Compliant battery supports for device testing

Compliant supports hover a battery above pressure sensitive adhesive (PSA) when testing a computing device and before the battery is bonded to an enclosure. The compliant supports are placed along a surface of the enclosure such that at least a portion of each of the compliant supports extends above the PSA. The compliant supports apply an upwards force on the battery to maintain a gap between the battery and the PSA. After electrical testing of the computing device, the battery is brought into contact with the PSA while retaining at least one of the compliant supports in the enclosure. In some embodiments, a downwards force is applied to the battery to overcome the upwards force from the compliant supports.

BACKGROUND

Mobile computing devices provide various functionality in a limited device space or form factor. In particular. such devices are thin and light. In some devices, pressure sensitive adhesive (PSA) is used to hold components in a device enclosure or housing. For example, the battery is bonded directly to the device enclosure using the PSA. After bonding the battery to the device enclosure, functional testing is performed on the device. If problems are detected during the testing, it becomes difficult with the existing systems to remove the battery and complete repairs without deforming or damaging the battery, device enclosure, or other components in the device due to the PSA bond. Thus, with the existing systems, the same battery, enclosure, or other components in the device become unusable at least for safety reasons and must be discarded. As such, the existing systems have a high cost of re-work when there are failures that require removal of the battery or components routed under the battery.

To overcome this problem, some existing system affix the battery to the mobile device enclosure using removable release liners or removable fixtures to prevent the battery from contacting the PSA during testing. In such cases, temporary adhesive may be used to attach the battery to the fixtures. However, removing the fixtures after testing and bonding the battery to the device enclosure via the PSA are time-consuming tasks for completion by skilled operators. Further, there is a risk of the battery connection of the existing systems becoming partially or fully disconnected when attempting to perform repairs to the device after testing, at least because the battery is not in its final position while on the fixtures and there is no mechanism allowing movement of the battery while on the fixtures. In some cases, the battery flexible printed circuit (FPC) is made longer so that the battery can be lifted higher while removing the release liners or the fixtures. However, using a longer battery FPC adds to the cost of the product. As such, with the existing systems, removing the battery to correct errors detected during testing entails skilled operations with high material and labor costs.

SUMMARY

In embodiments of the disclosure, pressure sensitive adhesive (PSA) is applied on a surface of a battery enclosure of a computing device. One or more compliant supports are placed along the surface of the battery enclosure such that at least a portion of each of the compliant supports extends above the PSA. The compliant supports apply an upwards force to hover a battery above the PSA while preventing the battery from coming in contact with the PSA. The compliant supports compress and/or collapse to enable the battery to bond to the battery enclosure via the PSA. For example, a downwards force may be applied to the battery to overcome the upwards force to bond the battery to the PSA while retaining at least one of the one or more compliant supports.

DETAILED DESCRIPTION

Referring to the figures. embodiments of the disclosure enable positioning a battery of a computing device to prevent contact with pressure sensitive adhesive (PSA). In some embodiments, compliant supports are disposed along a battery enclosure to hold the battery in connection with a battery connector for functional testing of the computing device. The compliant supports compress slightly when the battery is placed on the compliant supports, and produce an upward force (e.g., a first force) to support the battery above the PSA as shown, for example, inFIG. 6.

Aspects of the disclosure enable the battery to be placed in a location that is proximate or otherwise near to the desired final location of the battery in the battery enclosure of the computing device. The compliant supports further enable translational movement of the battery in X and Y directions, as well as rotational movement in a Z direction. This movement capability imparts an ability to maneuver the placed battery to re-position it for connection with a battery connector in the battery enclosure. Further, in some embodiments, none of the compliant supports are removed during final fitment of the battery after testing. For example, a pre-defined amount of pressure is applied above the battery to produce a downwards force (e.g., a second force) that overcomes the upwards force exerted by the compliant supports. The battery then comes into contact with the PSA for bonding to the battery enclosure without removing any of the compliant supports. In other embodiments, at least one, but potentially not all, of the compliant supports are removed during final fitment of the battery into the battery enclosure.

Aspects of the disclosure enable functional testing of the computing device at a production facility without the battery being bonded to the battery enclosure using PSA, and without using any removable release liners and/or removable fixtures to prevent the battery from contacting the PSA during the testing. If, during the functional testing, any failures are encountered and some components of the computing device need repair or replacement, the battery may be easily removed without any damage and/or deformation to the battery and/or the battery enclosure. Further, the battery enclosure as well as any other components do not suffer any damage during the process of removing the battery. For example, after rectification of any failures detected during testing, the same battery, the battery enclosure, and/or the components that did not need any rectification may still be used in the computing device. In this manner, aspects of the disclosure reduce the cost of repairs at least because the battery may be easily removed to allow access to other components under the battery upon detection of failures therein.

Additionally, because no removable fixtures are used for the temporary fitment of the battery for device testing in some embodiments, no time-consuming, skilled, and potentially damaging operations need to be performed.

The battery may be bonded to the battery enclosure using the previously-applied PSA after the functional testing (e.g., if no rectification is desired or needed during the functional testing). In some embodiments, functional testing using the battery is performed after other components have been fitted in the computing device and tested. If, during the functional testing with the battery engaged with the compliant supports, all the parameters of the computing device are found to be within acceptable limits, then the battery may be bonded to the battery enclosure using the PSA that was pre-applied to the battery enclosure. In this embodiment, a pre-defined amount of pressure (e.g., 20 pounds per square inch) is applied on the battery to press it down and come in contact with the pre-applied PSA. The pressure is maintained for a pre-defined period of time (e.g., 20 seconds). The applied pressure overcomes the upward (or outward) force of the compressed compliant supports and compresses the compliant supports (e.g., further) to shrink the compliant supports and to allow the battery to be bonded to the device enclosure via the PSA. When no problems are encountered during functional testing, the operations of functional testing and final assembly may be dovetailed.

Referring toFIG. 1, an exemplary schematic diagram illustrates PSA104placed at the designated location in a battery enclosure102of a computing device. The PSA104may, in some embodiments, have a top release liner and a bottom release liner that are removed when the PSA104is inserted in, or applied to, the battery enclosure102.FIG. 1further illustrates a left ground plane106and a right ground plane108. The left and right ground planes may, for example, be radio frequency (RF) ground planes. In some embodiments, only the ground plane left106and the PSA104bond the battery304to the battery enclosure102.FIG. 1also shows battery connector110to which the battery304is connected during functional testing and thereafter.

The computing device may include, but is not limited to, various mobile computing devices such as mobile phones, personal digital assistants, pagers, tablets, messenger devices, hand-held computing devices, pocket translators, e-books, bar code readers. smart phones, computing pads, netbooks. gaming devices, portable media players, head-mounted devices, and the like. The computing device may also include less portable devices such as desktop personal computers, kiosks, tabletop devices, industrial control devices, wireless charging stations, and electric automobile charging stations.

Referring next toFIG. 2, an exemplary schematic diagram illustrates four compliant supports202placed in designated locations in the battery enclosure102. However, less than or more than four compliant supports may be used. The compliant supports202, having a quadrilateral shape, are shown inFIG. 2as rectangles. However, aspects of the disclosure are operable with various other shapes and sizes of the compliant supports. Further, exemplary items may be visible or invisible in the battery enclosure102. For example,FIG. 2depicts components204that are earmarked to be put under the battery304when fitted. The figure also illustrates the PSA104, placed in its designated location, to be used for final bonding of the battery with the battery enclosure102. The battery enclosure102has been fitted with operational components for functional testing except the battery304. The battery enclosure102is, therefore, ready for placement of the battery304on the compliant supports202for functional testing.

The battery304, when engaged with the compliant supports202, is supported and attachable to the compliant supports202but above the PSA104(e.g., without touching it). For example, the compliant supports202are firm enough to hold up the weight of the battery304to prevent contact between the battery304and the PSA104, but soft enough to not exert significant repelling force when compressed (e.g., when the battery304bonds to the PSA104). Significant repelling force may reduce battery bond strength during reliability testing. An optimum gap, such as 0.2-0.6 millimeters (mm) is maintained between the PSA104and the battery304during functional testing, in some embodiments. This gap is a function of different factors, including the weight of the battery, the dimensions and shape of the compliant supports, the material of the compliant supports, the quantity of compliant supports used, the density of the compliant supports and the compression modulus of the compliant supports.

By the terms “supported attachable” or “supported connectable” or “supported insertable”, the battery304may be temporarily attached, supported, connected, or otherwise placed in the battery enclosure102in such a way that the risk of unintentionally separating the battery304from the battery enclosure102is minimal. However, the battery304and the compliant supports are attached in such a way that they may be separated when desired, and the battery may be removed from the battery enclosure102without damaging the battery304, the compliant supports, the battery enclosure102, and/or other components.

FIG. 2shows an exemplary quantity of four compliant supports202that may be used in some embodiments. However, more than or less than four pieces of the compliant supports may be used. Further, while all the compliant supports may be identical in some embodiments, each or some of the compliant supports may have different shapes, sizes, dimensions, material, and/or other properties in other embodiments. The compliant supports202are shown outside the PSA104inFIG. 2. However, one or more of the compliant supports202may be arranged on the PSA104. Further, while the PSA104is shown as one piece inFIG. 2, the PSA104may be comprised of a plurality of pieces of PSA.

FIG. 3is an exemplary schematic diagram illustrating the battery304, when placed proximate to its final designated location in the battery enclosure102after successful testing (or completion of repairs).FIG. 3also shows other exemplary locations and components such as a component enclosure306and a battery connector110. The battery304is axially translatable in the X and Y directions, and rotationally moveable within the battery enclosure102in Z direction. Even though the battery304is placed proximate to its final designated position in this example, it may not align with datum lines marked in the mobile computing device housing. The datum lines indicate the final designated position of the battery304for connection with the battery connector110. Because the compliant supports have flexibility (e.g., compliance) and the battery304is not touching the PSA104, aspects of the disclosure enable the battery304to have translational and rotational maneuverability. This maneuverability enables the battery to be aligned with the datum lines in the battery enclosure102, and be positioned above or otherwise near its designated location before final bonding with the PSA104.

FIG. 4A to 4Cdepict an exemplary embodiment of the compliant supports202. In this implementation of the compliant supports202, a quadrilateral piece of foam406is used as a compliant support. The exemplary material used is Nitto Denko SCF100 available from Nitto Denko of Japan. The length and breadth of the compliant supports202is “a” and “b” respectively. The thickness of the compliant supports202is “c.” The compliant supports202in this implementation have double-sided adhesive tape408applied to the compliant supports202. Use of the double-sided adhesive tape408facilitates temporarily connecting (e.g., sticking) the compliant supports202to the battery enclosure102, and temporarily connecting the battery304with the compliant supports202for and during functional testing. In one embodiment, a Nitto Denko double-sided adhesive tape is used for this purpose.

The range of the dimensions “a”. “b”. and “c” may vary substantially depending upon the size of the computing device, the size, shape, weight and type of the battery304, the battery discharge rate during functional testing, the temperature rise of the battery304and the battery enclosure102, the space available in the battery enclosure102, and other factors. In an exemplary embodiment, length “a” is 1.5 centimeters (cm), breadth “b” is 0.5 cm, and thickness “c” is 0.8 mm (when uncompressed). The thickness of the PSA104is an example one of the criteria to determine “c”. However, substantial variations in dimensions are possible in other embodiments of the disclosure without causing any problem in mechanical assembly and functional testing. For example, a compliant support may be non-rectangular, and may have any shape, irregular or regular.

In the exemplary case where the material of the compliant supports202is Nitto Denko SCF 100 and the values of “a”, “b” and “c” are 1.5 cm, 0.5 cm, and 0.1 cm respectively, exemplary calculations for the gap between the PSA104and the battery304and the upwards force exerted by the compressed compliant supports202are next described. The compressive strength of Nitto Denko SCF 100 foam at 50% compression is approximately 1.2 N/cm2. The area of each piece of the foam is shown in Equation (1) below.
1.5×0.5=0.75 cm2(1)

The area of four foam pieces is shown in Equation (2) below.
4×0.75=3 cm2(2)

Upwards force exerted by the foam pieces at 50% compression is shown in Equation (3) below.
1.2×3=3.6 N  (3)

The thickness of PSA104is 0.2 mm. At 50% compression, the available thickness of the foam is 0.5 mm. The gap between PSA104and battery304is shown in Equation (4) below, if a force of 3.6 N is applied.
0.5−0.2=0.3 mm  (4)

Assuming the weight of the battery at 80 grams is approximately 0.8 N, and assuming a linear compression rate of the foam, the foam pieces are compressed as shown in Equation (5) below.
(0.8/3.6)×0.5=0.13 mm  (5)

Hence, the actual gap between the battery and the PSA104in this example is shown in Equation (6) below.
1.0−0.13−0.2=0.67 mm  (6)

However, other gaps are contemplated. For example, a gap of 0.2 mm between the battery and the PSA104is sufficient to keep the battery above (e.g., not contacting) the PSA104during testing, in some embodiments. Further, in some embodiments, when the battery304bonds to the PSA104, the foam is compressed to 80% with rebound pressure against the bonded battery low enough to not weaken the integrity of the bond.

The above exemplary calculations show that a wide range of dimensions (e.g., thicknesses) of the compliant supports may be used with the disclosure. The Nitto Denko SCF100 foam is available at least in thickness varying from 0.5 to 1.0 mm. Accordingly, any suitable thickness may be chosen based on various factors, such as the weight of a given battery, the space available in a given battery enclosure, and suitable values for dimensions “a”, and “b”, and the quantity of foam pieces to be used as the compliant supports. Any other suitable foam (e.g., Nikko Denko SCF200, Nikko Denko SCF400, Nikko Denko SCF T100 or Nikko Denko P1500, or similar foams from other manufacturers) may be used to fabricate the compliant supports202.

Further, other suitable shapes, apart from the rectangular shape already described herein, may be used. For example, as shown inFIGS. 5A-5C. circular discs may be used. The circular disks may be punched from a sheet of foam, or as available pre-made from a supplier. The quantity of pieces of the compliant supports to be used may be selected at least based on the weight and size of the battery, the temperature rise of the battery and the battery enclosure during testing, the space available in the battery enclosure, the material of the foam, and the production expediency.

FIGS. 5A-5Cschematically illustrate punching circular discs504from a sheet of foam502to minimize wastage. Thickness of the disc “c” and the diameter of the disc “d” may be suitably chosen, based on at least the above-enumerated factors, to provide adequate gap and upwards force to support the battery304during testing.

FIG. 6is an exemplary schematic diagram illustrating usage of the compliant supports202supportably insertable inside the battery enclosure102. The compliant supports202are attached to the battery enclosure102temporarily using, for example, double-sided adhesive tape408. The battery304is placed proximate to its designated location inside the battery enclosure102above the compliant supports202. The compliant supports202exert sufficient upwards force to support the battery above the PSA104. In this condition, there is adequate gap between the PSA104and the battery. The battery is rotationally moveable and axially translatable to align with datum lines and to mate with the battery connector110. The battery304temporarily attaches to, or otherwise engages, the compliant supports202such that there is little risk of unintentionally separating the battery304from the compliant supports202or the battery enclosure102. However, if during functional testing of the computing device, some rectifications or other repairs to the device are desired, the battery may be removed from the battery enclosure102without any damage to the battery304, the battery enclosure102and/or the operational components already installed inside the battery enclosure102.

FIG. 7schematically illustrates an exemplary battery installation inside the battery enclosure102after satisfactory functional testing (e.g., no repairs needed). Once the functional testing has been satisfactorily completed, the battery304may be finally fitted inside the battery enclosure102using the PSA104. In some embodiments, for battery304fitment, a pre-defined amount of downward force is applied above the battery304for a pre-defined period of time. The compliant supports202compress and the battery contacts the PSA104for a period of time (e.g. 20 seconds) that is sufficient to produce a relatively permanent, or semi-permanent bond between the PSA104and the battery304. The upward force exerted on the battery304by the compliant supports202when compressed is less than the bonding force produced between the PSA104and the battery304such that the battery304remains bonded to the PSA104when the compliant supports202are compressed. Accordingly, the battery304is bonded to the battery enclosure102through the agency of the PSA104.

A wide variety of shapes, sizes, thicknesses and material may be used to fabricate compliant supports. A few exemplary shapes are shown inFIG. 8throughFIG. 11. For example,FIG. 8depicts spherical-shaped compliant supports802, whileFIG. 11shows oval-shaped compliant supports1102. These shapes facilitate translation and rotation of the battery304in situ. The spherical- and oval-shaped compliant supports may be made of suitable plastic or rubber material and filled with air, a suitable gel or other material. The spherical- and oval-shaped compliant supports are strong enough to support the weight of the battery. However, when pressed, the compliant supports802and1102break, thus allowing the battery304to be pressed to the PSA104as described above for bonding. In an embodiment, the gel may be an adhesive gel that comes in contact with the PSA104and the battery304and provides further bonding between the battery304and the PSA104.

FIG. 9andFIG. 10show compliant supports fabricated from foam-like plastic material shaped into the form of legs that support the battery weight during testing, but flatten out under pressure and allow the battery304to be bonded to the battery enclosure102using the PSA104. The shapes shown inFIGS. 8-11are merely representative and a plurality of other shapes, sizes and materials are within the scope of the disclosure.

In some embodiments, a suitable adhesive is used to temporarily attach the compliant supports to the battery enclosure102and the battery304to the compliant supports. However, as discussed above, it is possible to remove the battery304from the battery enclosure102without any damage to any component.

FIG. 12is an exemplary schematic diagram illustrating usage of only one compliant support1202supportably inserted inside the battery enclosure102. In this exemplary embodiment, a single compliant support of suitable material with suitable size and shape, as described herein, is placed proximate to a center (e.g., central location) of the battery enclosure102. The compliant support1202provides adequate upwards force to support the battery inside the battery enclosure102during functional testing. As discussed earlier, after satisfactory functional testing, suitable pressure is applied over the battery304to overcome the upwards force, compress the compliant support1202, and bring the battery in contact with the PSA104for a pre-determined time period to bond the battery304to the battery enclosure102. The duration of the pre-determined time period is dependent, at least, upon the particular PSA104applied to the battery enclosure102.

FIG. 13is an exemplary schematic diagram illustrating usage of multiple compliant supports supportably insertable inside the battery enclosure102. In this embodiment, multiple compliant supports1302are placed at suitable locations inside the battery enclosure102. Further, another compliant support1304is placed proximate to a central location inside the battery enclosure102. Compliant supports1302and1304may be of different shapes, sizes and materials. In this embodiment, after satisfactory functional testing, one or more of the compliant supports1302may be removed, while other compliant supports1304may be kept inside the battery enclosure102before bonding the battery304to the battery enclosure102using the PSA104.

FIG. 14illustrates a flowchart describing a method of assembling and electrically testing a computing device in accordance with some of the described embodiments. As shown inFIG. 14, the method begins at1402. At1404, a battery is placed on top of a plurality of compliant supports extending above PSA104applied to a surface of a battery enclosure of the computing device, the plurality of compliant supports preventing the battery from being in contact with the PSA104. At1406, the battery is connected to a battery connector through translational and/or rotational movement of the battery via at least one of the plurality of compliant supports. At1408electrical testing of the computing device is performed. At1410, the battery is attached to the battery enclosure by pressing the battery into contact with the PSA104, wherein pressing the battery overcomes a force generated by the plurality of compliant supports and brings the battery in contact with the PSA104. At1412, the method ends.

FIG. 15illustrates a flowchart describing a process of assembling and functional testing a computing device (e.g. a mobile device) before final assembly in accordance with some of the described embodiments. The testing at this stage before final assembly assures the quality of the mobile device as shipped to distributors and dealers, while at the same time provides an opportunity for rectification or other repairs if some parameters are found outside the acceptable limits. While the flowcharts depicts a plurality of operations, additional or fewer operations may be performed for functional testing in other embodiments of the disclosure.

As shown in the flowchart, the process of functional testing and final fitment of a battery begins at1502. At1504, a mobile device assembly (MDA) fitted with all operational components for functional testing is received. At this stage of the MDA, in some embodiments, the only uninstalled operational component needed to conduct the functional testing is the battery. Before placing the battery inside the MDA, PSA104is to be applied to the MDA. To facilitate this, at1506, a bottom release liner is removed from the PSA104so that the PSA104bonds to the MDA when applying the PSA104to the designated location in the MDA. At1508, a top release liner is removed from the PSA104so that when the battery is pressed to the PSA104for a pre-defined time period, the battery bonds to the PSA104which in turn is bonded to the MDA. In one embodiment, the PSA104is procured with top and bottom release liners attached to it so that the adhesive layers are protected during transportation and storage.

At1510, compliant supports are placed at designated locations inside the MDA. The compliant supports may be of any suitable shape, size and material as described herein. In some embodiments, the compliant supports may have double-sided adhesive applied to them that facilitates temporarily sticking the compliant supports to the MDA and the battery. At1512, the battery is placed inside the MDA above the compliant supports such that it is attached to the compliant supports but has axial movability in X-Y directions and rotational capability without detaching from the MDA or the compliant supports. The battery is placed proximate to its designated location but maneuvered at1514to align it to the datum lines that are provided, in some embodiments, inside the MDA to facilitate proper placement of the battery and its connection with a battery connector already installed inside the MDA.

At1516, the battery is electrically connected to the battery connector already installed inside the MDA as a preparatory step to functional testing. At this stage, the MDA is ready for functional testing including testing of the battery in situ. At1518, complete functional testing is conducted on the MDA to ensure that all the parameters of the mobile device are within acceptable limits. If, however, some parameters are found to be not within acceptable limits, it is easy to remove the battery without any damage to any component or the battery to perform repairs because the battery has not been permanently bonded to the MDA. The battery and other component may then be re-used after the repairs.

At1520, the values of all the parameters tested during functional testing are compared to acceptable limits. If all the parameters are found to be within limits, the operation of bonding the battery to the MDA using the pre-applied PSA104is performed at1522. In one exemplary embodiment, a pressure of 20 pounds per square inch (PSI) is applied above the battery for 20 seconds. The applied pressure and the time period may have suitable tolerance (e. g+1 PSI for the applied pressure and +1 second for the time period). However, the values of tolerances for the pressure and time period for application of pressure may vary depending on the properties of the PSA104and other factors. For example, values of pressure and time period of application varying by 20% are within an acceptable range in some embodiments. However, other values are within the scope of the disclosure. In some embodiments, a suitable fixture may be used to apply pressure evenly over the entire surface of the battery. At1524, the MDA is released for further assembly operations. The functional testing and battery fitment operations end, in this example, at1532.

However, if the values of some parameters are found to be outside the acceptable limits, the faulty components are identified at1526. The battery may be kept in situ for fault-diagnosis. After fault-diagnosis, the battery is removed at1528. Because the battery is placed on compliant supports, the battery may be easily removed without incurring damage. In one embodiment, the battery may be vertically lifted and detached from the compliant supports, while leaving the compliant supports in place so that the same compliant supports may be used again. In other embodiments, while removing the battery, the compliant supports may also be removed, and new compliant supports may be used after rectification. At1530, rectification action is carried out by repairing or replacing the faulty components.

After rectification, functional testing is performed again. To facilitate functionally testing the MDA again, the operations beginning from1506or1512are performed again depending upon whether or not the compliant supports were removed during the operation of removing the battery.

FIG. 16illustrates some of the exemplary materials that may be used to fabricate the compliant supports and their properties. At1602, a general-purpose foam is shown. Other foams shown inFIG. 16are available from Nitto Denko. At1604. P1500, a flame-retardant foam is shown. At1606, SCF200, a heavy-duty foam is shown. At1608, SCF T100 that has a higher breaking strength is shown. At1610, the SCF00 that is used in an exemplary embodiment is shown. At1612, SCF400, a thin foam is shown. Depending upon the application demands, any of the above foam may be used for fabricating the compliant supports.

Aspects of the disclosure are operable with materials having various ranges of compression. For example, some embodiments have an acceptable range of compression of up to 75%.

ADDITIONAL EXAMPLES

In one embodiment, the compliant supports are in the form of breakaway supports of suitable material that support the weight of the battery, but breakaway and remain under the PSA104during bonding of the battery with the MDA after satisfactory functional testing.

In another embodiment, springs of a light, thin material are lightly attached to the MDA and the battery. The springs may be used as compliant supports to support the weight of the battery during functional testing but compress during bonding of the battery with the MDA after satisfactory functional testing.

While some embodiments have described bonding the battery304to the PSA104by pressing the battery304into the battery enclosure102and compressing the compliant supports202. other embodiments are contemplated. For example, rather than using pressure, the compliant supports202may compress, collapse, and/or disintegrate in response to the application of sound (e.g., ultrasound), light (e.g., ultraviolet light), electrical current, and/or heat. Further, the compliant supports202may be pulled from the battery enclosure102using a tool. Alternatively or in addition, the compliant supports202may be formed from self-assembling microelectromechanical systems (MEMS) or using nanotechnology.

The embodiments illustrated and described herein as well as embodiments not specifically described herein but within the scope of aspects of the invention constitute exemplary means for assembling and testing the computing device. For example, some embodiments include PSA means disposed along a surface of the battery enclosure102, compliant support means disposed along the surface with at least a portion of the compliant support means extending above the PSA means, and battery connector means for receiving the battery.

Embodiments of the disclosure are operable with any general purpose or special purpose computing system environments, configurations, or devices. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with aspects of the disclosure include, but are not limited to, mobile computing devices, personal computers, server computers, hand-held or laptop devices, multiprocessor systems, gaming consoles, microprocessor-based systems, set top boxes, programmable consumer electronics, mobile telephones, mobile computing and/or communication devices in wearable or accessory form factors (e.g., watches, glasses, headsets, or earphones), network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices. and the like.
