System and methods for grounding electronic components using interconnected fasteners

Abstract

The disclosure describes an interlocking grounding fastener system for a compact electronic device. In some embodiments, the system includes a first grounding fastener and a second grounding fastener configured to create a low-impedance electrical grounding connection between one or more of an antenna, a heatsink, a middle heat spreader, a bottom heat spreader, and a PCB. The first grounding fastener includes a driver engagement recess and/or threads for secure attachment to the second grounding fastener, while the second grounding fastener includes a shank with both fastening and non-fastening portions in some embodiments. These fasteners create an interlocking grounding fastener system that electrically couples the heatsink, the middle heat spreader, and the bottom heat spreader to form a grounding framework. In some embodiments, the grounding framework ensures efficient signal radiation and reception, as well as a robust grounding path for the antenna and/or PCB.
