     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     Modern portable electronic devices are complex devices that include many complex, sophisticated components and systems that facilitate a multitude of functions. For example, tablet computers according to the instant disclosure may include touch- and/or force-sensitive displays, numerous cameras (including both front- and rear-facing cameras), GPS systems, haptic actuators, wireless charging systems, and all requisite computing components and software to operate these (and other) systems and otherwise provide the functionality of the tablet computers. To maintain the portability and usability of such devices, these systems must be physically integrated into small, thin, and lightweight devices, while also ensuring that the devices remain robust and capable of everyday use. 
       FIG.  1 A  shows an example electronic device  100  embodied as a tablet computing system, also referred to as a tablet computer. While the device  100  is a tablet computer, the concepts presented herein may apply to any appropriate electronic devices, including wearable devices (e.g., watches), laptop computers, handheld gaming devices, mobile phones, computing peripherals (e.g., mice, touchpads, keyboards), or any other device. Accordingly, any reference to an “electronic device” encompasses any and all of the foregoing. 
     The electronic device  100  includes a cover  102  (e.g., a front cover), such as a glass, glass-ceramic, ceramic, plastic, sapphire, or other substantially transparent material, component, or assembly, attached to a housing  104 . The cover  102  may be positioned over a display  103 . The cover  102  may be formed from glass (e.g., a chemically strengthened glass), sapphire, ceramic, glass-ceramic, plastic, or another suitable material. The cover  102  may be formed as a monolithic or unitary sheet. The cover  102  may also be formed as a composite of multiple layers of different materials, coatings, and other elements. 
     The display  103  may be at least partially positioned within the internal volume of the housing  104 . The display  103  may be coupled to the cover  102 , such as via an adhesive or other coupling scheme. The display  103  may include a liquid-crystal display (LCD), light-emitting diode, organic light-emitting diode (OLED) display, an active layer organic light emitting diode (AMOLED) display, organic electroluminescent (EL) display, electrophoretic ink display, or the like. The display  103  may be configured to display graphical outputs, such as graphical user interfaces, that the user may view and interact with. The device  100  may also include an ambient light sensor that can determine properties of the ambient light conditions surrounding the device  100 . The device  100  may use information from the ambient light sensor to change, modify, adjust, or otherwise control the display  103  (e.g., by changing a hue, brightness, saturation, or other optical aspect of the display based on information from the ambient light sensor). 
     The display  103  may include or be associated with one or more touch- and/or force-sensing systems. In some cases, components of the touch- and/or force-sensing systems are integrated with the display stack. For example, electrode layers of a touch- and/or force-sensor may be provided in a stack that includes display components (and is optionally attached to or at least viewable through the cover  102 ). The touch- and/or force-sensing systems may use any suitable type of sensing technology, including capacitive sensors, resistive sensors, surface acoustic wave sensors, piezoelectric sensors, strain gauges, or the like. The outer or exterior surface of the cover  102  may define an input surface (e.g., a touch- and/or force-sensitive input surface) of the device. While both touch- and force-sensing systems may be included, in some cases the device  100  includes a touch-sensing system and does not include a force-sensing system. The device  100 , using the touch- and/or force-sensing systems may be configured to detect inputs applied to the cover  102 . Such inputs include, for example, touch inputs applied by one or more fingers, a stylus, or another implement. Touch-based inputs applied using fingers, styli, or other implements may include touches, taps, single- or multi-finger gestures (e.g., swipes, pinching gestures, etc.), handwriting inputs, drawing inputs, or the like. In some cases, force sensing systems detect an amount of force associated with a touch-based input. The device  100  may take different actions based on the amount of force detected. For example, if a touch-based input (applied to a selectable element displayed on the display  103 , for example) is associated with a force that is below a threshold, the device  100  may take a first action (e.g., launch an application associated with the selectable element), and if the touch-based input is associated with a force that exceeds the threshold, the device  100  may take a second action (e.g., display a menu associated with the selectable element). Other actions are also contemplated. 
     The device  100  may also include a front-facing camera  111 . The front-facing camera  111  may be positioned below or otherwise covered and/or protected by the cover  102 . The front-facing camera  111  may have any suitable operational parameters. For example, the front-facing camera  111  may include a 12 megapixel sensor (with 1 micron pixel size), and an 80-90° field of view. The front-facing camera  111  may have fixed focus optical elements with an aperture number of f/1.8. Other types of cameras may also be used for the front-facing camera  111 . 
     The device  100  may also include one or more buttons (e.g., buttons  106 ,  108 ), switches, and/or other physical input systems. Such input systems may be used to control power states (e.g., the button  106 ), change speaker volume (e.g., buttons  108 ), switch between “ring” and “silent” modes, and the like. 
     The device  100  may also include a charging port  113  (e.g., for receiving a power cable for providing power to the device  100  and charging the battery of the device  100 ). The device  100  may also include one or more speakers and one or more microphones. The housing  104  may include audio openings to allow sound (produced by internal speakers) to exit the housing  104  and to allow an internal microphone to be acoustically coupled to the surrounding environment through an audio opening. 
     The housing  104  may be a multi-piece housing. For example, the housing  104  may be formed from multiple housing members  128 ,  130 , which are structurally coupled together via one or more joint structures  112 . The joint structure  112  may be mechanically interlocked with the housing members  128 ,  130  to structurally couple the housing members and form a structural housing assembly. Together, the housing members  128  and  130  and the joint structure  112  may define four sidewalls (and thus four exterior side surfaces) of the device  100 . Thus, both the housing members and the joint structures define portions of the exterior side surfaces of the device  100 . For example, the housing member  128  may define a first side surface the electronic device, and portions of second and third side surfaces of the electronic device. The housing member  130  may also define portions of the second and third side surfaces of the electronic device, and a fourth side surface. The housing member  130  may also define substantially all of the back exterior surface of the device  100 . The housing member  130  may be a unitary structure, such as a single piece of metal (or other suitable material), that defines portions of the back surface and two, three, or four side surfaces. (In some cases, the housing member  130  may be configured to only define a back surface of the device  100 .) 
     The housing members  128  and  130  may be formed of a conductive material (e.g., a metal such as aluminum, stainless steel, or the like), and the joint structure  112  may be formed of one or more polymer materials (e.g., glass-reinforced polymer). The joint structure  112  may include one or more molded elements. The joint structure  112  may be formed of a polymer material (e.g., a fiber-reinforced polymer). In the case where the joint structure  112  is formed of two or more molded elements, the molded elements may be formed of different materials. For example, an inner molded element may be formed of a first material (e.g., a polymer material), and an outer molded element may be formed of a second material that is different from the first (e.g., a different polymer material). The materials may have different properties, which may be selected based on the different functions of the inner and outer molded elements. For example, the inner molded element may be configured to make the main structural connection between housing members, and may have a higher mechanical strength and/or toughness than the outer molded element. On the other hand, the outer molded element may be configured to have a particular appearance, surface finish, chemical resistance, water-sealing function, or the like, and its composition may be selected to prioritize those functions over mechanical strength). 
     In some cases, one or more of the housing members  128 ,  130  (or portions thereof) are configured to operate as antennas (e.g., members that are configured to transmit and/or receive electromagnetic waves to facilitate wireless communications with other computers and/or devices). To facilitate the use of the housing members as antennas, feed and ground lines may be conductively coupled to the housing members to couple the housing members to other antenna and/or communication circuitry. Further, the joint structure  112  may be substantially non-conductive to provide suitable separation and/or electrical isolation between the housing members. The joint structure  112  may be used to tune the radiating portions, reduce capacitive coupling between radiating portions and other structures, and the like. In addition to the housing members  128 ,  130 , some or all of which may be used as antennas, the device  100  may also include various internal antenna elements that are configure to transmit and receive wireless communication signals through various regions of the housing  104 . 
     The exterior surfaces of the housing members  128 ,  130  may have substantially a same color, surface texture, and overall appearance as the exterior surfaces of the joint structure  112 . In some cases, the exterior surfaces of the housing members  128 ,  130  and the exterior surfaces of the joint structure  112  are subjected to at least one common finishing procedure, such as abrasive-blasting, machining, polishing, grinding, or the like. Accordingly, the exterior surfaces of the housing members and the joint structures may have a same or similar surface finish (e.g., surface texture, roughness, pattern, etc.). In some cases, the exterior surfaces of the housing members and the joint structures may be subjected to a two-stage blasting process to produce the target surface finish. 
     The device  100  may also include a sensor  110 . The sensor  110  may be configured to detect a presence or configuration of an accessory. For example, a foldable cover accessory may be provided for use with the device  100 . The sensor  110  may be configured to detect whether the cover accessory is in an open configuration (e.g., so the cover  102  is exposed, graphical outputs on the display  103  are visible, and the user may provide touch-based inputs on the cover  102 ). The device  100  may take different actions in response to detecting whether the cover accessory is open or closed, and/or based on detecting a transition (e.g., when the cover accessory transitions from opened to closed, or vice versa). For example, the device  100  may activate the display  103  upon detecting that the cover accessory has been opened, and deactivate the display  103  upon detecting that the cover accessory has been closed. 
     The sensor  110  may be configured to detect a component or material of the accessory cover. For example, the sensor  110  may be a Hall effect sensor, an optical sensor, a reed switch, a magnetometer, an inductive sensor, or any other suitable sensor or sensor system. In some cases, the sensor  110  (e.g., a Hall effect sensor) may detect the presence of a magnet in the cover accessory, where the magnet is positioned so that it is proximate the sensor  110  when the cover accessory is in a closed configuration. The sensor  110  may be positioned below (or behind) the display  103 , and may sense the presence of the cover accessory through the cover  102 , the display  103 , components of the touch- and/or force-sensing systems, or the like. 
       FIG.  1 B  illustrates a back side of the device  100 . The housing members  128 ,  130  and the joint structure  112  may each define part of a back surface  114  of the device  100 . The device  100  may also include a rear-facing sensor region  116 . The rear-facing sensor region  116  may include a cover member  132 , which may be set into an opening in the housing member  130 . The housing member  130  may define a raised rim  134  that surrounds the outer perimeter of the cover member  132 . The cover member  132  may overlie various types of input and output devices, including but not limited to one or more cameras, a flash, a microphone, a depth- or distance-sensing device, an ambient-light sensor, or the like. The cover member  132  may define openings in which other components may be positioned (e.g., meshes, windows, or the like), sensor windows (e.g., areas that are transparent to visible light, infrared light, or the like), or the like. 
     The device  100  may include, in or otherwise associated with the rear-facing sensor region  116 , a first camera  118 , a second camera  120 , and a flash  122 . The first camera  118  may be a super-wide angle camera having a 12 megapixel sensor and a camera lens with a first focal length (or range of focal lengths), a wide field of view (e.g., 120° FOV) optical stack with an aperture number of f/2.4, and the second camera  120  may be a wide angle camera having a 12 megapixel sensor, a second focal length (or range of focal lengths) different from the first focal length, and an aperture number of f/1.6. In some cases, the first and second cameras may have other optical properties and/or performance. For example, the first or the second camera may be a telephoto camera having a 12 megapixel sensor with a 2× optical zoom optical stack and having an aperture number ranging from f/2.0 to f/2.2. One or more of the cameras  118 ,  120  may also include optical image stabilization, whereby the camera lens is dynamically moved relative to a fixed structure within the device  100  to reduce the effects of “camera shake” on images captured by the camera. The camera may also perform optical image stabilization by moving the image sensor relative to a fixed lens or optical assembly. 
     The cameras  118 ,  120 , along with associated processors and software, may provide several image-capture features. For example, the cameras  118 ,  120  may be configured to capture full-resolution video clips of a certain duration each time a user captures a still image. As used herein, capturing full-resolution images (e.g., video images or still images) may refer to capturing images using all or substantially all of the pixels of an image sensor, or otherwise capturing images using the maximum resolution of the camera (regardless of whether the maximum resolution is limited by the hardware or software). 
     The captured video clips may be associated with the still image. In some cases, users may be able to select individual frames from the video clip as the representative still image associated with the video clip. In this way, when the user takes a snapshot of a scene, the camera will actually record a short video clip (e.g., 1 second, 2 seconds, or the like), and the user can select the exact frame from the video to use as the captured still image (in addition to simply viewing the video clip as a video). 
     The cameras  118 ,  120  may also include one or more cameras having a high-dynamic-range (HDR) mode, in which the camera captures images having a dynamic range of luminosity that is greater than what is captured when the camera is not in the HDR mode. In some cases, the cameras  118 ,  120  automatically determine whether to capture images in an HDR or non-HDR mode. Such determination may be based on various factors, such as the ambient light of the scene, detected ranges of luminosity, tone, or other optical parameters in the scene, or the like. HDR images may be produced by capturing multiple images, each using different exposure or other image-capture parameters, and producing a composite image from the multiple captured images. 
     The cameras  118 ,  120  may also include or be configured to operate according to an object detection mode, in which a user can select (and/or the device  100  can automatically identify) objects within a scene to facilitate those objects being processed, displayed, or captured differently than other parts of the scene. For example, a user may select (or the device  100  may automatically identify) a person&#39;s face in a scene, and the device  100  may focus on the person&#39;s face while selectively blurring the portions of the scene other than the person&#39;s face. Notably, features such as the HDR mode and the object detection mode may be provided with a single camera (e.g., a single lens and sensor). 
     The flash  122  is configured to illuminate a scene to facilitate capturing images with the cameras  118 ,  120 . The flash  122  may include one or more light sources, such as one or more light emitting diodes (e.g., 1, 2, 3, 4, or more LEDs). The flash  122 , in conjunction with the cameras  118 ,  120  or other systems of the device  100 , may adjust the color temperature of the light emitted by the light sources in order to match or otherwise adapt to a color temperature within a scene being captured. The device  100  may also be configured to operate the flash  122  and the shutters of the cameras  118 ,  120  to avoid consequences of flash “flicker.” For example, the device  100  may avoid capturing exposures during moments where the flash  122  is at a period of no or low illumination (e.g., which may be caused by discontinuous or pulsed operation of the LEDs). 
     The device  100  may also include, in or otherwise associated with the rear-facing sensor region  116 , a microphone  124  and a depth sensor  126 . The microphone  124  may be configured to capture audio, and may be associated with an opening in the cover member  132 . The microphone  124  and its physical integration in the device  100  are described herein with respect to  FIGS.  7 A- 7 C . The depth sensor  126  may be configured to estimate a distance between the device  100  and a separate object or target. The depth sensor  126  may include an emitter and a receiver, and may configured to emit and receive light through the material of the cover member  132 . The depth sensor  126  and its physical integration in the device  100  are described herein with respect to  FIGS.  6 A- 6 D . 
       FIG.  2 A  depicts an exploded view of a portion of the electronic device  100 . In particular,  FIG.  2 A  depicts an exploded view of a portion of the device  100  that includes the rear-facing sensor region  116  (also referred to herein simply as the sensor region  116 ). The housing member  130  may define a raised rim  134 , and the raised rim  134 , in turn, defines a sensor assembly hole  200  (or simply hole  200 ) that extends through the housing member  130 . The hole  200  may accommodate components of the sensor region  116 , such as the cameras  118 ,  120 , the flash  122 , the microphone  124 , and the depth sensor  126 . For example, the hole  200  may provide internal components with optical, audio, or other access to the environment surrounding the device  100  (e.g., so that cameras can capture images, a flash can illuminate scenes, a microphone can receive audio, etc.). In some cases, more, fewer, or different components may be accommodated within or proximate the hole  200 . 
       FIG.  2 A  illustrates first and second camera modules  202 ,  204 , which may include the camera lenses and sensors of the first and second cameras  118 ,  120 , respectively.  FIG.  2 A  also illustrates a depth sensor module  206 , which may include one or more sensors, emitters, and lenses of the depth sensor  126 . For example, the depth sensor module  206  may include one or more optical emitters  212  that are adapted to emit one or more beams of light, which may be used to estimate the distance. In some cases, the one or more beams of light are coherent light beams having a substantially uniform wavelength/frequency. A coherent light source may facilitate depth measurements using a time of flight, phase shift, or other optical effect. The depth sensor module  206  may also include an optical sensor  214  (as well as associated lenses) that uses time-of-flight or another optical effect to measure a distance between the device  100  and an external object. For example, the optical sensor  214  may detect the reflected light emitted from the optical emitter  212 . In some cases, the depth sensor module  206  uses a sonic output, radio output, or other type of output that may be used to measure the distance between the device  100  and one or more external objects. 
       FIG.  2 A  also illustrates a flash module  208  and a microphone module  210 . As described herein, the flash module  208  may include one or more light sources and be configured to illuminate a scene to facilitate capturing images with the cameras. The microphone module  210  may include a diaphragm, membrane, or other transducer component(s) for detecting sound. The camera modules  202 ,  204 , the depth sensor module  206 , the microphone module  210 , and the flash module  208  may all be positioned in the rear-facing sensor region  116  ( FIG.  1 B ), and may be configured to interface with the exterior environment of the device  100  through the hole  200  and the cover member  132 . 
     The device  100  may also include a bracket member  216  (also referred to herein as a camera bracket) to which the camera modules  202 ,  204  and the depth sensor module  206  may be coupled. The bracket member (or camera bracket)  216  may define a first container portion  218  configured to receive the first camera module  202 , a second container portion  220  configured to receive the second camera module  204 , and a third container portion  222  configured to receive the depth sensor module  206 . Each container portion may define openings for the optical components of the camera modules and depth sensor modules. The container portions may define flanges or side walls that at least partially surround the camera modules and the depth sensor module. The bracket member  216  may be configured to fix the relative positions of the camera modules and the depth sensor module. For example, the relative positions and/or orientations of the camera modules and the depth sensor module may be important to ensure proper operation of the features and/or functions of the camera modules and the depth sensor module. For example, in some cases it is necessary or desirable for the optical axes of the camera modules and the depth sensor module (where an optical axis may refer to a line that defines the path along which light propagates through the lenses of the modules) to be parallel or to converge at a predetermined distance away from the device  100 . As another example, it is necessary or desirable for the offset between the camera modules and the depth sensor module (e.g., the offset along the optical axes) to be set at a predetermined distance. Such alignment and positioning may be necessary or desirable to provide functions such as camera focus assistance, depth mapping, image processing, or the like, and employing a common structure (such as the bracket member  216 ) to which the camera modules and the depth sensor module are coupled may help establish and maintain the desired alignment and positioning. Notably, the bracket member  216  may establish and maintain any desired alignment, positioning, orientation, offset, or other spatial parameter, that results in the proper functioning of the optical systems. 
     The device  100  may also include a frame member  224 . The frame member  224  may be positioned in the hole  200  and attached to the housing member  130 . The frame member  224  may improve the strength, stiffness, or other physical property of the housing member  130 . For example, the frame member  224  may compensate for the reduced strength and/or stiffness of the housing member  130  resulting from the hole  200  being formed in the housing member  130 . The frame member  224  may define first, second, and third openings  226 ,  228 ,  230  for the first camera module  202 , the second camera module  204 , and the depth sensor module  206 , respectively. The frame member  224  may also define a fourth opening  232  for the flash module  208  and a fifth opening  234  for the microphone module  210 . The openings in the frame member  224  may at least partially receive the respective modules, and may provide optical, acoustic, or other access through the frame member  224 . The openings in the frame member  224  may receive other components as well. For example, a flash module trim member  238  may be positioned in or adjacent the fourth opening  232 , and may help retain the flash module  208  (as well as a flash window  236 ) in place. 
     The frame member  224  may be formed of or include steel, aluminum, magnesium, titanium, a polymer (e.g., a fiber-reinforced polymer), a composite, or any other suitable material(s). The frame member  224  may include a coating. For example, the frame member  224  may include a diamond-like carbon (DLC) coating, a metal or metallic coating, an oxide coating, or any other suitable coating (applied using plasma vapor deposition (PVD), chemical vapor deposition (CVD), electroplating, etc.). In some cases, the frame member  224  is anodized, oxidized, or otherwise processed to produce an outer shell or layer having a different composition than an underlying portion of the frame member  224 . In some cases, the exterior coatings, layers, or other treatments may provide a desired optical property, such as to impart a particular reflectance, color, or the like, to the surface of the frame member  224 . In some cases, less than all of the surfaces of the frame member  224  are coated as described above. For example, in some cases only the outward-facing surfaces include a coating. 
       FIG.  2 A  also illustrates the cover member  132 , which may overlie the frame member  224  and may define an exterior surface of the device  100 . For example, the exterior surface of the cover member  132  may be a cosmetic, exterior surface of the electronic device  100  in the area of the rear-facing sensor region  116 . The cover member  132  may be formed of sapphire, glass, polymer, ceramic, or the like. The cover member  132  may be formed of a transparent material. In other implementations, the cover member  132  may be formed of an opaque or non-transparent material. 
     In some cases, some or all of the exterior or interior surfaces of the cover member  132  may include a coating such as a paint, ink, dye, sheet, film, or the like. Such coatings may be transparent, translucent, or opaque. In some cases, the coatings are discontinuous and/or define regions along the cover member  132  having different optical properties. For example, a depth sensor window region  246  of the cover member  132  may have different optical properties (e.g., different materials, different optical properties, different layers, etc.) than an area outside and/or surrounding the depth sensor window region  246 . For example, the sensor window region  246  may be more optically transmissive (e.g., to the particular wavelength(s) of light emitted by the depth sensor and/or detected by the depth sensor) than regions surrounding the sensor window region  246 , which may be opaque. 
     The cover member  132  may define openings in which other protective elements may be positioned. For example, the cover member  132  defines a first opening  242  for the first camera module  202  and is configured to receive a first camera window  250  therein. The cover member  132  also defines a second opening  244  for the second camera module  204  and is configured to receive a second camera window  252  therein. The first and second camera windows  250 ,  252  may cover the first and second camera modules  202 ,  204 , respectively, and may protect the camera modules  204 ,  206  (and their lenses) from scratches or other damage or contaminants. The first and second openings  242 ,  244  of the cover member  132  may be configured to surround flanges or raised rims that extend around the first and second openings  226 ,  228  of the frame member  224 , and the first and second camera windows  250 ,  252  may be coupled to ledges or other features of the frame member  224  within the flanges or raised rims. Thus, in some cases, the exterior surface of the rear-facing sensor region  116  (in the area of the cameras, for example) may be defined by a portion of the cover member  132 , a top surface of a flange or raised rim of the frame member  224 , and a camera window  250 ,  252 . 
     The cover member  132  may also define a third opening  248  for the flash module  208  and a fourth opening  254  for the microphone module  210 . The flash window  236  may extend at least partially into the third opening  248  and may cover and/or protect the flash module  208  while allowing light from the flash module  208  to exit the device  100 . A microphone screen  240  may be positioned at least partially in the fourth opening  254  to cover and/or protect the microphone module  210  while allowing sound to enter into the device  100  from outside of the device  100 . 
       FIG.  2 B  illustrates an example cross-sectional view of the device  100 , viewed along line A-A in  FIG.  1 B . More particularly,  FIG.  2 B  illustrates an example arrangement of a subset of the components associated with the rear-facing sensor region  116  shown and described with respect to  FIG.  2 A . Some of the components of the device  100  may be omitted from  FIG.  2 B  for clarity. 
       FIG.  2 B  illustrates the raised rim  134  of the housing member  130 . As shown, the housing member  130  may define a fillet or curved surface extending from the back surface of the housing member  130  to the raised rim  134 . The raised rim  134  may surround and protect the side surfaces of the cover member  132 . The top surface of the raised rim  134  (which may be planar) may be substantially flush with (or proud of) the top exterior surface of the cover member  132 . 
     The frame member  224  may be attached to the housing member  130 . For example, the housing member  130  may define a first support ledge  264 , which may extend at least partially (and optionally completely) around the inner surface of the hole  200  in the housing member  130 . The frame member  224  may define a second support ledge  266  that is configured to overlap and contact the first support ledge  264 . In other cases, the frame member  224  lacks a distinct support ledge, and instead another portion of the frame member  224  rests on the first support ledge  264 . The frame member  224  may be attached to the housing member  130  by inserting the frame member  224  into the hole  200  such that the second support ledge  266  rests on the first support ledge  264  (with or without interstitial layers such as adhesives, sealants, etc.), and then securing the frame member  224  to the housing member  130 . Techniques for securing the frame member  224  to the housing member  130  are described herein with respect to  FIGS.  3 C- 3 F . The positioning of the frame member  224  relative to the housing member  130  may be defined by the position and locations of the first and second support ledges  264 ,  266 . 
     The cover member  132  may be attached to the frame member  224  to retain the cover member  132  to the device  100 . For example, the cover member  132  may be attached to the frame member  224  via an adhesive  256 . Techniques for attaching the cover member  132  to the frame member  224  are described herein with respect to  FIGS.  5 A- 5 C . 
       FIG.  2 B  also illustrates how the frame member  224 , the cover member  132 , and the camera windows (e.g., the camera window  252 ) may be arranged. For example, the frame member  224  may define a raised rim  258 , which may extend through an opening (e.g., the opening  244 ) in the cover member  132 . The frame member  224  may also define a ledge within the raised rim  258  that supports the camera window  252 . When assembled, the cover member  132 , the top surface of the raised rim  258 , and the camera window  252  may be substantially flush. In some cases, the raised rim  258  may be omitted, and the camera window  252  may be secured to the cover member  132  within the opening  244  (e.g., the camera window  252  may abut or be attached to the cover member  132  within the opening  244 ). In other cases, the cover member  132  may not have an opening for a separate camera window, but instead may include a transparent region above the camera. 
       FIG.  2 B  also illustrates example configurations of the second camera module  204  and the depth sensor module  206 , as well as the arrangement of the bracket member  216  relative to the frame member  224 . For example, the container portions of the bracket member  216  may be positioned in recesses, cavities, or other regions (defined by a network of ribs or flanges) of the frame member  224 . As shown, the second camera module  204  is positioned in the second container portion  220 , and is aligned with an opening  260  in the bracket member  216 , the second opening  228  in the frame member, and the second opening  244  in the cover member  132  (and the camera window  252 ). Similarly, the depth sensor module  206  is positioned in the third container portion  222 , and is aligned with an opening  262  in the bracket member  216 , the third opening  230  in the frame member, and the depth sensor window region  246  of the cover member  132 . As noted above, the depth sensor window region  246  may be a portion of the cover member  132  that has a different coating than another portion of the cover member  132  (or otherwise has optical properties that allow the depth sensor module  206  to transmit and/or receive light through the cover member  132 ). 
       FIGS.  3 A- 3 B  illustrate a portion of the housing  104  with the frame member  224  installed. (Other components are omitted from  FIGS.  3 A- 3 B .) As noted above, the frame member  224  may provide structural support to the housing of the device  100 . For example, the hole  200  in the housing  104  may reduce the strength, stiffness, and/or overall structural soundness of the housing  104  in the area of the hole  200 . Further, the area of the housing  104  where the hole  200  is positioned is proximate an area where a joint structure mechanically joins the housing member  130  with the housing member  128 , which may be weaker than areas that are defined by uninterrupted metal materials. 
     These effects may be mitigated, however, by attaching the frame member  224  to the housing  104  in the hole  200 . Further, the configuration of the frame member  224  may help direct forces from impacts, drop events, or the like. For example, the frame member  224  may define ribs  300  (indicated by the stippling pattern). The ribs  300  may define recesses or cavities along the back side (e.g., the interior-facing side) of the frame member  224 . Components may be positioned in the recesses or cavities defined by the ribs  300 , such as portions of the bracket member  216 , camera modules, and the like. The ribs  300  may define load paths from the peripheral sides of the frame member  224  (e.g., the sides along the top and side of the device  100 ) to the main, central structural portion of the housing member  130 . More broadly, the ribs  300  may help improve the stiffness and/or strength of the housing  104  in the area of the hole  200 , as compared to a frame member  224  without ribs, or a housing that omits the frame member  224 . 
       FIG.  3 B  illustrates how the ribs  300 , and the frame member  224  more generally, improve the strength of the device  100  and/or its resistance to deformation or damage in the event of an impact. More particularly,  FIG.  3 B  shows the device  100  at the moment of impact with a surface  304  (e.g., the ground). As shown, forces from the impact are transferred or directed from the point of impact (e.g., the corner of the device  100 ) through the ribs  300 , and to the main body of the housing member  130 . Load path  302  illustrates one example load path extending from the side of the housing  104  through the frame member  224  (though this is merely representative and is not intended to show the only load path). Stated another way, the ribs  300  provide a structural support to the housing member  130  in the area of the hole  200  to help prevent the housing member  130  from collapsing, bending, deforming, or otherwise being damaged due to impacts. 
     In order for the frame member  224  to provide structural support to the housing  104 , the frame member  224  may be securely attached to the housing. For example, the frame member  224  may be secured to the housing via welding, adhesives, fasteners, mechanical interlocks, or any other suitable technique.  FIG.  3 C  illustrates a portion of the housing  104  with the frame member  224  installed, showing example techniques for securely attaching the frame member  224  to the housing  104 . As shown in  FIG.  3 C , the frame member  224  may be attached to the housing  104  via welds and fasteners. For example, the frame member  224  may be welded (or soldered, brazed, or the like) to the housing member  130  at attachment locations  306 ,  308 ,  310 , and  312  (among other possible locations). The frame member  224  may also be attached to the housing member  130  via fasteners  314 ,  316 , and  318 . The fasteners may be threaded fasteners, rivets, or any other suitable fastener. 
       FIG.  3 D  is a partial cross-sectional view of the device  100 , viewed along line B-B in  FIG.  3 C , showing how a fastener may secure the frame member  224  to the housing member  130 . The fastener  314  may extend through a hole (e.g., a through-hole) in the housing member  130 , and into a hole (e.g., a threaded hole) in the frame member  224 . The fastener  314  may define a chamfered or angled surface  320  that is configured to contact the housing member  130  at the time of installation (and remain in contact with the housing member  130 ). By initiating contact between the chamfered surface  320  of the fastener  314  and the housing member  130  upon assembly, a load applied to the housing  104  (e.g., from a drop event) may be transferred through the fastener  314  immediately upon impact. By contrast, a conventional screw or bolt (e.g., with a cylindrical shaft portion) may result in a clearance or gap between the through hole in the housing member  130  and the screw or bolt. Upon an impact, the presence of the clearance or gap may allow the frame member  224  to shift relative to the housing member  130 , thereby straining other connections between the frame member  224  and the housing (such as the weld joints) and otherwise reducing the structural integrity of the device. 
       FIG.  3 E  is a partial cross-sectional view of the device  100 , viewed along line C-C in  FIG.  3 C , showing how a weldment may be used to secure the frame member  224  to the housing member  130 . In particular, the frame member  224  may be positioned proximate the housing member  130  and an optional weld bracket  322 . The frame member  224  may be fastened to the weld bracket  322  via a weld bead  324 . The weld bracket  322  may be attached to the frame member  224  via any suitable technique, such as welding, brazing, fusion bonding, soldering, adhesives, rivets, or the like. In some cases, the weld bracket  322  is part of the housing member  130 , rather than being a separate component as shown in  FIG.  3 E  (e.g., the weld bracket  322  and the housing member  130  may be part of a single unitary structure). While  FIG.  3 E  illustrates a weld along a butt joint between the frame member  224  and the housing member  130 , welds may also be applied to or used with other types of joints, such as lap joints, interlocks, or the like. 
       FIG.  3 F  illustrates an attachment technique that may be used with an alternative frame member configuration.  FIG.  3 F  is a partial cross-sectional view of a device, viewed along a line similar to line C-C in  FIG.  3 E . As shown in  FIG.  3 F , a frame member  326  may define a front flange  328  that is configured to engage an exterior surface of the housing member  334 . The frame member  326  and the housing member  334  may be similar in other respects to the frame member  224  and the housing member  130 , and for brevity details of those components will not be repeated here. The frame member  326  may also define an angled surface  330  that is configured to overlap at least a portion of the housing member  334 . A wedge component  332  may be positioned between the angled surface  330  and the housing member  334 . The wedge component  332  may force the frame member  326  upwards (relative to the orientation shown in  FIG.  3 F ), thereby producing an engagement force between the front flange  328  and the exterior surface of the housing member  334  and tending to rigidly retain the frame member  326  to the housing member  334 . The angle of the angled surface  330  and the wedge member  332  (as well as the materials and/or surface textures of the angled surface  330  and the wedge member  332 ) may be selected to produce a self-locking interface, in which downward forces applied to the frame member  326  (relative to the orientation shown in  FIG.  3 F ) do not cause the wedge member  332  to be forced out of position (e.g., to the right as depicted in  FIG.  3 F ). In some cases, the wedge member  332  is secured to the frame member  326  and/or the housing member  334 , such as via welding, soldering, brazing, fasteners, adhesives, mechanical interlocks, or the like. 
       FIGS.  4 A- 4 C  illustrate details of the bracket member  216  and its integration with the device  100 .  FIG.  4 A , for example, depicts a perspective view of the bracket member  216 . As described above, the bracket member  216  defines container portions  218 ,  220 ,  222  configured to receive the first and second camera modules  202 ,  204 , and the depth sensor module  206 . The bracket member  216  may also define openings  402 ,  404 ,  406  to allow the camera modules and the depth sensor module access to the external environment through the bracket member  216 . The bracket member  216  may also define a sensor opening  400 , which may be aligned with a sensor (e.g., the sensor  110 ). More particularly, the bracket member  216  may be positioned between the sensor  110  and the display of the device  100 , and as such is in a position that may otherwise interfere with the sensing function of the sensor  110 . The sensor opening  400  may allow the sensor  110  to sense objects that are proximate the display  103  and cover  102  of the device  100 . For example, the sensor opening  400  may allow magnetic fields from a magnet of a cover accessory to reach the sensor  110  and allow the sensor  110  to detect the presence and/or absence of the magnetic field. 
       FIG.  4 B  is a partial exploded view of the device  100 , showing the bracket member  216  removed decoupled from the device  100 . As shown in  FIG.  4 B , the device  100  may include a circuit board  408 , on which the sensor  110  may be positioned. The portion of the circuit board  408  with the sensor  110  may extend under the bracket member  216  such that the sensor  110  is positioned under the opening  400 . 
       FIG.  4 B  also illustrates how the container portions of the bracket member  216  may nest in the corresponding container portions defined by the ribs  300  of the frame member  224 , and also shows the first and second camera modules  202 ,  204  and the depth sensor module  206  above their respective container portions of the bracket member  216 . As shown, the first and second camera modules  202 ,  204  and the depth sensor module  206  may be coupled to one or more circuit elements  412  (e.g., flexible circuit boards), which may include connectors that attach to the circuit board  408 . A switch module  410  may also include a circuit element (e.g., a flexible circuit board) that extends over or integrates with the circuit elements of the first and second camera modules  202 ,  204  and the depth sensor module  206  and electrically couples to the circuit board  408 . 
       FIG.  4 C  shows a portion of the device  100  with the bracket member  216  installed in the device. The first and second camera modules  202 ,  204  and the depth sensor module  206  are omitted for clarity. 
     As described above, the cover member  132  may be attached to the device  100  by adhering the cover member  132  to the frame member  224 .  FIGS.  5 A- 5 B  illustrate an example process by which the cover member  132  may be attached to the frame member  224 . In particular, the adhesive  256  may be deposited on a bottom surface of the cover member  132  (and/or onto a top surface of the frame member  224 ), and the cover member  132  may be pressed into the hole  200  and onto the top surface of the frame member  224  using a press  500 . The press  500  may be heated, and may be used to heat the adhesive  256  before, during, and/or after the process of pressing the cover member  132  onto the frame member  224 . For example, the adhesive  256  may be a heat activated adhesive, and the heat from the press  500  may cause the adhesive  256  to adhere to the cover member  132  and the frame member  224 . 
     The press  500  may be configured to position the cover member  132  in the hole  200  so that the exterior surface of the cover member  132  is flush (e.g., to within 25 microns) with the top surface of the raised rim  134 . For example, when the press  500  is moved downward (indicated by the arrows  504 ) and the cover member  132  is positioned in the hole  200 , a bottom surface  502  of the press  500  (which is essentially flush with the exterior surface of the cover member  132 ) comes into contact with and is travel-limited by the top surface of the raised rim  134 , as shown in  FIG.  5 B . At this point, the exterior surface of the cover member  132  is flush with the top surface of the raised rim  134 . The adhesive  256  may be allowed to cure to retain the cover member  132  in this position. 
     Due to manufacturing and material variabilities, the distance between the top surface of the frame member  224  and the top surface of the raised rim  134  may vary between different devices. Accordingly, the structure of the device  100  and the process described with respect to  FIGS.  5 A- 5 C  are configured to accommodate such dimensional differences while still consistently producing devices in which the cover member  132  is flush with the raised rim  134 . This may be accomplished, for example, by providing a sufficient amount of adhesive  256  to accommodate different sized gaps between the top of the frame member  224  and the bottom of the cover member  132  (when the top of the cover member  132  is flush with the raised rim  134 ).  FIG.  5 A  illustrates the adhesive  256  having a thickness  506 . When the cover member  132  is positioned in place by the press  500 , as shown in  FIG.  5 B , the adhesive  256  is compressed somewhat (e.g., to thickness  508 , matching the gap between the cover member  132  and the frame member  224 ), ensuring that the adhesive  256  makes intimate contact with the surface of the frame member  224 . This process also results in the adhesive  256  flowing or expanding laterally a certain amount, as defined by the amount of the adhesive  256  and the actual gap between the components. 
     In cases where the gap between the cover member  132  and the frame member  224  is greater than or less than that shown in  FIG.  5 B , the adhesive  256  may flow laterally by different amounts in order to accommodate the different gap sizes.  FIG.  5 C , for example, shows an example in which the housing  130 , frame member  224 , and cover member  132  result in a gap size of  510  (larger than the gap in  FIG.  5 B ). Due to the ability of the adhesive  256  to flow laterally, along with the initial height  506  of the adhesive  256  being greater than the gap size  510 , the adhesive  256  can successfully secure the cover member  132  to the frame member  224  despite the different gap size and while still positioning the cover member  132  so that the exterior surface of the cover member  132  is flush with the top surface of the raised rim  134 . In cases where the gap size is smaller than that shown in  FIG.  5 B , the adhesive  256  may flow laterally more than shown in  FIG.  5 B . Furthermore, other types of irregularities may also be accommodated using this assembly technique. For example, variations in a flatness of the cover member  132 , the frame member  224 , the ledges of the frame member  224 , and/or the ledges of the housing member  130  may result in a non-uniform gap size between the cover member  132  and the frame member  224 . The ability of the adhesive to flow (as well as the attachment process using the raised rim  134  as a datum for the positioning of the cover member  132 ) allows the non-uniform gap sizes to be accommodated while maintaining the flushness of the cover member  132  and the raised rim  134 . 
     The height  506  of the adhesive  256  may be selected to accommodate a range of potential gap sizes. For example, the height  506  may be about 100 microns, about 150 microns, about 200 microns, about 250 microns, or any other suitable height. In some cases, the particular height of adhesive may be selected based on one or more measurements of the components of the device  100 . For example, before application of the adhesive  256  to the cover member  132 , components such as the cover member  132 , the frame member  224 , and/or the housing member  130  may be measured (either in an unassembled or partially assembled state). Based on the measurement, if a gap between the cover member  132  and the frame member  224  is measured or estimated to be greater than a threshold value, a first thickness of adhesive is applied (e.g., about 200 microns), and if it is measured or estimated to be less than a threshold value, a second thickness of adhesive is applied (e.g., about 150 microns). Other thicknesses are also contemplated. 
     While  FIGS.  5 A- 5 C  illustrate adhesive around the perimeter of the bottom surface of the cover member  132 , this is merely one configuration or positioning of the adhesive. For example, in some cases the adhesive  256  may be deposited in a web-like or other pattern more complex than simply a single path around an outer perimeter. For example,  FIG.  7 A  illustrates an adhesive application pattern that may be used to secure the cover member  132  to the frame member  224 . 
     In compact electronic devices, such as tablet computers, the close proximity of various electrical components may require shielding and other techniques to mitigate or eliminate the effects of electrical noise or other interference on various systems. A depth sensor module  206 , for example, may include a high-frequency oscillator that may produce electromagnetic noise that may interfere with other electronics or circuits of the device  100 . Accordingly, the depth sensor module  206  may be shielded and/or grounded to help reduce or mitigate the negative effects of the noise. 
       FIGS.  6 A- 6 C  illustrate an example technique for effectively shielding and grounding the depth sensor module  206 .  FIG.  6 A , for example, illustrates a partial view of the device  100 , showing the housing with the frame member  224  installed in the housing member  130 . The device  100  may include a conductive cowling  600  coupled to the frame member  224 . The cowling  600  is formed from a conductive material, such as a copper, gold, or other flexible metal foil or film. The cowling  600  defines an opening that is aligned with or otherwise coincides with the opening  230  in the frame member  224  and which is configured to allow the depth sensor module  206  access to the exterior environment. The cowling  600  may be configured to contact and conductively couple to a housing of the depth sensor module  206  as well as to the frame member  224  (which may be conductively coupled to a ground plane of the device  100 ). Thus, the cowling  600  defines a conductive path from the depth sensor module  206  to an electrical ground, thereby helping prevent interference from the depth sensor module  206  from affecting other circuits or components of the device  100 . 
     As shown with respect to  FIGS.  6 B- 6 C , when the depth sensor module  206  is coupled to the device  100 , it may be forced against the cowling  600  such that the cowling  600  deforms. The cowling  600  may define a series of conductive tabs  601  separated from one another by spaces  602 . The tabs  601  may facilitate the cowling  600  deforming to conform against the depth sensor module  206  as the depth sensor module  206  is installed, while helping prevent and/or avoid buckling, curling, or other unwanted deformations that may distort the cowling  600  in a manner that may be detrimental to the function of the cowling  600 . 
       FIG.  6 B  is a partial cross-sectional view of the device  100 , viewed along line D-D in  FIG.  6 A , showing the depth sensor module  206  prior to installation in the device  100 .  FIG.  6 B  shows the cowling  600  attached to the frame member  224  along a surface around the opening  230  in the frame member  224 . The cowling  600  may be conductively coupled to the frame member  224  in this area via conductive adhesive, brazing, soldering, or any other technique that retains the cowling  600  to the frame member  224  and facilitates a conductive coupling between these components. A foam  603  (or other compliant material) may be positioned between the cowling  600  and the cover member  132  (e.g., below the tabs  601  that extend over and/or into the opening). The foam  603  may be configured to deform when the depth sensor module  206  is put into position in the device and to provide a biasing force between the tabs  601  and the depth sensor module  206  (e.g., to bias the tabs  601  against the depth sensor module  206 , thereby maintaining a physical and conductive coupling between the tabs  601  and the depth sensor module  206 ). 
       FIG.  6 C  is a partial cross-sectional view of the device  100 , viewed along line D-D in  FIG.  6 A , showing the depth sensor module  206  after installation in the device  100 . As shown, the cowling  600  has deformed (e.g., the tabs  601  of the cowling  600 ), as has the foam  603 . The tabs  601  have conformed to the contour of the depth sensor module  206 , and the foam  603  helps define the contour and maintain the tabs  601  in conformance and contact with the depth sensor module  206 . 
       FIG.  6 D  is a perspective view of the depth sensor module  206 , showing additional components that may be used to shield the depth sensor module  206 . In particular, a flexible conductive material  614  (e.g., a copper tape) may be wrapped around at least a portion of the depth sensor module  206 , such as around at least two sides of the depth sensor module  206 . The conductive material  614  may also extend over a top of the depth sensor module  206  and along the top surface of a flexible circuit element  612  that interconnects the depth sensor module  206  with other circuit elements of the device (e.g., via a connector  616 ). The conductive material  614  may be conductively coupled to a ground plane of the device  100  to facilitate the shielding function of the conductive material  614 . 
     As noted above, the cover member  132  may be attached to the frame member  224  using an adhesive  256 . The adhesive  256  may be arranged in a pattern that provides a large surface area for the adhesive  256  to bond to, both on the cover member  132  and the frame member  224 .  FIG.  7 A  illustrates a portion of the device  100  that includes the rear-facing sensor region  116 , illustrating an example application pattern for the adhesive  256 . As shown, the adhesive  256  at least partially surrounds the various components of the rear-facing sensor region  116 . For example, the adhesive  256  extends around the first camera  118 , the second camera  120 , the flash  122 , the depth sensor  126 , and the microphone  124 . By depositing the adhesive  256  in this way, the cover member  132  may be securely attached to the device  100 . 
     The adhesive  256  may perform other functions in addition to securing the cover member  132  to the frame member  224 . For example, the adhesive  256  may surround the microphone  124  (or an area associated with the microphone  124 ) to help define a sealed audio path extending from the exterior environment to the microphone module within the device  100 .  FIG.  7 B  illustrates a detail view of the rear-facing sensor region  116  corresponding to area E-E in  FIG.  7 A .  FIG.  7 B  illustrates the pattern of the adhesive  256  around the microphone region.  FIG.  7 B  also shows a boundary of a recess  700  that is formed in the frame member  224  and that forms part of the acoustic path leading from the opening  254  in the cover member  132  to the opening  234  in the frame member  224 . Notably, the opening  254  is offset from (e.g., is not coaxial with) the opening  234 . Accordingly, as described with respect to  FIG.  7 C , the acoustic path from the exterior environment to the microphone module  210  may be non-linear and may pass through a chamber or volume defined between the cover member  132  and the frame member  224  (with the path including the recess  700  of the frame member  224 ).  FIG.  7 B  also illustrates the outer boundary of the microphone screen  240  that may cover the opening  254  in the cover member  132 . 
       FIG.  7 C  is a partial cross-sectional view of the device  100 , viewed along line F-F in  FIG.  7 B . As shown, an acoustic path  706  is defined from the exterior of the device  100  to the diaphragm  712  (or other sensing element) of the microphone module  210  (which may be positioned in a recess  708  defined by the frame member  224 ). The acoustic path  706  extends through a volume  704  defined in part by the recess  700  and the cover member  132 . The acoustic path  706  also extends through the microphone screen  240 , which may be positioned in the opening  254  of the cover member  132 . The microphone screen  240  may be attached to the cover member  132  with an adhesive  702 , and may define a deformed portion that extends into the opening  254  and defines an exterior portion that is flush with the exterior surface of the cover member  132  (though in some embodiments it may be recessed or proud relative to the exterior surface of the cover member  132 ). 
     The volume through which the acoustic path  706  extends may be a sealed or enclosed volume, with the exception of the opening  254  in the cover member  132 . For example, the adhesive  256  that attaches the cover member  132  to the frame member  224  may extend around the perimeter of the recess  700 , as shown in  FIG.  7 B , thereby enclosing and/or sealing the volume  704  from other environments (e.g., the exterior environment and the internal volume of the device  100 ). Similarly, the microphone module  210  may be attached to the frame member  224  via an adhesive  710  (e.g., a pressure-sensitive adhesive), which may extend around the opening  234  in the frame member  224  to enclose and/or seal the joint between the microphone module  210  and the frame member  224 . By sealing the volume through which the acoustic path  706  extends, interference from both internal and external sources of audible interference may be avoided. In some cases, the sealing provided by the adhesives  256  and  710  is a watertight seal and/or a hermetic seal. 
     As noted above, the frame member  224  may include a coating, such as a DLC coating, along at least the outward-facing surfaces of the frame member  224  (e.g., the top surfaces as depicted in  FIG.  7 C ). In some cases, the surface of the recess  700  lacks the coating. For example, a coating such as a DLC coating may be applied to the frame member  224  after the recess  700  is formed in the frame member  224  (e.g., by machining). The DLC coating may then be locally removed from areas of the frame member  224 , such as from the surface of the recess  700 , areas where adhesive is applied to the frame member  224 , or the like. 
       FIG.  8 A  is a top view of an example optical sensor assembly  800  that may be used for the depth sensor  126 . The sensor assembly  800  may include an optical sensor  802  (e.g., a charge coupled device (CCD) sensor, a complementary metal oxide semiconductor (CMOS) sensor, or any other suitable type of sensor. The optical sensor  802  may be attached to a substrate  804 , and may be conductively coupled (through the substrate  804 ) to one or more connection pads, such as connection pad  806 . The sensor assembly  800  may also include a flexible circuit board  808 , which may include connection pads that conductively couple to the connection pads on the substrate  804 , as well as conductive traces that facilitate conductive coupling between the sensor  802  and other components. 
       FIG.  8 B  is a partial cross-sectional view of the optical sensor assembly  800 , viewed along line G-G in  FIG.  8 A . The flexible circuit board  808  may include a flexible substrate  814  (which may include one or more sub-layers, such as one or more polyimide sheets, adhesive layers, and the like). The flexible circuit board  808  may also include connection pads  810  that are exposed along the top surface of the flexible circuit board  808  and are configured to be conductively coupled to the connection pads (e.g., the connection pad  806 ) of the substrate  804 . The flexible circuit board  808  may also include components  816  (e.g., electrical traces, connection pads, circuit elements, or other components) that are coupled to a surface of the flexible circuit board  808  but are not intended to be conductively coupled to the substrate  804 . Accordingly, such components  816  may be covered by a coverlay  818 , which may protect and electrically insulate the components  816 . 
     The flexible circuit board  808  may be coupled to the substrate  804  using a conductive adhesive  807 , such as an anisotropic conductive film. The conductive adhesive  807  may both bond the flexible circuit board  808  to the substrate  804 , and also conductively couple the connection pads  806  to the connection pads  810 . 
     In some cases, the coverlay  818  on the top surface of the flexible circuit board  808  may cause the flexible circuit board  808  to bend or deform when the flexible circuit board  808  is coupled to the substrate  804 .  FIG.  8 B  illustrates such a condition, where the flexible circuit board  808  has deformed in the areas around the coverlay  818  to accommodate the extra thickness of the coverlay  818  on the top surface. This configuration may strain the flexible circuit board  808  as well as the adhesive joints between the connection pads  806  and the connection pads  810 . 
       FIGS.  8 C- 8 D  are partial cross-sectional views the optical sensor assembly  800  using a different flexible circuit board configuration. In particular, instead of mounting components  816  on the top exterior surface of a flexible substrate  814 , and then applying a coverlay  818  over the components  816  (which adds additional height to the flexible circuit board in the area of the coverlay),  FIGS.  8 C- 8 D  show a flexible circuit board  820  in which components  832  are sandwiched between multiple substrate layers of the flexible circuit board  820 . 
       FIG.  8 C  shows the flexible circuit board  820  prior to being attached to the substrate  804 . As shown, the flexible circuit board  820  includes components  832  (e.g., electrical traces, connection pads, circuit elements, or other components) between a first substrate layer  831  and a second substrate layer  833 . The first and second substrate layers may be polyimide layers that are adhered together after positioning the components  832  therebetween. Connection pads  822  may be exposed on a top surface of the flexible circuit board  820  so they can be conductively coupled to the connection pads  806  on the substrate  804 . The flexible circuit board  820  may also include vias  830  to conductively couple the external connection pads  822  to other traces, circuit elements, or other components that are between the first and second substrate layers  831 ,  833 , or on the bottom surface of the flexible circuit board  820 . The flexible circuit board  820  may also include components  826  (e.g., electrical traces, connection pads, circuit elements, or other components) on the bottom surface of the flexible circuit board  820 , portions of which may be covered by a coverlay  828  (e.g., to protect and/or electrically insulate the components  826 ). 
     The configuration of the flexible circuit board  820  results in a top side that is significantly flatter than the flexible circuit board  808  in  FIG.  8 B . In particular, by using multiple laminations and positioning components between the laminations (instead of on top of the flexible substrates), the need for an exterior coverlay on the top surface can be eliminated.  FIG.  8 D  illustrates the optical sensor assembly  800  with the flexible circuit board  820  attached. As shown, the conductive adhesive  807  bonds the flexible circuit board  820  to the substrate  804 , and also conductively couples the connection pads  822  to the connection pads  810 . Unlike the flexible circuit board  808  in  FIG.  8 B , however, the flexible circuit board  820  does not significantly deform, flex, or bend when attached to the substrate  804 . Rather, the flexible circuit board  820  remains substantially flat and/or undeformed, thereby resulting in a less strained flexible circuit board  820  and reducing the likelihood of delamination, breaking, or other potential damage. 
       FIG.  9    depicts an example schematic diagram of an electronic device  900 . The electronic device  900  may be an embodiment of or otherwise represent the device  100  (or any other device(s) described herein). The device  900  includes one or more processing units  901  that are configured to access a memory  902  having instructions stored thereon. The instructions or computer programs may be configured to perform one or more of the operations or functions described with respect to the electronic devices described herein. For example, the instructions may be configured to control or coordinate the operation of one or more displays  908 , one or more touch sensors  903 , one or more force sensors  905 , one or more communication channels  904 , one or more audio input systems  909 , one or more audio output systems  910 , one or more positioning systems  911 , one or more sensors  912 , and/or one or more haptic feedback devices  906 . 
     The processing units  901  of  FIG.  9    may be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processing units  901  may include one or more of: a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), or combinations of such devices. As described herein, the term “processor” is meant to encompass a single processor or processing unit, multiple processors, multiple processing units, or other suitably configured computing element or elements. The processing units  901  may be coupled to a circuit board, such as the circuit board  408  ( FIG.  4 B ), or a different circuit board. 
     The memory  902  can store electronic data that can be used by the device  900 . For example, a memory can store electrical data or content such as, for example, audio and video files, images, documents and applications, device settings and user preferences, programs, instructions, timing and control signals or data for the various modules, data structures or databases, and so on. The memory  902  can be configured as any type of memory. By way of example only, the memory can be implemented as random access memory, read-only memory, Flash memory, removable memory, or other types of storage elements, or combinations of such devices. 
     The touch sensors  903  may detect various types of touch-based inputs and generate signals or data that are able to be accessed using processor instructions. The touch sensors  903  may use any suitable components and may rely on any suitable phenomena to detect physical inputs. For example, the touch sensors  903  may be capacitive touch sensors, resistive touch sensors, acoustic wave sensors, or the like. The touch sensors  903  may include any suitable components for detecting touch-based inputs and generating signals or data that are able to be accessed using processor instructions, including electrodes (e.g., electrode layers), physical components (e.g., substrates, spacing layers, structural supports, compressible elements, etc.) processors, circuitry, firmware, and the like. The touch sensors  903  may be integrated with or otherwise configured to detect touch inputs applied to any portion of the device  900 . For example, the touch sensors  903  may be configured to detect touch inputs applied to any portion of the device  900  that includes a display (and may be integrated with a display). The touch sensors  903  may operate in conjunction with the force sensors  905  to generate signals or data in response to touch inputs. A touch sensor or force sensor that is positioned over a display surface or otherwise integrated with a display may be referred to herein as a touch-sensitive display, force-sensitive display, or touchscreen. 
     The force sensors  905  may detect various types of force-based inputs and generate signals or data that are able to be accessed using processor instructions. The force sensors  905  may use any suitable components and may rely on any suitable phenomena to detect physical inputs. For example, the force sensors  905  may be strain-based sensors, piezoelectric-based sensors, piezoresistive-based sensors, capacitive sensors, resistive sensors, or the like. The force sensors  905  may include any suitable components for detecting force-based inputs and generating signals or data that are able to be accessed using processor instructions, including electrodes (e.g., electrode layers), physical components (e.g., substrates, spacing layers, structural supports, compressible elements, etc.) processors, circuitry, firmware, and the like. The force sensors  905  may be used in conjunction with various input mechanisms to detect various types of inputs. For example, the force sensors  905  may be used to detect presses or other force inputs that satisfy a force threshold (which may represent a more forceful input than is typical for a standard “touch” input) Like the touch sensors  903 , the force sensors  905  may be integrated with or otherwise configured to detect force inputs applied to any portion of the device  900 . For example, the force sensors  905  may be configured to detect force inputs applied to any portion of the device  900  that includes a display (and may be integrated with a display). The force sensors  905  may operate in conjunction with the touch sensors  903  to generate signals or data in response to touch- and/or force-based inputs. 
     The device  900  may also include one or more haptic devices  906 . The haptic device  906  may include one or more of a variety of haptic technologies such as, but not necessarily limited to, rotational haptic devices, linear actuators, piezoelectric devices, vibration elements, and so on. In general, the haptic device  906  may be configured to provide punctuated and distinct feedback to a user of the device. More particularly, the haptic device  906  may be adapted to produce a knock or tap sensation and/or a vibration sensation. Such haptic outputs may be provided in response to detection of touch and/or force inputs, and may be imparted to a user through the exterior surface of the device  900  (e.g., via a glass or other surface that acts as a touch- and/or force-sensitive display or surface). 
     The one or more communication channels  904  may include one or more wireless interface(s) that are adapted to provide communication between the processing unit(s)  901  and an external device. The one or more communication channels  904  may include antennas (e.g., antennas that include or use the housing members of the housing  104  as radiating members), communications circuitry, firmware, software, or any other components or systems that facilitate wireless communications with other devices. In general, the one or more communication channels  904  may be configured to transmit and receive data and/or signals that may be interpreted by instructions executed on the processing units  901 . In some cases, the external device is part of an external communication network that is configured to exchange data with wireless devices. Generally, the wireless interface may communicate via, without limitation, radio frequency, optical, acoustic, and/or magnetic signals and may be configured to operate over a wireless interface or protocol. Example wireless interfaces include radio frequency cellular interfaces (e.g., 2G, 3G, 4G, 4G, 4G long-term evolution (LTE), 5G, GSM, CDMA, or the like), fiber optic interfaces, acoustic interfaces, Bluetooth interfaces, infrared interfaces, USB interfaces, Wi-Fi interfaces, TCP/IP interfaces, network communications interfaces, or any conventional communication interfaces.
