    Abstract: An electronic device may have housing structures, electrical components, and other electronic device structures. Stress sensing structures may be formed using coatings on these electronic device structures. Stress sensing structures may have strip-shaped links that extend between pads or may be formed from blanket films. A stress sensing coating may be formed from a transparent thin film. The transparent thin film may be illuminated with monochromatic light while a video camera captures video images of resulting optical interference patterns. The video images may be captured during a test in which a device structure is exposed to stress from an impact between the device and an external object. Stress sensing coatings may also be formed from layers of material that develop cracks upon exposure to stress. Stress sensing structures may be used to evaluate stress during tests and to monitor stress during normal device use.

    Abstract: This application relates to various button related embodiments for use with a portable electronic device. In some embodiments, a snap clip can be integrated with a button bracket to save space where two separate brackets would take up too much space in the portable electronic device. In other embodiments, a tactile switch can be waterproofed by welding a polymeric layer atop a tactile switch assembly. In this way water can be prevented from contacting moisture sensitive components of the tactile switch assembly. The weld joining the polymeric layer to the tactile switch can include at least one gap to trapped gas surrounding the tactile switch assembly to enter and exit during heat excursions caused by various operating and/or assembly operations.

    Abstract: Systems and methods for forming button assemblies for electronic devices are disclosed. According to some embodiments, the button assemblies include one or more sound improvement features to improve the sound that the button assemblies make when pressed by users of the electronic devices. According to some embodiments, the button assemblies include shims that provide proper alignment of the various components of the button assemblies and to accommodate any tolerance stack up of the various components of the button assemblies. The shims can include alignment features to prevent the shims from shifting within the button assemblies. According to some embodiments, thicknesses of the shims are customized to accommodate varying tolerance stack ups of the components of the button assemblies. In some embodiments, the button assemblies include a combination of sound improvement features and shims.

    Abstract: An electronic device may contain electrical components mounted on one or more substrates such as printed circuit boards. During a drop event, the printed circuit boards and components may be subjected to stresses. Strain gauges may be formed from metal traces embedded within dielectric layers in the printed circuit boards. The strain gauges may be used to make stress measurements at various locations on the boards. Stress data may be collected in response to data from an accelerometer indicating that the device has been dropped. Stress data collection may be halted in response to determining that the device has struck an external surface. Impact may be detected using accelerometer data, strain gauge output, or other sensor data. Stress data may be analyzed by the electronic device or external equipment.
