Electronic device subassemblies

摘要

An electronic device may include subassemblies such as battery structures, electromagnetic shielding structures, and button structures. The electromagnetic shielding structures may include a conductive fence and a flexible shielding layer that covers electronic components. The electromagnetic shielding structure may be formed with a recess that receives a protruding portion of a battery. The recess may be formed from a multi-level shielding structure that includes rigid and flexible portions. The button structures may be mounted to a ledge that is formed as an integral part of a device housing. An electronic device battery may be enclosed in a protective battery sleeve. The battery sleeve may include a center portion that encloses the battery and peripheral portions that are folded and coupled to the center portion by adhesive material interposed between opposing surfaces of the folded peripheral portions and the center portion of the battery sleeve.

主权项

1. A printed circuit board, comprising:
a substrate; an electronic component mounted to the substrate, wherein the electronic component has a first height; a conductive fence surrounding the electronic component on the substrate, wherein the conductive fence has a second height that is lower than the first height; and a flexible electromagnetic shielding layer that covers the electronic component and the conductive fence.
