Abstract: In some examples, a corner shield is provided for protecting a surface-mount device (SMD) on a printed circuit board (PCB). An example corner shield comprises a rigid structure configured to conform to a corner area of the SMD, and one or more mounting surfaces configured to mount the rigid structure to one or more soldering pads on the PCB adjacent to the SMD.

Abstract: An electronic device includes a housing defining an internal volume, a front opening, and a rear opening. The electronic device can include a display component disposed at the front opening and a rear cover disposed at the rear opening. A logic board can be disposed in the internal volume. The device can also include a thin film thermopile including a cold junction bonded to the logic board and a hot junction bonded to the rear cover.
