Title: Sealable multi-surface electronics thermal conduction package

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The present application is a continuation of and claims the benefits of and priority to U.S. patent application Ser. No. 15/937,521, filed Mar. 27, 2018, of the same title, the entire disclosure of which is hereby incorporated herein by reference, in its entirety, for all that it teaches and for all purposes. 
    
    
     FIELD 
     The present disclosure is generally directed to electronics packaging, in particular, toward environmentally-sealed thermally-controlled packages for electronic component assemblies. 
     BACKGROUND 
     Most electronic devices generate heat while in use. This heat is typically generated by the flow of electric current through one or more resistive elements and/or components in the electronic device. When the heat generated by these elements and/or components is not efficiently removed, the temperatures of an electronic device can exceed a normal operating range. Operating electronics at temperatures outside of the normal operating range, even periodically, can cause premature failures and result in shorter component life spans. 
     The efficient thermal management of electronic components and devices generally requires one or more active and/or passive cooling elements. For example, typical microprocessors may generate heat that can be removed or dissipated via an attached heat sink and/or some other cooling element/system, such as a fan, directed cooled air, fluid cooling, etc. In this example, the heat generated may be routed to, and/or dissipated, into an environment immediately surrounding the microprocessors. 
     However, the options for removing heat from an electronic device within a sealed environment (e.g., hermetic package, pseudo-hermetic package, sealed enclosure, etc.) may be limited to those approaches employing costly, sizable, and/or complex cooling systems.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure will be described in connection with electronics packaging, and in some embodiments, the construction, structure, and arrangement of elements making up a sealable multi-surface electronics thermal conduction package. 
     In some embodiments, the present disclosure describes a compact thermal conduction package configured to conductively cool multiple surfaces of electronics sealed inside a package. The package may include a housing and an interior space, or envelope, configured to receive a printed circuit board assembly (“PCBA”) with one or more microprocessors and/or other heat generating elements. In one embodiment, the PCBA may include microprocessors disposed on opposing planar faces of the printed circuit board (PCB) or substrate. In general, the present disclosure provides a package that can be elastically deformed to open a dimension of the envelope, or receiving cavity, such that a complete PCBA can be inserted inside the interior space of the package. Once inserted, the package may be returned to its undeformed, or substantially undeformed, state such that surfaces in the interior space of the package contact one or more of the heat generating elements on the PCBA creating a conductive thermal path from the heat generating elements to the housing of the package. 
     In some embodiments, the package may include an extruded shape or housing. The housing may include a number of cooling fins, or heat sink surfaces, disposed on an outside of the housing, at least one pressure contact area, and an interior space/receiving cavity and/or PCB envelope configured to receive a PCBA and/or other electronics. 
     As described herein, the housing of the package may include a weakened, controlled cross-sectional area, or flexure, configured to elastically bend, or deform, when a force is applied to one or more of the ends having the pressure contact area. For example, as force, F is applied to the ends of the package, an internal height dimension, HC, may be increased from a first height dimension, HC, to a second increased height dimension, (HC+Y), where Y is a non-zero distance, creating an expanded space to receive a PCBA and/or other electronics. 
     Although described herein as compressive, or squeezing, forces, it should be appreciated, that only one force, F, need be applied to an end of the package while the opposing end is held in place. This containment of the package while a force, F, is applied effectively provides an equal and opposing force against the opposing end of the package. Further, the flexure area(s) of the package may be designed to control the application of force such that the envelope is opened outwardly from the center and not collapsed toward the interior space of the package. 
     Once compressed, and while maintaining the package in the opened state, a PCBA or other electronic device/system may be inserted into the elastically deformed opening of the package. After the PCBA is in place, the force, F, may be removed from the package and the package will attempt to return from the elastically deformed state having expanded internal height dimension (HC+Y) to the original undeformed state having internal height dimension HC. In some embodiments, the package may be dimensioned and toleranced such that the height of the PCBA components is equal to or slightly greater than the internal height dimension HC in the original undeformed state. This dimensioning may provide a vertical clamping force on the components of the PCBA when the compressive, or opening, force is removed. Among other things, this clamping force may hold the PCBA inside the package and in direct conductive thermal communication with the housing. The heat generating elements of the PCBA may be in contact with the housing at one or more conduction cooling contact areas. 
     Heat generated from the PCBA inside the package may be passed through the housing to the cooling fins disposed on the outside of the housing walls. In some embodiments, a thermal interface material may be disposed between the heat generating elements on the PCBA and the conduction cooling contact areas prior to clamping the PCBA in place inside the package. 
     In some embodiments, the package may be sealed via one or more soldered, brazed, welded, and/or otherwise affixed endplates. The endplates may include one or more connectors to the PCBA and/or provide an electrical interconnection to the PCBA from the outside of the package. In some cases, these electrical connectors and/or electrical interconnections may be hermetically sealed, potted, and/or pseudo-hermetically sealed within the endplates. 
     As can be appreciated, the compact package described herein can provide efficient cooling of multi-surface electronics equipment in a hermetic and/or sealed environment. Further, due in part to the small size and passive cooling structure, the device is capable of being installed in any environment or area of a vehicle, machine, system, etc. 
     In some embodiments, the package may employ a multiple-flexure system in the extruded housing such that an elastic opening force may provide a linear translation (e.g., in the vertical direction) of one or more cooling contact surfaces of the housing. As the opening force is applied to the pressure contact area, the force displaces the angled flexures outwardly from the center of the package. This displacement results in a linear translation of each of the cooling contact surfaces creating a more even clamping pressure on the PCBA elements when the opening force is removed. It is an aspect of the present disclosure that the flexures may be sized and/or tuned to provide a desired clamping force against the one or more components of the PCBA. 
     Referring to  FIGS. 1A-1C , various views of a printed circuit board assembly (PCBA)  100  are shown in accordance with embodiments of the present disclosure. In some embodiments, the features of the PCBA  100  may be described with reference to one or more axes (e.g., X-axis, Y-axis, Z-axis), or planes (e.g., XZ-plane, XY-plane, YZ-plane) of the coordinate system  102  shown. As shown, the PCBA  100  may include a substantially planar substrate  104  having a length, LS, running from a first end  122  to a second end  126  of the substrate  104 . This length, LS, and a width, WS, of the substrate  104  may define at least one substantially planar component mounting surface  106 A,  106 B disposed on the first side and/or second side of the substrate  104 . The first surface  106 A of the substrate  104  may be separated from the second surface  106 B of the substrate  104  by a thickness, or height, HS, corresponding to one or more layers of material making up the substrate  104 . In some embodiments, the length, LS, and width, WS, of the substrate  104  may correspond to the overall length and width of the PCBA  100 . The height, HS, of the substrate  104 , however, may differ from the height, HP, of the PCBA  100 . For example, the height, HP, of the PCBA may include an overall height of the components attached, soldered, fused, and/or protruding from one or more surfaces  106 A,  106 B of the PCBA  100  in addition to the height, HS, of the substrate  100 . 
     In some embodiments, the substrate  104  may correspond to a printed circuit board (PCB). In one embodiment, the substrate  104  may include one or more layers of dielectric material and at least one layer disposed thereon including electrically conductive traces  120  configured to electrically interconnect electronic components of the PCBA  100 . The traces  120  may run from one or more legs, contacts, or pins associated with passive electronic components (e.g., resistors, capacitors, diodes, transformers, etc.) and/or active electronic components (e.g., transistors, processors, application specific integrated circuit (ASIC), microprocessors, and/or other components configured to actively control electron flow, etc.) to one or more other components, connectors, and/or ground features associated with the PCBA  100 . In some embodiments, the traces  120  may pass from a first surface  106 A or side of the PCBA  100  to a second surface  106 B or side of the PCBA  100 . 
     The substrate  104  may be made from rigid material configured to mechanically support the electronic components. Examples of the rigid materials may include, but are in no way limited to, fiberglass, linen, ceramic, glass, resin, epoxy, phenolic cotton paper, woven fiberglass cloth, glass and polyester, paper and epoxy, insulated metal, polymer, polyimide, polytetrafluoroethylene, etc., and/or combinations thereof. The electrically conductive traces  120  of the substrate  104  may be machined, stamped, cut, etched, deposited, and/or otherwise formed from a conductive material. Examples of conductive materials may include, but are in no way limited to, copper, silver, gold, aluminum, graphene, etc., and/or other metals. For clarity of description, a limited number of traces  120  are shown in  FIGS. 1A-1C . 
     As shown in  FIGS. 1A-1C , the PCBA  100  may include a number of heat generating elements  108 A-D, including at least one surface  110 A-D from which heat may be transferred and/or emitted. The heat generating elements  108 A-D may correspond to passive or active electronic components. In one embodiment, the heat generating elements  108 A-D may be microprocessors, processors, and/or integrated circuits. The heat generating elements  108 A-B may be attached to a first surface  106 A of the substrate  104  via surface mount and/or through-hole mount soldering and/or via at least one adhesive layer disposed between the heat generating elements  108 A-B and the first surface  106 A. Heat generating elements  108 C-D may be attached to a second surface  106 B of the substrate  104  via surface mount and/or through-hole mount soldering and/or via at least one adhesive layer disposed between the heat generating elements  108 C-D and the second surface  106 B. In some embodiments, the first surface  106 A may be disposed opposite the second surface  106 B, or vice versa, separated by a material or substrate thickness, HS. 
     In addition to one or more heat generating elements  108 A-D, the PCBA  100  may include other electronic components  112 A,  112 B, connectors  116 A,  116 B, electrical contacts, and/or mechanical features. The connectors  116 A,  116 B may correspond to communications connectors, power connectors, and/or a combination of communications and power connectors. In some embodiments, the connectors  116 A,  116 B may be disposed at the same end  126  of the substrate  104  or PCBA  100 . Among other things, locating the connectors  116 A,  116 B at the same end  126  of the PCBA  100  allows a single end of the package to house the mating connections and/or passthrough electrical interconnections from an interior of the sealed package to an exterior of the sealed package. 
     In some embodiments, the PCBA  100  may include a plurality of heat generating elements  108 A-D disposed on one or more sides or surfaces  106 A,  106 B of the substrate  104 .  FIG. 1C  shows first and second heat generating elements  108 A,  108 B disposed on the first surface  106 A of the substrate, while third and fourth heat generating elements  108 C,  108 D are shown disposed on the second surface  106 B of the substrate  104 . As provided above, the overall height, HP, of the PCBA  100  may be measured between points of the PCBA  100  that are disposed furthest from the substrate  104  (e.g., extending outwardly along the Y-axis). For example, the heat generating elements  108 A-D are the tallest electronic components attached to the first and second surfaces  106 A,  106 B, respectively, on either side of the substrate  104 . In this example, the overall height, HP, of the PCBA  100  may be measured from the heat emitting surface  110 B of the second heat generating element  108 B to the heat emitting surface  110 C of the third heat generating element  108 C. The heat emitting surfaces  110 A-D of the heat generating elements  108 A-D may be substantially planar and/or substantially parallel to the first and/or second surfaces  106 A,  106 B of the substrate  104 . 
       FIG. 2A  shows a perspective view of a sealable multi-surface electronics thermal conduction package  200  in accordance with embodiments of the present disclosure. The package  200  may comprise a body including a profile, or extrusion, surface  204  and shape having a first end  208 A, a second end  208 B, a first contact surface  212 A (not shown in  FIG. 2A ), a second contact surface  212 B, and a hollow space, or electronics receiving cavity,  220  disposed therebetween. The package  200  may include a number of heat sink elements  216  configured to transfer thermal energy from a surface of the body to an environment surrounding the body. The heat sink elements  216  may be configured as straight fins, protrusions, pins, flared fins, etc., and/or combinations thereof. In some embodiments, the heat sink elements  216  may extend along a length of the package  200 , for example, from the front  222  (e.g., at the profile surface  204 ) to the rear  226  of the package  200 . 
     In some embodiments, the package  200  may include one or more controlled bend regions, areas, or flexures,  224 . As shown in  FIG. 2A , the package  200  includes flexures  224  disposed at an approximate center of the package  200 , in both the upper and lower portions  206 A,  206 B of the profile surface  204 . The flexures  224  may be shaped such that a force applied to the first and/or second contact surfaces  212 A,  212 B of the package  200  displaces the upper and lower portions  206 A,  206 B of the package  200  in a direction (e.g., the Y-axis direction) away from the center of the package  200 . 
     The package  200  may be made from plastic, metal, carbon fiber, linen, composites, epoxy resin, etc., and/or combinations thereof. In one embodiment, the material of the package  200  may be thermally conductive. Thermally conductive material may provide a thermal path from an interior space  220  of the package  200  to an environment outside the package. This thermal path may serve as the path by which heat can be transferred from electronics contained inside the package  200 . Examples of thermally conductive materials may include, but are in no way limited to, steel, titanium, aluminum, copper, tin, nickel, iron, etc., alloys thereof, and/or combinations thereof. The package  200  may be machined, formed, molded, cast, extruded, etc., and/or combinations thereof. In one embodiment, the material of the package  200  may be extrudable and thermally conductive. One example of an extrudable and thermally conductive material is aluminum. In any event, the package  200  may be designed such that the profile surface  204  defines a shape corresponding to at least one shape of an extrusion die used to create the package  200 . In this example, the package  200  may be formed by heating and softening a billet of extrudable material (e.g., aluminum, etc.), forcing the billet of extrudable material through one or more extrusion dies (e.g., including the features, or inverse features, of the profile shape  204 , etc.), cooling the extruded material as it exits the one or more extrusion dies, and then cutting the extruded material to length. Once extruded and cut to length, the body can be deburred, cleaned, machined, and/or finished (e.g., coated, anodized, nickel plated, etc.). The extruded body provides a cost-effective and integral, one-piece, housing for the sealable multi-surface electronics thermal conduction package  200 . 
       FIGS. 2B and 2C  shows front elevation views of the sealable multi-surface electronics thermal conduction package  200  of  FIG. 2A  in various assembly states in accordance with embodiments of the present disclosure. In particular,  FIG. 2B  shows the package  200  in a normal, uncompressed, or first state and  FIG. 2C  shows the package  200  in a compressed, or second state, where the force of compression causes the opening, or receiving cavity,  220  to open in the Y-axis direction. In some embodiments, the package  200  may be centerline symmetrical, for example, along a centerline running through the center of the package  200  along the X-axis and/or along a centerline running through the center of the package  200  along the Y-axis. 
     As shown in  FIG. 2B , the package  200  in the first or normal state provides a receiving cavity  220 , configured as a hollow space in the center of the package  200 , having a cavity height, HC. The cavity height, HC, may be defined as a distance between a first interior surface of the package  200  and a second opposing interior surface of the package  200  along the Y-axis. This cavity height, HC, may remain substantially the same along the X-axis direction from a position adjacent to the first end  208 A of the package  200  to a position adjacent to the second end  208 B of the package  200 . Additionally or alternatively, the cavity height, HC, may remain substantially the same along the length of the package (e.g., along the Z-axis direction). In some embodiments, the cavity height, HC, may be sized to substantially match an overall height, HP, of the PCBA  100  (see, e.g.,  FIG. 1C ). In one embodiment, the cavity height, HC, may be undersized, or sized less than the overall height, HP, of the PCBA  100 , by an amount to provide a clamping, or holding, force on any electronics (e.g., the PCBA  100 , etc.) disposed inside the receiving cavity  220 . In another embodiment, the cavity height, HC, may be oversized, or sized greater than the overall height, HP, of the PCBA  100 , by an amount to allow a thermal interface material to be inserted between any inserted electronics (e.g., the PCBA  100 , etc.) and the interior surfaces of the receiving cavity  220 . 
     In  FIG. 2C , the package  200  has been compressed (e.g., in the X-axis direction) by an applied force  230  such that the first end  208 A and the second end  208 B of the package  200  are displaced closer together toward the center of the package  200 . In this second state, the width of the package  200  (e.g., the dimension from the first contact surface  212 A to the second contact surface  212 B) is less than the width of the package  200  in the first state. As the applied force  230  moves the first and second ends  208 A,  208 B closer together, the force  230  simultaneously moves the upper portion  206 A and the lower portion  206 B apart from one another (e.g., in a direction away from the center of the package  200  along the Y-axis). The displacement of the upper and lower portions  206 A,  206 B increases the cavity height, HC, by an opening distance, Y. As shown in  FIG. 2C , the flexures  224  control the movement direction and displacement of the upper and lower portions  206 A,  206 B when the force  230  is applied and/or removed. In some embodiments, the increased cavity height, (HC+Y), may provide enough clearance inside the receiving cavity  220  to allow a PCBA  100 , or other electronics, to be inserted therein. In some embodiments, the structure of the package  200  may prevent a PCBA  100  from being inserted into the receiving cavity  220  in the first state (e.g., because the cavity height, HC, may be substantially similar to, or less than, the overall height, HP, of the PCBA  100 , etc.) and only allow insertion of the PCBA  100  when the package  200  is flexed, in the second state. Although shown as displacing angularly from the first and second ends  208 A,  208 B, (e.g., relative to the XZ-plane, etc.) it should be appreciated that the flexures  224  and/or structure of the profile shape  204  of the package  200  may be configured (e.g., adding more flexures, shaping each flexure, including a controlled pivot area, etc., and/or combinations thereof) to provide a linear, or substantially orthogonal, translation of the interior surfaces relative to the XZ-plane. 
     It is an aspect of the present disclosure that the package  200  may be elastically flexed from the first state (e.g., shown in  FIG. 2B ) to the second state (e.g., shown in  FIG. 2C ), and vice versa. For instance, the material of the package  200  and design of the flexures  224  may allow the package  200  to be repeatedly flexed within the elastic range of the package material. Additionally or alternatively, the package  200  may elastically return from the second state to the first state when the applied force  230  is removed from the package  200 . This return from the second state to the first state may occur without the application of any external force (e.g., force applied to the package  200 , etc.). For example, the elastic energy (e.g., potential mechanical energy) stored in the package  200  in the second state may be converted into kinetic energy substantially moving the package  200  back to the first state when the applied force  230  is removed from the package  200 . 
       FIGS. 3A and 3B  show front elevation views of the package  200  during assembly stages inserting electronics, such as a PCBA  100 , into the receiving cavity  220 . In  FIG. 3A , the package  200  is shown in the second, or flexed, state. While in the flexed state, the applied force  230  holds, or maintains, the package  200  in an “open” configuration where the receiving cavity has an increased cavity height, (HC+Y). In the second state, the increased cavity height, (HC+Y) provides clearance  304  around the heat generating elements  108 A-D and/or other electronic components. The clearance  304  allows the PCBA  100  to be inserted into the receiving cavity  220  of the package  200 . In some embodiments, and while in the second state, the clearance  304  may allow the PCBA  100  to be inserted into the receiving cavity  220  of the package  200  without any interference or restriction between the PCBA  100  and the package  200 . 
     In  FIG. 3B , the package  200  is shown in the first, or substantially unflexed, state. As described above, the package  200  may be unflexed (e.g., having no applied force  230  flexing the package  200 , etc.) but may provide a clamping force against the heat generating elements  108 A-D holding the PCBA  100  in place inside the receiving cavity  220  of the package  200 . As shown in  FIG. 3B , at least one interior surface of the upper portion  206 A of the package  200  is contacting the upper heat generating elements  108 A-B at thermal contact areas  308 , while at least one interior surface of the lower portion  206 B of the package  200  is contacting the lower heat generating elements  108 CA-D at opposing thermal contact areas  308 . The interior surfaces of the receiving cavity  220  may be in contact, or coplanar, with the heat emitting surfaces  110 A-D of the heat generating elements  108 A-D. In some embodiments, a thermal interface material (TIM) may be disposed between the at least one interior surface of the receiving cavity  220  and the heat generating elements  108 A-D. The TIM may be a thermally conductive grease, tape, adhesive, or other thin material configured to provide an effective thermal path (e.g., a thermal coupling, etc.) between the heat generating elements  108 CA-D of the PCBA  100  and the material of the package  200 . 
     Referring now to  FIGS. 4A-4F , perspective views of different steps in an assembly process for the sealable multi-surface electronics thermal conduction package with integrated electronics  400  are shown in accordance with embodiments of the present disclosure. In some embodiments, the method of manufacturing described in conjunction with  FIG. 6  may correspond to one or more of the steps illustrated in conjunction with  FIGS. 4A-4F . 
     As shown in  FIG. 4A , a package  200  is provided in a first, unflexed, state prepared for electronics integration. The package  200  may correspond to any of the packages  200 ,  500  described herein. The PCBA  100  may be aligned with the receiving cavity  220  of the package  200  in  FIG. 4A . In some embodiments, the front  122  of the PCBA  100  or the rear  126  of the PCBA  100  may be inserted into the receiving cavity  220  first. The receiving cavity  220  may be open on one or more of a front  222  and/or rear  222  of the package  200 . In some cases, the PCBA  100  may be inserted in either open end (e.g., the front  222  and/or rear  222 ) of the receiving cavity  220 . 
     In  FIG. 4B , the package  200  may be opened into the second, flexed, state by applying a compressive force  230  to the first and/or second contact surfaces  212 A,  212 B of the package  200 . As provided above, this compressive force  230  may increase an internal dimension (e.g., the cavity height, HC, by an opening distance, Y. The increased internal dimension of the receiving cavity  220  may provide clearance  304  for the PCBA  100  to be inserted therein. Once aligned with the receiving cavity  220 , the PCBA  100  may be moved, in an insertion direction  430 , into the package  200 , while the compressive force  230  is continually applied to the package  200 . 
     The PCBA  100  may be oriented, located, or otherwise positioned inside the package  200  while the compressive force  230  is maintained, as shown in  FIG. 4C . In  FIG. 4C , the PCBA  100  is shown completely inside the receiving cavity  220 . Once the PCBA  100  is positioned inside the receiving cavity  220  relative to the front  222  and/or rear  226  of the package  200 , the compressive force  230  may be released. Releasing the compressive force  230  may allow the package to substantially return from the second state to the first state, as illustrated in  FIG. 4D . 
     Next, the package  200  may be sealed with one or more endplates  404 ,  408 , as shown in  FIGS. 4E and 4F . The endplates  404 ,  408  may substantially match the geometry or shape of an end  222 ,  226  of the package  200 . In some embodiments, the endplates  404 ,  408  may substantially follow a shape of the profile surface  204  of the package  200 . In any event, the endplates  404 ,  408  may be adhered, affixed, brazed, welded, or otherwise attached to the ends  222 ,  226  of the package  200 , respectively. It is an aspect of the present disclosure that the endplates  404 ,  408  when attached to the package  200  may hermetically seal the package  200  and, more specifically, seal the interior space of the receiving cavity  220  including the PCBA  100  from an environment outside of the receiving cavity  220 . 
     In some embodiments, one or more of the endplates  404 ,  408  may include a number of connectors, electrical interconnections, or other interconnection features  412  or passthroughs formed in a portion of the endplate  404 ,  408 . The connectors  116 A,  116 B of the PCBA  100  may be interconnected with one or more of these interconnection features  412  providing a conductive path for one or more of communication and power between the inside of the sealed receiving cavity  220  and the outside of the package  200 . As shown in  FIG. 4E , the rear endplate  408  includes a series of interconnection features  412  configured as a series of small sealed connectors  416 , pins, and/or sealable passthroughs  418 . In some embodiments, the sealed connectors  416  may be configured as one or more conductive pins disposed in respective holes of the endplate  408 , where the hole is filled with a potting material. In one embodiment, the pins may be surrounded by glass forming a glass to metal seal between the pins and the holes in the endplate  408 . In some cases, a pseudo-hermetic seal may be achieved via a passthrough connector disposed in an opening, aperture, or hole in the endplate  408 , the passthrough connector sealed in the opening, aperture, or hole by one or more gaskets and/or O-rings. The completed sealable multi-surface electronics thermal conduction package with integrated electronics  400  (e.g., with endplates  404 ,  408  sealed to the package  200 , etc.) is shown in the perspective view of  FIG. 4F . 
     In some embodiments, the operations of assembly described herein may be reversed to rework or disassemble the package  200  and/or remove or replace the PCBA  100  from the package  200 . 
       FIG. 5A  shows a perspective view of a sealable multi-surface electronics thermal conduction package  500  in accordance with embodiments of the present disclosure. The package  500  show in  FIGS. 5A-5D  may include similar, if not identical, features to those described in conjunction with the package  200  shown in  FIGS. 2A-2C . As can be appreciated, the description of the package  200 , or the assembly of the PCBA  100  in the package  200 , may apply to the package  500  shown in  FIGS. 5A-5D , and vice versa. 
     The package  500  may comprise a body including a profile, or extrusion, surface  504  and shape having a first end  508 A, a second end  508 B, a first contact surface  512 A (not shown in  FIG. 5A ), a second contact surface  512 B, and a hollow space, or electronics receiving cavity,  520  disposed therebetween. The package  500  may include a number of heat sink elements  516  configured to transfer thermal energy from a surface of the body (e.g., inside the receiving cavity  520 , etc.) to an environment surrounding the body. The heat sink elements  516  may be configured as straight fins, protrusions, pins, flared fins, etc., and/or combinations thereof. In some embodiments, the heat sink elements  516  may extend along a length of the package  500 , for example, from the front  522  (e.g., at the profile surface  504 ) to the rear  526  of the package  500 . 
     In some embodiments, the package  500  may include one or more controlled bend regions, areas, or flexures,  524 . As shown in  FIGS. 5A-5D , the package  500  may include symmetrical sets of flexures  524  disposed about a center  544  of the package  500 . In some embodiments, and as shown in  FIG. 5B , the package  500  may be centerline symmetrical about center planes passing through the center  544  of the package  500 . For instance, the package  500  may be symmetrical about the YZ-plane running through the center  544  of the package  500  and/or symmetrical about the XZ-plane running through the center  544  of the package  500 . The flexures  524  may be shaped such that a force  530  applied to the first and/or second contact surfaces  512 A,  512 B of the package  500  displaces the upper and lower portions  506 A,  506 B of the package  500  in a direction (e.g., the Y-axis direction) away from the center of the package  500 . The orientation of the flexures  524  in the package  500  may provide a linear and/or substantially orthogonal translation of the upper and lower portions  506 A,  506 B from the center  544  of the package  500 . Among other things, this linear movement may allow the internal heat contacting surfaces of the package  500  (e.g., the surfaces disposed inside the receiving cavity  520 , etc.) to move such that they may remain substantially parallel (e.g., to one another) and/or substantially orthogonal to the first and/or second contact surfaces  512 A,  512 B of the package  500 . 
     In some embodiments, the package  500  may include one or more PCB substrate channels  532 . The PCB substrate channels  532  may be sized to receive and locate the PCB substrate  104  inside the receiving cavity  520  of the package  500 . In some cases, the PCB substrate channels  532  may capture one or more edges of the PCB substrate  104 , preventing the PCBA  100  from moving in the Y-axis direction inside the receiving cavity  520 . The PCB substrate channels  532  may be sized to allow some movement of the PCBA  100  along the X-axis inside the receiving cavity  520  and/or allow the sides  508 A,  508 B of the package  500  to move relative to the PCBA  100  when compressed and/or released. 
     The package  500  may include one or more end-of-travel (EOT) stops  536 ,  540  to prevent over-flexing of the flexures  524  (e.g., where, without the stops, squeezing the package  500  could force the flexures  524  past their elastic range, etc.) during assembly and/or disassembly. In some embodiments, these EOT stops  536 ,  540  may be built into the profile  504 , body, extruded shape, and/or other portion of the package  500 . In one embodiment, a compression EOT stop  536  may be built into a portion of the heat transfer contacting surfaces adjacent to the first and second sides  508 A,  508 B of the package  500 . This compression EOT stop  536  may serve to resist movement of the sides  508 A,  508 B of the package  500  from compressing beyond a predefined amount or distance by, for example, contacting an internal portion of the sides  508 A,  508 B of the package  500  at a maximum compression (e.g., a compression amount determined to provide ample clearance  304  for inserting the PCBA  100 , etc.). In some embodiments, a vertical displacement EOT stop  540  may prevent the upper and lower portions  506 A,  506 B from extending outwardly from the center  544  of the package  500  beyond a predefined amount or distance by, for example, contacting an internal portion of the upper and lower portions  506 A,  506 B of the package  500  at a maximum displacement (e.g., a displacement amount determined to provide ample clearance  304  inside the receiving cavity  520  for inserting the PCBA  100  without restriction, etc.) 
     Similar to the package  200  described in conjunction with  FIGS. 2A-C , the package  500  may be made from plastic, metal, carbon fiber, linen, composites, epoxy resin, etc., and/or combinations thereof. In one embodiment, the material of the package  500  may be thermally conductive. Thermally conductive material may provide a thermal path from an interior space  520  of the package  500  to an environment outside the package. This thermal path may serve as the path by which heat can be transferred from electronics contained inside the package  500 . Examples of thermally conductive materials may include, but are in no way limited to, steel, titanium, aluminum, copper, tin, nickel, iron, etc., alloys thereof, and/or combinations thereof. The package  500  may be machined, wire electrical discharge machined (EDM), formed, molded, cast, extruded, etc., and/or combinations thereof. In one embodiment, the material of the package  500  may be extrudable and thermally conductive. One example of an extrudable and thermally conductive material is aluminum. In any event, the package  500  may be designed such that the profile surface  504  defines a shape corresponding to at least one shape of an extrusion die used to create the package  500 . In this example, the package  500  may be formed by heating and softening a billet of extrudable material (e.g., aluminum, etc.), forcing the billet of extrudable material through one or more extrusion dies (e.g., including the features, or inverse features, of the profile shape  504 , etc.), cooling the extruded material as it exits the one or more extrusion dies, and then cutting the extruded material to length. Once extruded and cut to length, the body can be deburred, cleaned, machined, and/or finished (e.g., coated, anodized, nickel plated, etc.). The extruded body provides a cost-effective and integral, one-piece, housing for the sealable multi-surface electronics thermal conduction package  500 . 
       FIGS. 5B  shows a front elevation view of the sealable multi-surface electronics thermal conduction package  500  of  FIG. 5A . As provided above, the package  500  may be centerline symmetrical, for example, along a centerline running through the center  544  of the package  500  along the X-axis and/or along a centerline running through the center  544  of the package  500  along the Y-axis. The package  500  shown in  FIG. 5B , may correspond to a first, unflexed, or normal state including a receiving cavity  520 , configured as a hollow space in the center of the package  500 . The package  500  may have a cavity height, HC, as previously described in conjunction with  FIGS. 2A-2C . The cavity height, HC, may be defined as a distance between a first interior surface of the package  500  and a second opposing interior surface of the package  500  along the Y-axis. This cavity height, HC, may remain substantially the same along the X-axis direction from a position adjacent to the first end  508 A of the package  500  to a position adjacent to the second end  508 B of the package  500 . Additionally or alternatively, the cavity height, HC, may remain substantially the same along the length of the package (e.g., along the Z-axis direction). In some embodiments, the cavity height, HC, may be sized to substantially match the overall height, HP, of the PCBA  100  (see, e.g.,  FIG. 1C ). In one embodiment, the cavity height, HC, in the unflexed state may be undersized, or sized less than the overall height, HP, of the PCBA  100 , by an amount to provide a clamping, or holding, force on any electronics (e.g., the PCBA  100 , etc.) disposed inside the receiving cavity  520 . In another embodiment, the cavity height, HC, may be oversized in the unflexed state, or sized greater than the overall height, HP, of the PCBA  100 , by an amount to allow a thermal interface material to be inserted between any inserted electronics (e.g., the PCBA  100 , etc.) and the interior surfaces of the receiving cavity  520 . 
       FIGS. 5C and 5B  show front elevation views of the package  500  during assembly stages inserting electronics, such as the PCBA  100 , into the receiving cavity  520 . In  FIG. 5C , the package  500  is shown in the second, or flexed, state. In particular, as the sides  508 A,  508 B of the package  500  are compressed, or squeezed, together (e.g., toward the center  544 ) causing the upper and lower portions  506 A,  506 B of the package  500  to move outwardly, from the center  544 , and away from one another, in a linear direction  550  along the Y-axis. While in the flexed state, the applied force  530  holds, or maintains, the package  500  in an “open” configuration where the receiving cavity has an increased cavity height, (HC+Y). In the second state, the increased cavity height, (HC+Y) provides clearance  304  around the heat generating elements  108 A-D and/or other electronic components of the PCBA  100 . The clearance  304  allows the PCBA  100  to be inserted into the receiving cavity  520  of the package  500 . In some embodiments, and while in the second state, the clearance  304  may allow the PCBA  100  to be inserted into the receiving cavity  520  of the package  500  without any interference or restriction between the PCBA  100  and the package  500 . As shown in  FIG. 5C , the clearance  304  provided by the displacement of the upper and lower portions  506 A,  506 B of the package  500  is the same at any point along the heat generating elements  108 A-D. For example, the clearance  304  provides a space between the heat emitting surfaces  110 A-D of the heat generating elements  108 A-D and the substantially parallel internal heat contacting surfaces of the receiving cavity  520 . 
     In  FIG. 5D , the package  500  is shown in the first, or substantially unflexed, state. As described above, the package  500  may be unflexed (e.g., having no applied force  530  flexing the package  500 , etc.) but may provide a clamping force against the heat generating elements  108 A-D holding the PCBA  100  in place inside the receiving cavity  520  of the package  500 . As shown in  FIG. 5D , at least one interior surface of the upper portion  506 A of the package  500  is contacting the upper heat generating elements  108 A-B at thermal contact areas  308 , while at least one interior surface of the lower portion  506 B of the package  500  is contacting the lower heat generating elements  108 CA-D at opposing thermal contact areas  308 . The interior surfaces of the receiving cavity  520  may be in contact, or coplanar, with the heat emitting surfaces  110 A-D of the heat generating elements  108 A-D. In some embodiments, a thermal interface material (TIM) may be disposed between the at least one interior surface of the receiving cavity  520  and the heat generating elements  108 A-D. The TIM may be a thermally conductive grease, tape, adhesive, or other thin material configured to provide an effective thermal path (e.g., a thermal coupling, etc.) between the heat generating elements  108 CA-D of the PCBA  100  and the material of the package  500 . 
       FIG. 6  is a flow diagram of a method  600  for assembling electronics in a sealable multi-surface electronics thermal conduction package  200 ,  500  in accordance with embodiments of the present disclosure. While a general order for the steps of the method  600  is shown in  FIG. 6 , the method  600  can include more or fewer steps or can arrange the order of the steps differently than those shown in  FIG. 6 . Generally, the method  600  starts with a start operation  604  and ends with an end operation  632 . The method  600  can be executed as a set of computer-executable instructions executed by an assembly machine (e.g., robotic assembly system, automation assembly system, etc.) and encoded or stored on a computer readable medium. Hereinafter, the method  600  shall be explained with reference to the components, devices, assemblies, environments, etc. described in conjunction with  FIGS. 1-5D . 
     The method  600  may begin at step  604  and continue by providing a thermal control package, for example, the package  200 ,  500  (step  608 ). In some embodiments, the provided package  200 ,  500  may be cleaned, deburred, coated, plated, and/or finished. Next, the method  600  continues by positioning an electronics assembly, for example, a PCBA  100  relative to the package  200 ,  500  (step  612 ). In some embodiments, positioning the PCBA  100  relative to the package  200 ,  500  may include aligning the PCBA  100  with the receiving cavity  220 ,  520  of the package  200 ,  500 . Steps  608  and  612 , providing the package  200 ,  500  and positioning the PCBA  100  relative to the package  200 ,  500  may be provided as shown and described in conjunction with  FIG. 4A  above. 
     Once the PCBA  100  is aligned with the receiving cavity  220 ,  520 , the package  200 ,  500  may be compressed by applying at least one compressive force  230 ,  530  to the sides  208 A,  208 B,  508 A,  508 B of the package  200 ,  500  (step  616 ). As described above, the compressive force  230 ,  530  may open a dimension of the receiving cavity  220 ,  520  to receive the PCBA  100 . In one embodiment, the package  200 ,  500  may be compressed via a vise, gripper, or other device. The compression device may be screw-actuated, pneumatically-actuated, hydraulically-actuated, etc., and/or combinations thereof. While the package  200 ,  500  is compressed, expanding a dimension (e.g., height, HC) of the receiving cavity  220 ,  520 , the PCBA  100  may be inserted into the receiving cavity  220 ,  520  without restriction (step  620 ). In some embodiments, while the package  200 ,  500  is maintained in the second (compressed/flexed) state, the position of the PCBA  100  may be adjusted inside the package  200  (e.g., along the Z-axis direction, etc.). This adjustment may ensure that the ends  122 ,  126  of the PCBA  100  are disposed between, and not extending past, the ends  222 ,  226 ,  522 ,  526  of the package  200 ,  500 . These steps  616 ,  620  may correspond to the steps illustrated and described in conjunction with  FIGS. 4B and 4C  above. 
     When the PCBA  100  is properly positioned inside the package  200 ,  500 , (e.g., inside the receiving cavity  220 ,  520 , etc.) the method  600  may continue by releasing the compressive force  230 ,  530  from the sides  208 A,  208 B,  508 A,  508 B of the package  200 ,  500  (step  624 ). Releasing the force  230 ,  530  allows the elastic energy of the package  200 ,  500  stored in, for example, the flexures  224 ,  524  to be converted into kinetic energy moving the package from the second, flexed, state to the first, unflexed, state. This elastic movement allows the package  200 ,  500  to automatically return to a substantially unflexed state without requiring any application of a force external to the material of the package  200 ,  500 . 
     Next, the method  600  may proceed by attaching the endplates  404 ,  408  to the package  200 ,  500  (step  628 ). The endplates  404 ,  408  may be adhered, affixed, brazed, welded, or otherwise attached to the ends  222 ,  226 ,  522 ,  526  of the package  200 ,  500 , respectively. It is an aspect of the present disclosure that the endplates  404 ,  408  when attached to the package  200  may hermetically seal the package  200 ,  500  and, more specifically, seal the interior space of the receiving cavity  220 ,  520  including the PCBA  100  from an environment outside of the receiving cavity  220 ,  520 . In some embodiments, (e.g., prior to attaching the endplates  404 ,  408  to the package  200 ,  500 ) the connectors  116 A,  116 B of the PCBA  100  may be interconnected to the one or more interconnection features  412  disposed on at least one of the endplates  404 ,  408 . This interconnection may provide a conductive path for one or more of communication and/or power between the inside of the sealed receiving cavity  220 ,  520  and the outside of the package  200 ,  500 . 
     In some embodiments, one of the endplates  404 ,  408  may be attached to the package  200 ,  500  before the other of the endplates  408 ,  404  is attached to the package  200 ,  500 . After one of the endplates  404 ,  408  is attached to the package  200 ,  500 , the receiving cavity  220 ,  520  of the package  200 ,  500 , specifically the areas in between the interior surfaces of the receiving cavity  220 ,  520  and the surfaces of the PCBA  100  may be filled with a material. The material may be a gas, a dielectric material, a thermally conductive material, an epoxy potting compound, etc., and/or combinations thereof. The material may provide protection of the components (e.g., electronic components, PCBA  100 , etc.) inside the receiving cavity  220 ,  520 . In one embodiment, the material may provide enhanced thermally conductive pathways between the various components of the PCBA  100  and the interior surfaces of the receiving cavity  220 ,  520 . The material may be inserted as a fluid that, when cured, hardens in the open spaces between the PCBA  100  and the interior surfaces of the receiving cavity  220 ,  520 . The material can secure the components of the PCBA  100  in place inside the receiving cavity  220 ,  520 , and relative to one another, providing enhanced shock resistance and protection from failures due to separation of components from the PCBA  100 . In some embodiments, the material inserted may serve to prevent corrosion of the electronic components inside the receiving cavity  220 ,  520  (e.g., providing an inert reactive environment, etc.). Once filled and/or cured, the other endplate  408 ,  404  may be attached to the opposite end of the package  200 ,  500  sealing the PCBA  100  inside the receiving cavity  220 ,  520 . In any event, attaching the endplates  404 ,  408  and sealing the package  200 ,  500  forming the complete sealable multi-surface electronics thermal conduction package with integrated electronics  400  may correspond to the steps illustrated and described in conjunction with  FIGS. 4E and 4F  above. The method  600  ends at step  632 . 
     It is an aspect of the present disclosure that a complete sealable multi-surface electronics thermal conduction package with integrated electronics  400  may be reworked, disassembled, or otherwise modified. In this case, the steps described in conjunction with  FIG. 6  may be reversed to open the integrated package  400 . For example, disassembling at least a portion of the integrated package  400  may include first detaching one or more of the endplates  404 ,  408  from the package  200 ,  500  (e.g. the reverse of step  628 ). This detachment may include cutting, machining, or otherwise separating at least one of the endplates  404 ,  408  from the body of the package  200 ,  500 . Once at least one of the endplates  404 ,  408  has been removed, the package  200 ,  500  may be compressed to release the PCBA  100  from the receiving cavity  220 ,  520  (e.g., the reverse of step  624 ). The reverse method may continue by removing the PCBA  100 , releasing the compressive force from the package  200 ,  500 , and separating the parts making up the PCBA  100  and package  200 ,  500 . 
     In the event that the PCBA  100  is to be replaced, the reverse method may be performed up to the point that the PCBA  100  is separated from the package  200 ,  500  and then the method  600  may be repeated (e.g., at step  612 ) to insert a new PCBA  100  in the receiving cavity  220 ,  520 . The method  600  may proceed until the new PCBA  100  is sealed inside the package  200 ,  500  forming the integrated package  400  (step  628 ). 
     The exemplary systems and methods of this disclosure have been described in relation to electronics packaging and the thermal control of sealed electronics. However, to avoid unnecessarily obscuring the present disclosure, the preceding description omits a number of known structures and devices. This omission is not to be construed as a limitation of the scope of the claimed disclosure. Specific details are set forth to provide an understanding of the present disclosure. It should, however, be appreciated that the present disclosure may be practiced in a variety of ways beyond the specific detail set forth herein.
