Abstract

This metal part is designed to ground a socket-style heatsink to grounded solder pads on the planar. Planars are configured with 3 through-holes on each side of a processor PGA socket. This part pokes into the holes and can be mechanical retained or may be wave soldered onto the planar. Then the heatsink is clipped onto the cpu socket, which slightly deforms the grounding device and forms a solid EMI ground path. Heatsinks can radiate EMC emissions from processors and this device will ground the heatsink and lower EMC levels. 10K1533.pdf 1
