structure  1624  in  FIG.  16   ) of the camera. The flexure arm(s)  206  may be connected to the inner frame  202  and to the outer frame  204 , e.g., as indicated in  FIG.  2   . According to various embodiments, the flexure  106  may include electrical traces on at least a portion of the flexure arm(s)  206 . The electrical traces may be configured to convey electrical signals between the inner frame  202  and the outer frame  204 , and vice-versa. In various embodiments, different patterns of electrical traces may be routed from the inner frame  202  to the outer frame  204 , and/or from the outer frame  204  to a flex circuit (e.g., flex circuit  304  in  FIG.  3 A ). The electrical trace(s) may be insulated (e.g., via a dielectric layer and/or a cover layer) in various embodiments. 
     According to some embodiments, the flexure  106  may include one or more electrical signal pad regions, such as, but not limited to, electrical signal pad region  208  (e.g., comprising electrical signal pad  210 ) on the inner frame  202  and/or electrical signal pad region  212  (e.g., comprising electrical signal pad  214 ) on the outer frame  204 . In various embodiments, electrical traces  216  may be routed on the inner frame  202 , the flexure arm(s)  206 , and/or the outer frame  204 . According to various embodiments, electrical traces  216  may be routed from the electrical signal pads on the inner frame  202  to the electrical signal pads on the outer frame  204 , via the flexure arm(s)  206 . In some embodiments, the electrical signal traces may follow routing paths that correspond to the paths of the flexure arm(s)  206  as they extend from the inner frame  202  to the outer frame  204 . The electrical signal traces may be routed above and/or below the flexure arm(s)  206  in some embodiments. Additionally, or alternatively, the electrical signal traces may be at least partially embedded within the flexure arm(s)  206  in some embodiments. 
       FIGS.  3 A- 3 B  illustrate schematic block diagrams of portions of example cameras that may include a sensor shift flexure arrangement for improved signal routing, in accordance with some embodiments.  FIG.  3 A  shows a portion of an example camera  300   a  including a flexure  302  that is attached to a flex circuit  304 , e.g., via an electrical signal pad  306 .  FIG.  3 B  shows a portion of an example camera  300   b  including a flexure-circuit hybrid structure  308 . In various embodiments, anisotropic conductive film (ACF) bonding may be used to attach components together; however, it should be appreciated that one or more other attachment processes (e.g., a surface-mount technology (SMT) attachment process, a hot bar bonding process, etc.) may additionally, or alternatively, be used for attachment of components in various embodiments. 
     As indicated in  FIGS.  3 A- 3 B , the cameras  300   a  and  300   b  may include a substrate  310  that is bonded to the flexure  302  (in  FIG.  3 A ) or to the flexure-circuit hybrid structure  308  (in  FIG.  3 B ), e.g., via electrical signal pad  312 . The substrate  310  may be bonded to an image sensor (e.g., image sensor  704  in  FIG.  16   ). In some embodiments, the image sensor and/or the substrate  310  may be included in the image sensor package  104  in  FIG.  1   . Instead of bonding a flexure to a flex circuit (as in  FIG.  3 A ), the flexure-circuit hybrid structure  308  may be a single component that integrates structural and/or functional aspects of the flexure and the flex circuit, thus eliminating the need for the electrical signal pad  312  ( FIG.  3 A ). 
     In camera  300   a , the flex circuit  304  may be bonded to one or more external components  314 , e.g., via electrical signal pad  316 . The flexure-circuit hybrid structure  308  in camera  300   b  may be bonded to external component(s)  314 , e.g., via electrical signal pad  316 . In  FIGS.  3 A- 3 B , the components (and/or portions of components) within broken rectangle  318  may be located within the corresponding camera module, while the components (and/or portions of components) outside of the broken rectangle  318  may be considered external to the camera module. The exterior component(s)  314  bonded to the flex circuit  304  ( FIG.  3 A ) or to the flexure-circuit hybrid structure  308  ( FIG.  3 B ) are shown as being outside of the broken rectangle  318  to indicate that the external component(s)  314  are external to the corresponding camera module. 
     Electrical signals may be routed between the image sensor and the external component(s)  314  at least partly via the flexure  302  ( FIG.  3 A ) or the flexure-circuit hybrid structure  308  ( FIG.  3 B ). For example, electrical signals may be routed along a path that includes the image sensor, an electrical signal pad for interconnecting the image sensor with the substrate  310 , the substrate  310 , electrical signal pad  312 , the flexure  302  ( FIG.  3 A ) or the flexure-circuit hybrid structure  308  ( FIG.  3 B ), electrical signal pad  306  ( FIG.  3 A ), the flex circuit  304  ( FIG.  3 A ), electrical signal pad  316 , and the external component(s)  314 , in that order from the image sensor to the external component(s)  314 , and/or vice-versa. Additionally, or alternatively, the camera  300   a  may include a via  320  that is used to route electrical signals from one side (e.g., a bottom side) of the flex circuit  304  to the opposite side (e.g., a top side) of the flex circuit  304 . 
       FIG.  4    illustrates a schematic diagram of an example sensor shift flexure arrangement  400  for improved signal routing according to some aspects. As shown in  FIG.  4   , the example sensor shift flexure arrangement  400  may include layers of material that are stacked in a direction orthogonal to an image plane of an image sensor (e.g., the image sensor included in the image sensor package  104  in  FIG.  1   , image sensor  1604  in  FIG.  16   , etc.). According to various embodiments, the stack-up of layers may include a base layer  402 , a dielectric layer  408 , a seed layer  410 , and/or a conductive layer  412 . In some aspects, an adhesion layer may be positioned between the dielectric layer  408  and the base layer  402 . 
     Furthermore, the sensor shift flexure arrangement  400  may include a one or more signal pad regions  414  including, for example, a first signal pad region  414   a  and a second signal pad region  414   b . In some aspects, at least one signal pad in a signal pad region may be at least one of a higher-speed signal pad, an electroless nickel immersion gold (ENIG) pad, or the like. In some embodiments, one or more portions of the sensor shift flexure arrangements  400  may include a cover layer  416  (e.g., polyimide (PI), a hybrid-style PI and adhesive material provided as a laminated cover layer, etc.), such as the one positioned, in a direction parallel to the image plane, between first signal pad region  414   a  and the second signal pad region  414   b . In some embodiments, the cover layer  416  may cover conductive layer  412  in certain portions of the flexure, e.g., such that the covered portions of conductive layer  412  are sandwiched between the cover layer  416  and one or more other layers (e.g., the seed layer  410 ). 
     In some aspects, the base layer  402  may form at least a portion of an electrical grounding portion  418  (which may comprise a reference plane). The dielectric layer  408  may form at least a portion of an intermediate portion  420 . The seed layer  410 , the conductive layer  412  and/or the one or more signal pad regions  414  may form at least a portion of a signal trace interconnect portion  422  that may be used to interconnect signal traces on the flexure with one or more other components, e.g., as discussed herein with reference to  FIGS.  1 - 3 B . 
     In some embodiments, the signal trace interconnect portion  422  may be located at the inner frame (e.g., inner frame  202  in  FIG.  2   ) and/or the outer frame (e.g., outer frame  204  in  FIG.  2   ) of the flexure. As a non-limiting example, the signal trace interconnect portion  422  may be located in electrical signal pad region  208  indicated in  FIG.  2   . For example, the one or more signal pad regions  414  may include an electrical signal pad used for connecting the inner frame of the flexure with an image sensor substrate (and/or another component of the image sensor package), e.g., as does electrical signal pad  312  with respect to connecting flexure  302  to substrate  310  in  FIG.  3 A . As another non-limiting example, the signal trace interconnect portion  422  may be located in electrical signal pad region  212  indicated in  FIG.  2   . For example, the one or more signal pad regions  414  may include an electrical signal pad used for connecting the outer frame of the flexure with a flex circuit (and/or one or more other components), e.g., as does electrical signal pad  306  with respect to connecting flexure  302  to flex circuit  304  in  FIG.  3 A . 
     In various embodiments, the one or more signal pad regions  414  may be constrained to a relatively large size of width and/or length by the type of process(es) used for attaching the flexure with other component(s). Non-limiting examples of attachment processes may include an ACF bonding process, an SMT attachment process, and/or a hot bar bonding process, etc. The large size of the one or more signal pad regions  414  and/or one or more signal pads of the one or more signal pad regions  414  may cause the one or more signal pad regions  414  and/or the one or more signal pads of the one or more signal pad regions  414  to have a relatively low impedance which may result in poor channel performance for electrical signals (e.g., higher-speed signals) when there is a mismatch between the impedance of the one or more signal pad regions  414  and/or the one or more signal pads of the one or more signal pad regions  414  and the corresponding signal channel(s) (e.g., the electrical signal trace(s) formed by the conductive layer  412 ). 
     As shown in  FIG.  4   , the signal trace interconnect portion  422  may include at least a first area  424  and a second area  426 . The first area  424  may be a surface of the signal trace interconnect portion  422  that is adjacent (e.g., abutting, next to) at least a portion of the intermediate portion  420 . For example, as shown in  FIG.  4   , the first area  424  may be adjacent at least a portion of the dielectric layer  408 . The second area  426  may be another surface of the signal trace interconnect portion  422  that is adjacent (e.g., abutting, next to) at least another portion of the intermediate portion  422 . For example, as shown in  FIG.  4   , the second area  426  may be a surface of the cover layer  416 . In some aspects, the second area  426  may be a surface aligned with one or more electrical traces (e.g., electrical traces  216  illustrated in  FIG.  2   ), for example, embedded within the cover layer  416 . Additionally, or alternatively, the second area  426  may be adjacent (e.g., aligned with) the dielectric layer  408 . 
     In some aspects, the first area  424  may be beneath (e.g., aligned with, a lower surface of) at least a portion of the first signal pad region  414   a . For example, the first area  424  may be beneath the first signal pad region  414   a  and positioned along an axis that is perpendicular to the first area  424  and intersects with the first signal pad region  414   a . In some aspects, the first area  424  may be beneath the entire first signal pad region  414   a . Additionally, or alternatively, the first area  424  may be beneath one or more signal pads disposed on and/or in the first signal pad region  414   a  and/or not beneath a remainder of the first signal pad region  414   a.    
     The second area  426  may be beneath (e.g., aligned with, a lower surface of) at least a portion of the cover layer  416 . For example, the second area  426  may be beneath the cover layer  416  and positioned along an axis that is perpendicular to the second area  426  and intersects with the cover layer  416 . In some aspects, the cover layer  416  may be beneath or may embedded one or more electrical traces (e.g., electrical traces  216  illustrated in  FIG.  2   ) routed on an inner frame (e.g., the inner frame  202  illustrated in  FIG.  2   ), one or more flexure arms (e.g., flexure arm(s)  206  illustrated in  FIG.  2   ), and/or an outer frame (e.g., the outer frame  204  illustrated in  FIG.  2   ) and/or not beneath a remainder of the cover layer  416 . For example, the second area  426  may be beneath one or more signal traces aligned with the cover layer  416 . 
     When, for example, a dielectric layer has a substantially similar depth (e.g., a same depth) across signal pad region(s) (e.g., one or more signal pads) and a cover layer (e.g., one or more signal traces at a same elevation as the one or more signal pads), the distance between the signal pads and the base layer and the distance between the signal traces (e.g., located within the cover layer) and base layer may be substantially similar. In this case, the impedance at the signal traces may be greater than the impedance at the one or more signal pads creating channel return loss and less signal integrity. Conversely, if, for example, a dielectric layer has varying depths such that, for example, a depth of the dielectric layer beneath a signal pad region (e.g., one or more signal pads) is greater than a depth of the dielectric layer beneath a cover layer (e.g., one or more electrical traces), the additional depth of the dielectric layer beneath the signal pad region may increase the distance between signal pad region and the base layer (e.g., compared to the distance between the one or more electrical traces and the base layer) and increase the impedance of the signal pad region to better match a target channel impedance (e.g., an impedance at the electrical traces) enabling time domain reflectometry (TDR) improvements. Better matching pad impedance to the channel impedance may help reduce channel return loss. Reducing channel return loss may improve signal integrity. Improving signal integrity may enable a higher bandwidth for the channel. Furthermore, improving signal integrity may help reduce system power consumption, e.g., by reducing signal/power transmitter swing and/or optimizing signal/power receiver equalization needs. 
     As shown in  FIG.  4   , the signal trace interconnect portion  422  includes the first area  424 , that is aligned with the first signal pad region  414   a  (e.g., one or more signal pads) and is aligned with a region of the base layer  402  forming a greater distance between the first signal pad region  414   a  and the base layer  402  than a region of the signal trace interconnect portion  422  at the second area  426 , that is aligned with the cover layer  416  (e.g., one or more electrical traces). The greater depth of the dielectric layer  408  at (e.g., beneath) the first area  424  and/or the greater height of the base layer  402  may provide a greater distance between the first signal pad region  414   a  and the base layer  402  and may cause the impedance at the first signal pad region  414   a  to be relatively closer to (e.g., substantially similar to, substantially the same as, the same as) the impedance at the cover layer  416  (e.g., one or more electrical traces). For example, as shown in  FIG.  4   , the base layer  402  includes at least two different thicknesses: a first thickness beneath the first area  424  of the signal trace interconnect portion  422  and a second thickness beneath the second area  426  of the signal trace interconnect portion  422 . The first thickness may be less than the second thickness so that a distance between the first signal pad region  414   a  and the base layer  402  (e.g., through the dielectric layer  408 ) is greater than a distance between the cover layer  416  (e.g., one or more signal traces on and/or within the cover layer  416 ) and the base layer  402  (e.g., through the dielectric layer  408 ). 
     It should be understood that greater the distance between the first signal pad region  414   a  and the base layer  402 , the greater the impedance at the first signal pad region  414   a . Thus, distance between the first signal pad region  414   a  (e.g., one or more signal pads) and the base layer  402  may be set to a target distance to achieve a target impedance so that the impedance at the first signal pad region  414   a  (e.g., at least one signal pad at the first signal pad region  414   a ) is at least similar to or the same as the impedance at the cover layer  416  (e.g., at least one electrical trace aligned with the cover layer  416 ). 
     In some aspects, the signal trace interconnect portion  422  may include at least a first area  424  and a second area  426 . The first area  424  may be a surface of the signal trace interconnect portion  422  that is adjacent (e.g., abutting, next to) at least a portion of the intermediate portion  420 . For example, as shown in  FIG.  4   , the first area  424  may be adjacent at least a portion of the dielectric layer  408 . The second area  426  may be another surface of the signal trace interconnect portion  422  that is adjacent (e.g., abutting, next to) at least another portion of the intermediate portion  422 . For example, as shown in  FIG.  4   , the second area  426  may be a surface of the cover layer  416 . In some aspects, the second area  426  may be a surface aligned with one or more electrical traces (e.g., electrical traces  216  illustrated in  FIG.  2   ), for example, embedded within the cover layer  416 . Additionally, or alternatively, the second area  426  may be adjacent (e.g., aligned with) the dielectric layer  408 . 
     In some aspects, the first area  424  may be beneath (e.g., aligned with, a lower surface of) at least a portion of the first signal pad region  414   a . For example, the first area  424  may be beneath the first signal pad region  414   a  and positioned along an axis that is perpendicular to the first area  424  and intersects with the first signal pad region  414   a . In some aspects, the first area  424  may be beneath the entire first signal pad region  414   a . Additionally, or alternatively, the first area  424  may be beneath one or more signal pads disposed on and/or in the first signal pad region  414   a  and/or not beneath a remainder of the first signal pad region  414   a.    
     As shown in  FIG.  4   , the signal trace interconnect portion  422  includes the third area  428 , that is aligned with the second signal pad region  414   b  (e.g., one or more signal pads) and is aligned with a region of the dielectric layer  408  that has a greater depth to the base layer  402  than a region of the dielectric layer  408  at the second area  426 , that is aligned with the cover layer  416  (e.g., one or more electrical traces). The greater depth of the dielectric layer  408  at (e.g., beneath) the third area  428  may provide a greater distance between the second signal pad region  414   b  and the base layer  402  and may cause the impedance at the second signal pad region  414   b  to be relatively closer to (e.g., substantially similar to, substantially the same as, the same as) the impedance at the cover layer  416  (e.g., one or more electrical traces). It should be understood that the distance between the second signal pad region  414   b  and the base layer  402 , the greater the impedance at the second signal pad region  414   b . Thus, the depth of the dielectric layer  408  beneath the third area  428  and/or the distance between the second signal pad region  414   b  (e.g., one or more signal pads) and the base layer  402  may be set to a target depth or distance to achieve a target impedance so that the impedance at the second signal pad region  414   b  (e.g., at least one signal pad at the second signal pad region  414   b ) is at least similar to or the same as the impedance at the cover layer  416  (e.g., at least one electrical trace aligned with the cover layer  416 ). For example, as shown in  FIG.  4   , the base layer  402  includes different thicknesses: a first thickness beneath the first area  424  of the dielectric layer  408 , a second thickness beneath the second area  426  of the signal trace interconnect portion  422 , and a third thickness beneath the third area  428  of the signal trace interconnect portion  422 . The first thickness and the third thickness may be less than the second thickness so that a distance between the first signal pad region  414   a  and the base layer  402  and the second signal pad region  414   b  and the base layer  402  are both greater than a distance between the cover layer  416  and the base layer  402 . 
     In some aspects, when a difference in impedance between the first signal pad region  414   a  and the cover layer  416  is at least the same as or at least similar to a difference in impedance between the second signal pad region  414   b  and the cover layer  416 , then the distance between the second signal pad region  414   b  and the base layer  402  (e.g., a depth of the dielectric layer  408  at the third area  428 ) may be the same as or at least similar to distance between the first signal pad region  414   a  and the base layer  402  (e.g., a depth of the dielectric layer  408  at the first area  424 ). In some aspects, when a difference in impedance between the first signal pad region  414   a  and the cover layer  416  is a first impedance difference and a difference in impedance between the second signal pad region  414   b  and the cover layer  416  is a second and different impedance difference, then the distance between the first signal pad region  414   a  and the base layer  402  may be a different distance than the distance between the second signal pad region  414   b  and the base layer  402 . For example, when the first impedance difference is greater than the second impedance difference, then the distance between the first signal pad region  414   a  and the base layer  402  (e.g., a depth of the dielectric layer  408  at the first area  424 ) may be greater than a distance between the second signal pad region  414   b  and the base layer  402  (e.g., a depth the dielectric layer  408  at the third area  428 ). As another example, when the first impedance difference is less than the second impedance difference, then the distance between the first signal pad region  414   a  and the base layer  402  (e.g., a depth of the dielectric layer  408  at the first area  424 ) may be less than the distance between the second signal pad region  414   b  and the base layer  402  (e.g., a depth the dielectric layer  408  at the third area  428 ). 
       FIG.  5    illustrates a schematic diagram of another example sensor shift flexure arrangement  500  for improved signal routing according to some aspects. The sensor shift flexure arrangement  500  may include one or more same or similar features as camera system  100  of  FIG.  1   , the sensor shift flexure  106  of  FIG.  2   , the camera  300   a  of  FIG.  3 A , the camera  300   b  of  FIG.  3 B , and/or the sensor shift flexure arrangement  400  of  FIG.  4   . For example, the sensor shift flexure arrangement  500  may include a base layer  502 , a dielectric layer  508 , a seed layer  510 , a conductive layer  512 , one or more signal pad regions  514  including a first signal pad region  514   a  and a second signal pad region  514   b , a cover layer  516 . The sensor shift flexure arrangement  500  may also include an electrical grounding portion/reference plane  518  having at least the base layer  502 , an intermediate portion  520  having at least the adhesion layer  506  and the dielectric layer  508 , and/or a signal trace interconnect portion  522  having at least the seed layer  510 , the conductive layer  512 , the one or more signal pad regions  514 , and the cover layer  516 . In some aspects, an adhesion layer may be positioned between the dielectric layer  508  and the base layer  502 . 
     As shown in  FIG.  5    and at least similar to the sensor shift flexure arrangement  400  illustrated in  FIG.  4   , the distance between the first signal pad region  514   a  and the base layer  502  and the distance between the second signal pad region  514   b  and the base layer  502  may be greater than a distance between the cover layer  516  and the base layer  502 . For example, the distance between the first signal pad region  514   a  and the base layer  502  and the distance between the second signal pad region  514   b  and the base layer  502  may be greater than a distance between the cover layer  516  and the base layer  502  due to the dielectric layer  508  at the first area  524  and/or the dielectric layer  508  at the third area  528  having a greater depth than the dielectric layer  508  at a second area  526 . The greater the distance between the first signal pad region  514   a  and the base layer  502 , the greater the impedance at the first signal pad region  514   a . For example, the distance between the first signal pad region  514   a  (e.g., one or more signal pads) and the base layer  502  (e.g., the depth of the dielectric layer  508  beneath the first area  524 ) may be set to a target distance to achieve a target impedance so that the impedance at the first signal pad region  514   a  (e.g., at least one signal pad at the first signal pad region  514   a ) is at least similar to or the same as the impedance at the cover layer  516  (e.g., at least one electrical trace aligned with the cover layer  516 ). Similarly, the distance between the second signal pad region  514   b  (e.g., one or more signal pads) and the base layer  502  may be set to a target depth or distance to achieve a target impedance so that the impedance at the second signal pad region  514   b  (e.g., at least one signal pad at the second signal pad region  514   b ) is at least similar to or the same as the impedance at the cover layer  516  (e.g., at least one electrical trace aligned with the cover layer  516 ). In this example, the sensor shift flexure arrangement  500 , due to the increased thickness of the dielectric layer  508  beneath the first area  524  and the third area  528 , may have a greater height at the first signal pad region  514   a  and at the second signal pad region  514   b  compared to the cover layer  516 . 
       FIG.  6    illustrates a schematic diagram of yet another example sensor shift flexure arrangement  600  for improved signal routing according to some aspects. The sensor shift flexure arrangement  600  may include one or more same or similar features as camera system  100  of  FIG.  1   , the sensor shift flexure  106  of  FIG.  2   , the camera  300   a  of  FIG.  3 A , the camera  300   b  of  FIG.  3 B , the sensor shift flexure arrangement  400  of  FIG.  4   , and/or the sensor shift flexure arrangement  500  of  FIG.  5   . For example, the sensor shift flexure arrangement  600  may include a base layer  602 , an adhesion layer  606 , a dielectric layer  608 , a seed layer  610 , a conductive layer  612 , one or more signal pad regions  614  including a first signal pad region  614   a  and a second signal pad region  614   b , a cover layer  616 . The sensor shift flexure arrangement  600  may also include an electrical grounding portion/reference plane  618  having at least the base layer  602 , an intermediate portion  620  having at least the adhesion layer  606  and the dielectric layer  608 , and/or a signal trace interconnect portion  622  having at least the seed layer  610 , the conductive layer  612 , the one or more signal pad regions  614 , and the cover layer  616 . In some aspects, an adhesion layer may be positioned between the dielectric layer  608  and the base layer  602 . 
     As shown in  FIG.  6    and at least similar to the sensor shift flexure arrangement  400  illustrated in  FIG.  4    and the sensor shift flexure arrangement  500  illustrated in  FIG.  5   , the distance between the first signal pad region  614   a  and the base layer  602  and the distance between the second signal pad region  614   b  and the base layer  602  may be greater than a distance between the cover layer  616  and the base layer  602 . For example, the distance between the first signal pad region  614   a  and the base layer  602  and the distance between the second signal pad region  614   b  and the base layer  602  may be greater than a distance between the cover layer  616  and the base layer  602  due to the dielectric layer  608  at the first area  624  and/or the dielectric layer  608  at the third area  628  having a greater depth than the dielectric layer  608  at a second area  626 . The greater the distance between the first signal pad region  614   a  and the base layer  602 , the greater the impedance at the first signal pad region  614   a . For example, the distance between the first signal pad region  614   a  (e.g., one or more signal pads) and the base layer  602  (e.g., the depth of the dielectric layer  608  beneath the first area  624 ) may be set to a target distance to achieve a target impedance so that the impedance at the first signal pad region  614   a  (e.g., at least one signal pad at the first signal pad region  614   a ) is at least similar to or the same as the impedance at the cover layer  616  (e.g., at least one electrical trace aligned with the cover layer  616 ). Similarly, the distance between the second signal pad region  614   b  (e.g., one or more signal pads) and the base layer  602  may be set to a target depth or distance to achieve a target impedance so that the impedance at the second signal pad region  614   b  (e.g., at least one signal pad at the second signal pad region  614   b ) is at least similar to or the same as the impedance at the cover layer  616  (e.g., at least one electrical trace aligned with the cover layer  616 ). 
     In the example of  FIG.  6   , the base layer  602  includes different thicknesses: a first thickness beneath the first area  624  of the dielectric layer  608 , a second thickness beneath the second area  626  of the dielectric layer  608 , and a third thickness beneath the third area  628  of the dielectric layer  608 . The first thickness and the third thickness may be less than the second thickness so that a distance between the first signal pad region  614   a  and the base layer  602  and the second signal pad region  614   b  and the base layer  602  are both greater than a distance between the cover layer  616  and the base layer  602 . In addition, the sensor shift flexure arrangement  600 , due to the increased thickness of the dielectric layer  608  beneath the first area  624  and the third area  628 , may have a greater height at the first signal pad region  614   a  and at the second signal pad region  614   b  compared to the cover layer  616  so that a distance between the first signal pad region  614   a  and the base layer  602  and the second signal pad region  614   b  and the base layer  602  are both greater than a distance between the cover layer  616  and the base layer  602 . 
       FIG.  7    illustrates a schematic diagram of another example sensor shift flexure arrangement  700  for improved signal routing according to some aspects. The sensor shift flexure arrangement  700  may include one or more same or similar features as camera system  100  of  FIG.  1   , the sensor shift flexure  106  of  FIG.  2   , the camera  300   a  of  FIG.  3 A , the camera  300   b  of  FIG.  3 B , the sensor shift flexure arrangement  400  of  FIG.  4   , the sensor shift flexure arrangement  500  of  FIG.  5   , and/or the sensor shift flexure arrangement  600  of  FIG.  6   . For example, the sensor shift flexure arrangement  700  may include a base layer  702 , a dielectric layer  708 , a seed layer  710 , a conductive layer  712 , and a signal pad region  714 .

As shown in  FIG.  7   , the intermediate portion  720  may include at least a first area  724  of the signal trace interconnect portion  722 . Similar to the signal trace interconnect portion  422  in  FIG.  4   , the signal trace interconnect portion  522  in  FIG.  5   , and/or the signal trace interconnect portion  622  illustrated in  FIG.  6   , the signal trace interconnect portion  722  may also include at least a second area and/or a third area as described herein. 
     Also, as shown in  FIG.  7   , the base layer  702  may have different heights beneath the first area  724  varying the distance between the first signal pad region  726  and the base layer  702 . For example, a first indented section  725   a , a second indented section  725   c , a third indented section  725   e , a fourth indented section  725   g , a fifth indented section  725   i , and a sixth indented section  725   k  each of the base layer  702  beneath the first area  724  may provide a greater distance between the first signal pad region  714  and the base layer  702  than a first extended section  725   b , a second extended section  725   d , a third extended section  725   f , a fourth extended section  725   h , a fifth extended section  725   j , and a sixth extended section  725   l  each also of the base layer  702  beneath the first area  724 . 
     In some aspects, the signal pad region  714  may include one or more signal pad region slots  726 . The one or more signal pad region slots  726  may include at least one signal pad region slot for a higher-speed signal pad. For example, as shown in  FIG.  7   , the one or more signal pad region slots  726  may include a first higher-speed signal pad slot  726   a , a second higher-speed signal pad slot  726   c , a third higher-speed signal pad slot  726   e , a fourth higher-speed signal pad slot  726   g , a fifth higher-speed signal pad slot  726   i , and a sixth higher-speed signal pad slot  726   k .

     Additionally, or alternatively, the one or more signal pad region slots  726  may include at least one signal pad region slot for a lower-speed signal pad. For example, the one or more signal pad region slots  726  may include a first lower-speed signal pad slot  726   b , a second lower-speed signal pad slot  726   d , a third lower-speed signal pad slot  726   f , a fourth lower-speed signal pad slot  726   h , a fifth lower-speed signal pad slot  726   j , and a sixth lower-speed signal pad slot  726   l .

The higher-speed signal pad slots and the lower-speed signal pad slots may be arranged in an alternating pattern within the signal pad region  714 . As described further here, the higher-speed signal pad slots and the lower-speed signal pad slots may be grouped together, as described further herein, and/or may be arranged in an alternating group pattern within the signal pad region  714 . In some aspects, the higher-speed signal pad slots and the lower-speed signal pad slots may be arranged randomly or according to one or more specified arrangements. 
     As shown in  FIG.  7   , the first indented section  725   a , the second indented section  725   c , the third indented section  725   e , the fourth indented section  725   g , the fifth indented section  725   i , and the sixth indented section  725   k  of the base layer  702  beneath the first area  724  may be vertically aligned with the first higher-speed signal pad slot  726   a , the second higher-speed signal pad slot  726   c , the third higher-speed signal pad slot  726   e , the fourth higher-speed signal pad slot  726   g , the fifth higher-speed signal pad slot  726   i , and the sixth higher-speed signal pad slot  726   k  of the signal pad region  714 , respectively. Similarly, the first extended section  725   b , the second extended section  725   d , the third extended section  725   f , the fourth extended section  725   h , the fifth extended section  725   j , and the sixth extended section  725   l  of the base layer  702  beneath the first area  724  may be vertically aligned with the first lower-speed signal pad slot  726   b , the second lower-speed signal pad slot  726   d , the third lower-speed signal pad slot  726   f , the fourth lower-speed signal pad slot  726   h , the fifth lower-speed signal pad slot  726   j , and the sixth lower-speed signal pad slot  726   l  of the signal pad region  714 , respectively. 
     When a distance between one or more higher-speed signal pads and a base layer and a distance between one or more signal traces associated with the one or more higher-speed signal pads and the base layer is substantially similar (e.g., a same distance), the impedance at the one or more signal traces associated with the one or more higher-speed signal pads may be greater than the impedance at the higher-speed signal pad region slots creating channel return loss and less signal integrity. Conversely, if a base layer has varying heights such that, for example, a first height of the base layer beneath one or more higher-speed signal pad region slots (e.g., one or more higher-speed signal pads) is lower than a height of the base layer beneath a cover layer (e.g., one or more signal traces associated with the one or more higher-speed signal pads), a distance between the higher-speed signal pad region slots and the base layer that is greater than a distance between the one or more signal traces associated with the higher-speed signal pad region slots and the base layer may increase the impedance of the higher-speed signal pads to better match a target channel impedance (e.g., an impedance at the higher-speed signal traces) enabling time domain reflectometry (TDR) improvements. Better matching pad impedance to the channel impedance may help reduce channel return loss. Reducing channel return loss may improve signal integrity. Improving signal integrity may enable a higher bandwidth for the channel. Furthermore, improving signal integrity may help reduce system power consumption, e.g., by reducing signal/power transmitter swing and/or optimizing signal/power receiver equalization needs. 
     Similarly, when a distance between one or more lower-speed signal pads and a base layer and a distance between one or more signal traces associated with the one or more lower-speed signal pads and the base layer is substantially similar (e.g., a same distance), the impedance at the one or more signal traces associated with the one or more lower-speed signal pads may be greater than the impedance at the lower-speed signal pad region slots creating channel return loss and less signal integrity. Conversely, if a base layer has varying heights such that, for example, a second height of the base layer beneath one or more lower-speed signal pad region slots (e.g., one or more lower-speed signal pads) is lower than a height of the base layer beneath a cover layer (e.g., one or more signal traces associated with the one or more lower-speed signal pads), a distance between the lower-speed signal pad region slots and the base layer that is greater than a distance between the one or more signal traces associated with the lower-speed signal pad region slots and the base layer may increase the impedance of the lower-speed signal pads to better match a target channel impedance (e.g., an impedance at the lower-speed signal traces) enabling time domain reflectometry (TDR) improvements. Better matching pad impedance to the channel impedance may help reduce channel return loss. Reducing channel return loss may improve signal integrity. Improving signal integrity may enable a higher bandwidth for the channel. Furthermore, improving signal integrity may help reduce system power consumption, e.g., by reducing signal/power transmitter swing and/or optimizing signal/power receiver equalization needs. 
     It should be understood that an impedance difference between the impedance from the higher-speed signal pads to the base layer and the impedance from the signal traces associated with the higher-speed signal pads to the base layer may be greater than an impedance difference between the impedance from the lower-speed signal pads to the base layer and the impedance from signal traces associated with the higher-speed signal pads to the base layer. Thus, in order to match impedances associated with higher-speed signal pads, signal traces associated with the higher-speed signal pads, lower-speed signal pads, and signal traces associated with lower-speed signal pads, the distance between the lower-speed signal pads and the base layer may be greater than a distance between the signal traces associated with the lower-speed signal pad and the base layer and a distance between the signal traces associated with the higher-speed signal pads and the base layer, but less than a distance between the higher-speed signal pads and the base layer. In some aspects, the distance between the lower-speed signal pads and the base layer may less than the distance between the higher-speed signal pads and the base layer, but equal to the distance between the signal traces associated with the higher-speed signal traces and/or equal to the distance between the signal traces associated with the lower-speed signal pads and the base layer.

As shown in FIG.  8 , the intermediate portion  820  may include at least a first area  824  of the signal trace interconnect portion  822 . Similar to the dielectric layer  408  in  FIG.  4   , the dielectric layer  508  in  FIG.  5   , and/or the dielectric layer  608  illustrated in  FIG.  6   , the dielectric layer  808  may also include at least a second area and a third area as described herein. 
     As previously discussed herein, the higher-speed signal pad slots and the lower-speed signal pad slots may be arranged in an alternating pattern within the signal pad region. As described herein at least with respect to  FIG.  8   , the higher-speed signal pad slots and the lower-speed signal pad slots may be grouped together. In some aspects, the signal pad region  814  may include one or more signal pad region slots  826 . The one or more signal pad region slots  826  may include at least one signal pad region slot for a higher-speed signal pad. Additionally, or alternatively, the one or more signal pad region slots  826  may include at least one signal pad region slot for a lower-speed signal pad. 
     For example, as shown in  FIG.  8   , the one or more signal pad region slots  826  may include a first higher-speed signal pad slot  826   a , a second higher-speed signal pad slot  826   b , a third higher-speed signal pad slot  826   c , a fourth higher-speed signal pad slot  826   d , a fifth higher-speed signal pad slot  826   e , and a sixth higher-speed signal pad slot  826   f .

Each of the first lower-speed signal pad slot  826   g , the second lower-speed signal pad slot  826   h , the third lower-speed signal pad slot  826   i , the fourth lower-speed signal pad slot  826   j , the fifth lower-speed signal pad slot  826   k , and the sixth lower-speed signal pad slot  826   l  may include a lower-speed signal pad as described herein. As shown in  FIG.  8   , the higher-speed signal pad slots and the lower-speed signal pad slots may be grouped together within the signal pad region  814 . 
     As shown in  FIG.  8   , the indented section  825   a  of the base layer  802  beneath the first area  824  may be vertically aligned with the first higher-speed signal pad slot  826   a , the second higher-speed signal pad slot  826   b , the third higher-speed signal pad slot  826   c , the fourth higher-speed signal pad slot  826   d , the fifth higher-speed signal pad slot  826   e , and the sixth higher-speed signal pad slot  826   f  of the signal pad region  814  grouped together. Similarly, the thicker section  825   b  of the base layer  802  beneath the first area  824  may be vertically aligned with the first lower-speed signal pad slot  826   g , the second lower-speed signal pad slot  826   h , the third lower-speed signal pad slot  826   i , the fourth lower-speed signal pad slot  826   j , the fifth lower-speed signal pad slot  826   k , and the sixth lower-speed signal pad slot  826   l  grouped together.

Conversely, if a base layer has varying heights such that, for example, a first height of the base layer beneath one or more higher-speed signal pad region slots (e.g., one or more higher-speed signal pads) is less than a height of the base layer beneath a cover layer (e.g., one or more signal traces associated with the one or more higher-speed signal pads), a distance between the higher-speed signal pad region slots and the base layer that is greater than a distance between the one or more signal traces associated with the higher-speed signal pad region slots and the base layer may increase the impedance of the higher-speed signal pads to better match a target channel impedance (e.g., an impedance at the higher-speed signal traces) enabling time domain reflectometry (TDR) improvements.

Thus, in order to match impedances associated with higher-speed signal pads, signal traces associated with the higher-speed signal pads, lower-speed signal pads, and signal traces associated with lower-speed signal pads, the distance between the lower-speed signal pads and the base layer may be greater than a distance between the signal traces associated with the lower-speed signal pad and the base layer and a distance between the signal traces associated with the higher-speed signal pads and the base layer, but less than a distance between the higher-speed signal pads and the base layer. In some aspects, the distance between the lower-speed signal pads and the base layer may less than the distance between the higher-speed signal pads and the base layer, but equal to the distance between the signal traces associated with the higher-speed signal traces and/or equal to the distance between the signal traces associated with the lower-speed signal pads and the base layer. 
     As described herein, one or more signal pad regions may be constrained to a relatively large size of width and/or length by the type of process(es) used for attaching the flexure with other component(s). Non-limiting examples of attachment processes may include an ACF bonding process, an SMT attachment process, and/or a hot bar bonding process, etc. The large size of the one or more signal pad regions and/or one or more signal pads of the one or more signal pad regions may cause the one or more signal pad regions and/or the one or more signal pads of the one or more signal pad regions to have a relatively low impedance which may result in poor channel performance for electrical signals (e.g., higher-speed signals) when there is a mismatch between the impedance of the one or more signal pad regions and/or the one or more signal pads of the one or more signal pad regions and the corresponding signal channel(s) (e.g., the electrical signal trace(s) formed by the conductive layer). 
       FIG.  9    illustrates a schematic diagram of another example sensor shift flexure arrangement  900  for improved signal routing according to some aspects.

For example, the sensor shift flexure arrangement  900  may include a base layer  902 , a dielectric layer  908 , a seed layer  910 , a conductive layer  912 , and a signal pad region  914 . The sensor shift flexure arrangement  900  may also include an electrical grounding portion/reference plane  918  having at least the base layer  902 , an intermediate portion  920  having at least the dielectric layer  908 , and/or a signal trace interconnect portion  922  having at least the conductive layer  912  and the signal pad region  914 . As shown in  FIG.  9   , the signal trace interconnect portion  922  may include at least a first area  924 .

     Also, as shown in  FIG.  9   , the base layer  902  may have different heights beneath the first area  924  varying the distance between the first signal pad region  926  and the base layer  902 . For example, a first indented section  925   a , a second indented section  925   b , and a third indented section  925   c  each of the base layer  902  beneath the first area  924  may provide a greater distance between the signal pad region  914  and the base layer  902  than other sections of the base layer  902  beneath the first area  924 . In some aspects, the signal pad region  914  may include one or more signal pad region slots  926 . The one or more signal pad region slots  926  may include at least one signal pad region slot for a higher-speed signal pad. For example, as shown in  FIG.  9   , the one or more signal pad region slots  926  may include a first higher-speed signal pad slot  926   a , a second higher-speed signal pad slot  926   b , and a third higher-speed signal pad slot  926   c .

     Additionally, or alternatively, the one or more signal pad region slots  926  may include at least one signal pad region slot for a lower-speed signal pad. For example, the one or more signal pad region slots  926  may include a first lower-speed signal pad slot  926   d , a second lower-speed signal pad slot  926   e , and a third lower-speed signal pad slot  926   f . Each of the first lower-speed signal pad slot  926   d , the second lower-speed signal pad slot  926   e , and the third lower-speed signal pad slot  926   f  may include a lower-speed signal pad as described herein. The higher-speed signal pad slots and the lower-speed signal pad slots are arranged in an alternating pattern within the signal pad region  914 . As described further here, the higher-speed signal pad slots and the lower-speed signal pad slots may be grouped together, as described further herein, and/or may be arranged in an alternating group pattern within the signal pad region  914 . In some aspects, the higher-speed signal pad slots and the lower-speed signal pad slots may be arranged randomly or according to one or more specified arrangements. 
     As shown in  FIG.  9   , the first indented section  925   a , the second indented section  925   b , the third indented section  925   c  may be vertically aligned with the first higher-speed signal pad slot  926   a , the second higher-speed signal pad slot  926   b , and the third higher-speed signal pad slot  926   c , respectively. Similarly, remaining extended sections of the base layer  902  beneath the first area  924  may be vertically aligned with the first lower-speed signal pad slot  926   d , the second lower-speed signal pad slot  926   e , and the third lower-speed signal pad slot  926   f.

In some aspects, the distance between the lower-speed signal pads and the base layer may less than the distance between the higher-speed signal pads and the base layer, but equal to the distance between the signal traces associated with the higher-speed signal traces and/or equal to the distance between the signal traces associated with the lower-speed signal pads and the base layer. 
     Additionally, or alternatively, the one or more signal pad region slots  926  may include at least one signal pad region slot for a higher-speed signal pad that has a smaller area (e.g., a lesser length and/or a lesser width) than at least one signal pad region slot for a lower-speed signal pad. For example, as shown in  FIG.  9   , the first higher-speed signal pad slot  926   a , the second higher-speed signal pad slot  926   b , and the third higher-speed signal pad slot  926   c  may each comprise a smaller area than the first lower-speed signal pad slot  926   d , the second lower-speed signal pad slot  926   e , and the third lower-speed signal pad slot  926   f . The reduced size of the one or more signal pad region slots for the higher-speed signal pads, for example, compared to the one or more signal pad region slots for the lower-speed signal pads, may increase the impedance at the one or more signal pad region slots for the higher-speed signal pads and may result in improved channel performance for electrical signals (e.g., higher-speed signals) when there is a match between the impedance of the one or more signal pad regions for the higher-speed signal pads and/or the one or more signal pads of the one or more signal pad regions for the higher-speed signal pads and the corresponding signal channel(s) (e.g., the electrical signal trace(s) formed by the conductive layer).

The sensor shift flexure arrangement  1000   a  may illustrate a structure of an insulating layer (e.g., a dielectric layer) and an insulating layer&#39;s application to a base layer. For example, the sensor shift flexure arrangement  1000   a  may include a base layer  1002   a , a first insulating coat  1004   a , and a second insulating coat  1006   a . As shown in  FIG.  10   a   , a first insulating coat  1004   a  may be applied relatively uniformly on and across a relatively flat top surface of the base layer  1002   a . After curing, for example, the second insulating coat  1006   a  may be applied relatively uniformly on and across a portion of a top surface of the cured first insulating coat  1004   a . After the second insulating coat  1006   a  cures, the first insulating coating  1004   a  and the second insulating coat  1006   a  may form an insulating layer such as the dielectric layer  408  illustrated in  FIG.  4   , the dielectric layer  508  illustrated in  FIG.  5   , the dielectric layer  608  illustrated in  FIG.  6   , the dielectric layer  708  illustrated in  FIG.  7   , the dielectric layer  808  illustrated in  FIG.  8   , and/or the dielectric layer  908  illustrated in  FIG.  9   . 
       FIG.  10   b    illustrates a cross-sectional diagram of another shift flexure arrangement  1000   b  for improved signal routing according to some aspects.

The sensor shift flexure arrangement  1000   b  may illustrate another structure of an insulating layer (e.g., a dielectric layer) and an insulating layer&#39;s application to a base layer. For example, the sensor shift flexure arrangement  1000   b  may include a base layer  1002   b , a first insulating coat  1004   b , and a second insulating coat  1006   b . As shown in  FIG.  10   b   , a section of the base layer  1002   b  may be removed forming a removed base layer section  1005   b . The removed base layer section  1005   b  may be removed by etching the base layer  1002   b , for example. Subsequently, the first insulating coat  1004   b  may be applied to a top surface of the base layer  1002   b . The first insulating coat  1004   b  may fill the removed base layer section  1005   b . The first insulating coat  1004   b  may form a relatively flat top surface (e.g., opposite the base layer  1002   b ) so that the first insulating coat  1004   a  has a greater depth or thickness over the area of the removed base layer section  1005   b  compared to the portion of the base layer  1002   a  that does not have a removed section. After curing, for example, the second insulating coat  1006   b  may be applied relatively uniformly on and across a portion of a top surface of the cured first insulating coat  1004   b . After the second insulating coat  1006   b  cures, the first insulating coating  1004   b  and the second insulating coat  1006   b  may form an insulating layer such as the dielectric layer  408  illustrated in  FIG.  4   , the dielectric layer  508  illustrated in  FIG.  5   , the dielectric layer  608  illustrated in  FIG.  6   , the dielectric layer  708  illustrated in  FIG.  7   , the dielectric layer  808  illustrated in  FIG.  8   , and/or the dielectric layer  908  illustrated in  FIG.  9   . The portion of the insulating layer that has a relatively greater depth or thickness may be used to adjust an impedance at a signal pad region or at one or more signal pads to match an impedance at one or more signal traces as described herein. 
       FIG.  10   c    illustrates a cross-sectional diagram of yet another shift flexure arrangement  1000   c  for improved signal routing according to some aspects. The sensor shift flexure arrangement  1000   c  may include one or more same or similar features as camera system  100  of  FIG.  1   , the sensor shift flexure  106  of  FIG.  2   , the camera  300   a  of  FIG.  3 A , the camera  300   b  of  FIG.  3 B , the sensor shift flexure arrangement  400  of  FIG.  4   , the sensor shift flexure arrangement  500  of  FIG.  5   , the sensor shift flexure arrangement  600  of  FIG.  6   , the sensor shift flexure arrangement  700  of  FIG.  7   , the sensor shift flexure arrangement  800  of  FIG.  8   , the sensor shift flexure arrangement  900  of  FIG.  9   , the sensor shift flexure arrangement  1000   a  of  FIG.  10   a   , and/or the sensor shift flexure arrangement  1000   b  of  FIG.  10   b   . The sensor shift flexure arrangement  1000   c  may illustrate yet another structure of an insulating layer (e.g., a dielectric layer) and an insulating layer&#39;s application to a base layer. For example, the sensor shift flexure arrangement  1000   c  may include a base layer  1002   c , a first insulating coat  1004   c , and a second insulating coat  1006   c . As shown in  FIG.  10   c   , the first insulating coat  1004   c  may be applied to a top surface of the base layer  1002   c . The first insulating coat  1004   c  may not be applied uniformly across the top surface of the base layer  1002   c . For example, as shown in  FIG.  10   c   , a portion of the first insulating coat  1004   c  may have a greater height from the base layer  1002   c  compared to another portion of the first insulating coat  1004   c . The first insulating coat  1004   c  may form multiple top surfaces (e.g., opposite the Stojakovic base layer  1002   c ) having varying heights and so that the first insulating coat  1004   c  has a greater depth or thickness over one or more areas with greater heights compared to one or more portions of the first insulating coat  1004   c  having lesser heights. In some aspects, the first insulating coat  1004   c  may be applied in multiple steps. For example, a first application of the first insulating coat  1004   c  may be formed across an entire top surface of the base layer  1002   c  having a uniform depth or thickness. Subsequently, a second application of the first insulating coat  1004   c  may be formed across a portion of the top surface of the first application creating a greater height or thickness of the first insulating coat  1004   c  at the second application site. After curing, for example, the second insulating coat  1006   c  may be applied relatively uniformly on and across a portion of a top surface of the cured first insulating coat  1004   c  having a greater or greatest height. After the second insulating coat  1006   c  cures, the first insulating coating  1004   c  and the second insulating coat  1006   c  may form an insulating layer such as the dielectric layer  408  illustrated in  FIG.  4   , the dielectric layer  508  illustrated in  FIG.  5   , the dielectric layer  608  illustrated in  FIG.  6   , the dielectric layer  708  illustrated in  FIG.  7   , the dielectric layer  808  illustrated in  FIG.  8   , and/or the dielectric layer  908  illustrated in  FIG.  9   . The portion of the insulating layer that has a relatively greater height or thickness may be used to adjust an impedance at a signal pad region or at one or more signal pads to match an impedance at one or more signal traces as described herein. 
       FIG.  11    illustrates an example process  1100  of manufacturing a flexure for improved signal routing according to some aspects. The process  1100  of manufacturing the flexure for improved signal routing is provided from both a side view perspective  1100   a  of the flexure and a top view perspective  1100   b  of the flexure.  FIG.  12    illustrates an example method  1200  of manufacturing a flexure for improved signal routing according to some aspects. The method  1200  of manufacturing the flexure illustrated in  FIG.  12    aligns with the process  1100  of manufacturing the flexure illustrated in  FIG.  11   . The flexure manufactured using the process  1100  and/or the method  1200  may include one or more same or similar features as camera system  100  of  FIG.  1   , the sensor shift flexure  106  of  FIG.  2   , the camera  300   a  of  FIG.  3 A , the camera  300   b  of  FIG.  3 B , the sensor shift flexure arrangement  400  of  FIG.  4   , the sensor shift flexure arrangement  500  of  FIG.  5   , the sensor shift flexure arrangement  600  of  FIG.  6   , the sensor shift flexure arrangement  700  of  FIG.  7   , the sensor shift flexure arrangement  800  of  FIG.  8   , the sensor shift flexure arrangement  900  of  FIG.  9   , the sensor shift flexure arrangement  1000   a  of  FIG.  10   a   , the sensor shift flexure arrangement  1000   b  of  FIG.  10   b   , and/or the sensor shift flexure arrangement  1000   c  of  FIG.  10     c.    
     At step  1201 , a base layer for a flexure may be provided. For example, as shown at block  1101   a  and  1101   b  in  FIG.  11   , a base layer  1102  may be provided for manufacturing a flexure as described herein. In some aspects, the base layer  1102  (e.g., a base alloy) may have a thickness of about 150 μm (10 −6  m) (microns). At step  1203 , a top surface of the base layer may be coated with a first coat of an insulating material. For example, as shown at block  1103   a  and  1103   b  in  FIG.  11   , a first insulating coat  1104  may be applied to a top surface of the base layer  1102 . In some aspects, the first insulating coat  1104  may cover an entire top surface of the base layer  1102 . In some aspects, the first insulating coat  1104  may be a coat of polyimide (PI) (e.g., liquid PI), a hybrid-style PI and adhesive material provided as a laminated cover layer, and/or the like and may have a thickness of about 8 microns. 
     At step  1205 , an inner frame of the flexure may be exposed. For example, as shown at block  1105   a  and  1105   b  in  FIG.  11   , an inner frame  1108  from the first insulating coat  1104  may be exposed. The inner frame  1108 , in some aspects, may be formed using one or more lithography processes. At step  1207 , the inner frame of the flexure may be developed and cured. For example, as shown at block  1107   a  and  1107   b  in  FIG.  11   , the first insulating coat  1104  at the exposed inner frame  1108  may be developed and cured exposing a perimeter of the top surface of the base layer  1102  to the ambient environment. 
     At step  1209 , a second insulating coat is coated on to a top surface of the base layer and a top surface of the first insulating coat. For example, as shown at block  1109   a  and  1109   b  in  FIG.  11   , a second insulating coat  1106  is applied to the perimeter of the top surface of the base layer  1102  and to the top surface of the first insulating coat  1104 . In some aspects, the second insulating coat  1106  may be a coat of polyimide (PI) (e.g., liquid PI), a hybrid-style PI and adhesive material provided as a laminated cover layer, and/or the like and may have a thickness of about 12 microns. At step  1211 , an outer frame of the flexure may be exposed. For example, as shown at block  1111   a  and  1111   b  in  FIG.  11   , an outer frame  1109  from the first insulating coat  1104  and the second insulating coat  1106  may be exposed. The outer frame  1109 , in some aspects, may be formed using one or more lithography processes. At step  1213 , the outer frame of the flexure may be cured. For example, as shown at block  1113   a  and  1113   b  in  FIG.  11   , the outer frame  1109  may be developed and cured exposing a perimeter of the top surface of the base layer  1102  to the ambient environment. In some aspects, flexure arms (e.g., flexure arms  206  in  FIG.  2   ) may also be developed and cured.

For example, as shown in  FIG.  13   , the first area  1324  may be aligned with a portion of the first signal pad region  1314   a . The second area  1326  may be another surface of the signal trace interconnect portion  1322  that is adjacent (e.g., abutting, next to) at least another portion of the dielectric layer  1308 . For example, as shown in  FIG.  13   , the second area  1326  may be aligned with and/or adjacent at least a portion of the cover layer  1316 . Additionally, or alternatively, the second area  1326  may be adjacent one or more electrical traces (e.g., electrical traces  216  illustrated in  FIG.  2   ). 
     In some aspects, the first area  1324  may be beneath (e.g., aligned with) at least a portion of the first signal pad region  1314   a . For example, the first area  1324  may be beneath the first signal pad region  1314   a  and positioned along an axis that is perpendicular to the first area  1324  and intersects with the first signal pad region  1314   a . In some aspects, the first area  1324  may be beneath the entire first signal pad region  1314   a .

     As shown in  FIG.  14   , the signal trace interconnect portion  1422  may include at least a first area  1424  and a second area  1426 . The first area  1424  may be a surface of the signal trace interconnect portion  1422  that is adjacent (e.g., abutting, next to) at least a portion of the dielectric layer  1408 . For example, as shown in  FIG.  14   , the first area  1424  may be adjacent or aligned with at least a portion of the first signal pad region  1414   a . The second area  1426  may be another surface of the signal trace interconnect portion  1422  that is adjacent (e.g., abutting, next to) at least another portion of the dielectric layer  1408 .

For example, the second area  1426  may be beneath the cover layer  1416  and positioned along an axis that is perpendicular to the second area  1426  and intersects with the cover layer  1416 . In some aspects, the cover layer  1416  may be beneath one or more electrical traces (e.g., electrical traces  216  illustrated in  FIG.  2   ) routed on an inner frame (e.g., the inner frame  202  illustrated in  FIG.  2   ), one or more flexure arms (e.g., flexure arm(s)  206  illustrated in  FIG.  2   ), and/or an outer frame (e.g., the outer frame  204  illustrated in  FIG.  2   ) and/or not beneath a remainder of the cover layer  1416 . For example, the second area  1426  may be beneath one or more signal traces aligned with the cover layer  1416 . 
     As shown in  FIG.  14   , the sensor shift flexure arrangement  1400  may include an impedance adjusting feature  1428 . As indicated in  FIG.  13   , the signal trace interconnect portion  1322  of the sensor shift flexure arrangement  1300  may have a relatively large amount of coupling  1324 , via the intermediate portion  1320 , to electrical grounding portion/reference plane  1318 . By comparison, as indicated in  FIG.  14   , the signal trace interconnect portion  1422  of the sensor shift flexure arrangement  1400  may have a relatively smaller amount of coupling  1426 , via the intermediate portion  1420 , to electrical grounding portion/reference plane  1418 . The smaller amount of coupling  1426  in the sensor shift flexure arrangement  1400  may be achieved by including one or more impedance adjusting features (e.g., impedance adjusting feature  1428 ) in the electrical grounding portion/reference plane  1418 . The impedance adjusting feature  1428 , for example, may be designed to reduce the amount of coupling and thereby increase the impedance of the first signal pad region  1414   a  to better match the target channel impedance, thereby enabling time domain reflectometry (TDR) improvements. The impedance adjusting features  1428  in combination with the greater distance between the first signal pad region  1414   a  and the base layer  1402  may also be designed to reduce the amount of coupling and thereby increase the impedance of the first signal pad region  1414   a  to better match the target channel impedance, thereby enabling time domain reflectometry (TDR) improvements. For example, better matching pad impedance to the channel impedance may help reduce channel return loss. Reducing channel return loss may improve signal integrity. Improving signal integrity may enable a higher bandwidth for the channel. Furthermore, improving signal integrity may help reduce system power consumption, e.g., by reducing signal/power transmitter swing and/or optimizing signal/power receiver equalization needs. 
     In various embodiments, the impedance adjusting feature  1428  may comprise (i) a void (e.g., an empty space) and/or (ii) a cavity that is at least partially filled with an insulating material (e.g., epoxy). In various embodiments, the impedance adjusting feature  1428  may be positioned along an axis that intersects with the signal trace interconnect portion  1422  whose impedance is being adjusted using the impedance adjusting feature  1428 . For example, the impedance adjusting feature  1428  may be located within a space underneath a given electrical signal pad  1414 . While  FIG.  14    indicates the presence of a single impedance adjusting feature  1428 , it should be appreciated that multiple discrete impedance adjusting features  1428  may be included below the first signal pad region  1414   a.    
     In some embodiments, the impedance adjusting feature(s)  1428  may be offset from a center of the first signal pad region  1414   a , e.g., as indicated in  FIG.  14   . In some embodiments, the impedance adjusting feature(s)  1428  may be centered with the first signal pad region  1414   a . Characteristics of the impedance adjusting feature(s)  1428 , such as, but not limited to, size (e.g., depth and/or width), position, location, shape, material, amount of fill, etc., may be determined based at least in part on a predetermined target impedance (for the signal pad region(s)  1414 ) that the impedance adjusting feature(s)  628  are designed to achieve, e.g., to match the signal channel impedance requirements, and/or to adjust the impedance of the electrical signal pad(s) to within a threshold impedance value proximity to the signal channel impedance. 
     In some embodiments, the impedance adjusting feature(s)  1428  may comprise a slot formed using one or more subtractive manufacturing processes (e.g., etching and/or lithography, etc.). The slot may have a depth, in the direction orthogonal to the image plane, that extends through at least a portion of the electrical grounding portion/reference plane  1418 . That is, at least a portion of the electrical grounding portion/reference plane  1418  may define the impedance adjusting feature(s)  1428 . In some embodiments, the depth of the slot may extend through a portion of the first conductive layer  1404  or through the whole depth of the first conductive layer  1404  without extending into the base layer  1402 . In some embodiments, the depth of the slot may extend through the first conductive layer  1404  and a portion of the base layer  1402 . In some embodiments, the depth of the slot may extend through the first conductive layer  1404  and through the whole depth of the base layer  1404 . In some embodiments, e.g., where the first conductive layer  1404  is not present, the depth of the slot may extend through a portion of the base layer  1418  or through the whole depth of the base layer  1418 . 
     According to some embodiments, the slot may have a width, in a direction parallel to the image plane, that extends a portion of the width of the first signal pad region  1414   a  or that extends the whole width of the first signal pad region  1414   a . In various embodiments, the slot may have an outermost periphery, in the direction parallel to the image plane, that is smaller than or equal to the outermost periphery of the first signal pad region  1414   a . Furthermore, the outermost periphery of the slot may be constrained to a position within the outermost periphery of the first signal pad region  1414   a , e.g., if both outermost peripheries were projected onto the image plane. 
     Characteristics of the impedance adjusting feature  1428 , such as, but not limited to, size (e.g., depth and/or width), position, location, shape, material, amount of fill, etc., may be determined based at least in part on a predetermined target impedance (for the electrical signal pad(s)  1414 ) that the impedance adjusting feature  1428  is designed to achieve, e.g., to match the signal channel impedance requirements, and/or to adjust the impedance of the electrical signal pad(s) to within a threshold impedance value proximity to the signal channel impedance. It should be understood that while the impedance adjusting feature  1428  may be positioned beneath the first signal pad region  1414   a , additionally, or alternatively, one or more additional impedance adjusting features may be positioned beneath the first signal pad region  1414   a  and/or the second signal pad region  1414   b  and may include one or more same or similar features as described herein with respect to the impedance adjusting feature  1428 . Each of the alternative or additional impedance adjusting features may be individually custom to adjust an impedance at the respective signal pad region to match an impedance at one or more associated signal traces. 
       FIG.  15    illustrates a schematic cross-sectional side view of a portion of an example camera  1500  that may include one or more actuators and a sensor shift flexure arrangement for improved signal routing, in accordance with some embodiments. In some embodiments, camera  1500  may include a lens group  1502 , an image sensor  1504 , and a voice coil motor (VCM) actuator module  1506 . The lens group  1502  may define an optical axis. The image sensor  1504  may be configured to capture light passing through the lens group  1502  and convert the captured light into image signals. In some cases, the VCM actuator module  1506  may be one of multiple VCM actuator modules of the camera  1500 . For instance, the camera  1500  may include four such VCM actuator modules  1506 , such as two pairs of VCM actuator modules  1506  that oppose one another relative to the lens group  1502 . The VCM actuator modules  1506  may be configured to move the lens group  1502  along the optical axis (e.g., in the Z-axis direction, to provide autofocus (AF) functionality) and/or tilt the lens group  1502  relative to the optical axis. Furthermore, the VCM actuator module(s)  1506  may be configured to move the image sensor  1504  in directions orthogonal to the optical axis (e.g., in the X-axis and/or Y-axis directions, to provide optical image stabilization (OIS) functionality). 
     In various embodiments, the VCM actuator module  1506  may include a magnet  1508  (e.g., a stationary single pole magnet), a lens holder  1510 , a substrate  1512 , a top flexure (not shown), and a bottom flexure  1514  (e.g., comprising one or more sensor shift flexure arrangements disclosed herein). In various embodiments, the bottom flexure  1514  may be the same as, or similar to, flexure  106  in  FIGS.  1 - 2   , flexure  302  in  FIG.  3 A , and/or flexure-circuit hybrid structure  308  in  FIG.  3 B . Furthermore, the VCM actuator module  1506  may include an AF coil  1516  and a bottom sensor positioning (SP) coil  1518 . 
     In some embodiments, the lens holder  1510  may hold, or otherwise support, the AF coil  1516  proximate a side of the magnet  1508 . The lens holder  1510  may be coupled to the lens group  1502  such that the lens group  1502  shifts together with the lens holder  1510 . 
     In various embodiments, the substrate  1512  may hold, or otherwise support, the bottom SP coil  1518  proximate a bottom side of the magnet  1508 . The substrate  1512  may be coupled to the image sensor  1504  such that the image sensor  1504  shifts together with the substrate  1512 . In some embodiments, the substrate  1512  may also be coupled with, or may otherwise support, an infrared cut-off filter (IRCF)  1520  (and/or one or more other optical elements), e.g., as indicated in  FIG.  15   . 
     In some embodiments, the VCM actuator module  1506  may include a position sensor  1522  (e.g., a Hall sensor) for position detection based on movement of the SP coil  1518  in directions orthogonal to the optical axis. For example, the position sensor  1522  may be located on the substrate  1512  proximate to the SP coil  1518 . 
     The flexure  1514  may be configured to provide compliance for motion of the substrate  1512  in directions orthogonal to the optical axis. Furthermore, the flexure  1514  may be configured to suspend the substrate  1512  and the image sensor  1504  from one or more stationary structures  1524  of the camera  1500 . 
     The top flexure (not shown) may be configured to mechanically and electrically connect the lens holder  1510  to the shield can  1526  and/or to one or more other stationary structures (e.g., stationary structure  1524 ). The top flexure may be configured to provide compliance for movement of the lens holder  1510  along the optical axis and for tilt of the lens holder  1510  relative to the optical axis. The shield can  1526  may encase, at least in part, an interior of the camera  1500 . The shield can  1526  may be a stationary component that is static relative to one or more moving components (e.g., the lens holder  1510  and substrate  1512 ). 
     In some embodiments, the stationary magnet  1508  may be fixed to a stationary structure (e.g., magnet holder  1528 ). In some examples, each of the AF coil  1516  and the SP coil  1518  may be a race track coil. 
     Electromagnetic interaction between the AF coil  1516  and the magnet  1508  may produce Lorentz forces that cause the lens holder  1510  to move along the optical axis and/or to tilt relative to the optical axis. Electromagnetic interaction between the SP coil  1518  and the magnet  1508  may produce Lorentz forces that cause the substrate  1512  to move in directions orthogonal to the optical axis. The lens group  1502  may shift together with (e.g., in lockstep with) the lens holder  1510 . Furthermore, the image sensor  1504  may shift together with (e.g., in lockstep with) the substrate  1512 . 
     As discussed herein, electrical contacts/connections may allow for electrical signals (e.g., image signals) to be conveyed from the image sensor  1504  to a controller (not shown). For instance, the image sensor  1504  may be in electrical contact with the substrate  1512  via one or more contacts, and thus image signals may be conveyed from the image sensor  1504  to the substrate  1512 . The image signals may be conveyed from the substrate  1512  to one or more external components (e.g., external component(s)  314  in  FIGS.  3 A- 3 B ) via the flexure  1514  and a flex circuit (e.g., flex circuit  108  in  FIG.  1   , flex circuit  304  in  FIG.  3 A , etc.). According to various examples, electrical contacts/connections may allow for current to be conveyed from the controller to the substrate  1512  to drive the SP coil  1518 . 
       FIG.  16    illustrates a schematic representation of an example device  1600  that may include one or more cameras.

     In some embodiments, the device  1600  may include a display system  1602  (e.g., comprising a display and/or a touch-sensitive surface) and/or one or more cameras  1604 . In some non-limiting embodiments, the display system  1602  and/or one or more front-facing cameras  1604   a  may be provided at a front side of the device  1600 , e.g., as indicated in  FIG.  16   . Additionally, or alternatively, one or more rear-facing cameras  1604   b  may be provided at a rear side of the device  1600 . In some embodiments comprising multiple cameras  1604 , some or all of the cameras  1604  may be the same as, or similar to, each other. Additionally, or alternatively, some or all of the cameras  1604  may be different from each other. In various embodiments, the location(s) and/or arrangement(s) of the camera(s)  1604  may be different than those indicated in  FIG.  16   . 
     Among other things, the device  1600  may include memory  1606  (e.g., comprising an operating system  1608  and/or application(s)/program instructions  1610 ), one or more processors and/or controllers  1612  (e.g., comprising CPU(s), memory controller(s), display controller(s), and/or camera controller(s), etc.), and/or one or more sensors  1614  (e.g., orientation sensor(s), proximity sensor(s), and/or position sensor(s), etc.). In some embodiments, the device  1600  may communicate with one or more other devices and/or services, such as computing device(s)  1616 , cloud service(s)  1618 , etc., via one or more networks  1620 . For example, the device  1600  may include a network interface (e.g., network interface  910  in  FIG.  9   ) that enables the device  1600  to transmit data to, and receive data from, the network(s)  1620 . Additionally, or alternatively, the device  1600  may be capable of communicating with other devices via wireless communication using any of a variety of communications standards, protocols, and/or technologies. 
       FIG.  17    illustrates a schematic block diagram of an example computer system  1700  that may include a camera having a sensor shift flexure arrangement for improved signal routing, e.g., as described herein with reference to  FIGS.  1 - 14   . In addition, computer system  1700  may implement methods for controlling operations of the camera and/or for performing image processing on images captured with the camera. In some embodiments, the device  1600  (described herein with reference to  FIG.  16   ) may additionally, or alternatively, include some or all of the functional components of the described herein. 
     The computer system  1700  may be configured to execute any or all of the embodiments described above. In different embodiments, computer system  1700  may be any of various types of devices, including, but not limited to, a personal computer system, desktop computer, laptop, notebook, tablet, slate, pad, or netbook computer, mainframe computer system, handheld computer, workstation, network computer, a camera, a set top box, a mobile device, an augmented reality (AR) and/or virtual reality (VR) headset, a consumer device, video game console, handheld video game device, application server, storage device, a television, a video recording device, a peripheral device such as a switch, modem, router, or in general any type of computing or electronic device. 
     In the illustrated embodiment, computer system  1700  includes one or more processors  1702  coupled to a system memory  1704  via an input/output (I/O) interface  1706 . Computer system  1700  further includes one or more cameras  1708  coupled to the I/O interface  1706 . Computer system  1700  further includes a network interface  1710  coupled to I/O interface  1706 , and one or more input/output devices  1712 , such as cursor control device  1714 , keyboard  1716 , and display(s)  1718 . In some cases, it is contemplated that embodiments may be implemented using a single instance of computer system  1700 , while in other embodiments multiple such systems, or multiple nodes making up computer system  1700 , may be configured to host different portions or instances of embodiments. For example, in one embodiment some elements may be implemented via one or more nodes of computer system  1700  that are distinct from those nodes implementing other elements. 
     In various embodiments, computer system  1700  may be a uniprocessor system including one processor  1702 , or a multiprocessor system including several processors  1702  (e.g., two, four, eight, or another suitable number).

For example, in various embodiments processors  1702  may be general-purpose or embedded processors implementing any of a variety of instruction set architectures (ISAs), such as the x86, PowerPC, SPARC, or MIPS ISAs, or any other suitable ISA. In multiprocessor systems, each of processors  1702  may commonly, but not necessarily, implement the same ISA. 
     System memory  1704  may be configured to store program instructions  1720  accessible by processor  1702 . In various embodiments, system memory  1704  may be implemented using any suitable memory technology, such as static random access memory (SRAM), synchronous dynamic RAM (SDRAM), nonvolatile/Flash-type memory, or any other type of memory. Additionally, existing camera control data  1722  of memory  1704  may include any of the information or data structures described above. In some embodiments, program instructions  1720  and/or data  1722  may be received, sent or stored upon different types of computer-accessible media or on similar media separate from system memory  1704  or computer system  1700 . In various embodiments, some or all of the functionality described herein may be implemented via such a computer system  1700 . 
     In one embodiment, I/O interface  1706  may be configured to coordinate I/O traffic between processor  1702 , system memory  1704 , and any peripheral devices in the device, including network interface  1710  or other peripheral interfaces, such as input/output devices  1712 .

Also, in some embodiments some or all of the functionality of I/O interface  1706 , such as an interface to system memory  1704 , may be incorporated directly into processors  1702 . 
     Network interface  1710  may be configured to allow data to be exchanged between computer system  1700  and other devices attached to a network  1724  (e.g., carrier or agent devices) or between nodes of computer system  1700 .
