A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.

Corrosion mitigation for an external connector of an electronic device

Electronic devices may contain electrical systems in which electrical components are mounted on a substrate such as a printed circuit board. The electrical components may include surface mount technology components. Multiple surface mount technology components may be stacked on top of each other and beside each other to form an electrical component that minimizes the amount of area that is consumed on a printed circuit board. Noise suppression circuits and other circuits may be implemented using stacked surface mount technology components. Surface mount technology components placed on the printed circuit board may be pushed together and subsequently injection molded to form packed component groups. An integrated circuit may be mounted to the printed circuit board via an interposer and may cover components mounted to the printed circuit board. An integrated circuit may be mounted over a recessed portion of the printed circuit board on which components are mounted.

Printed circuit board with compact groups of devices

The disclosed embodiments relate to techniques for facilitating thermal transfer in a portable electronic device. This portable electronic device may include a battery pack, which includes a battery cell and enclosure material for enclosing the battery cell. This enclosure material extends beyond the enclosure for the battery cell to facilitate thermal transfer within the portable electronic device.
