Abstract: The structural rigidity of a device is improved by overmolding one or more layers of the device housing over the antenna components, improving overall wall thickness and avoiding air gaps present in conventional devices. Pull tabs are implemented for battery installation and removal using a stretch-release adhesive connected to the tabs that can hold the battery in place and, upon pulling of the pull tabs, cause the battery to be removable from the device. Camera sensors larger than the camera optics are usable in a device by utilizing only image data captured by those pixels of the sensor that correspond to the appropriate part of the camera optics. Mechanical interlocks can be used advantageously for alignment and connection strength for side soldering. Optical alignment processes are used advantageously in situations such as mounting a device camera relative to an opening of a light absorbing layer on a cover glass sheet.
