Abstract:
1. A system for mounting a heat sink to a CPU located on a first side of a PCB, comprising: a plurality of holes on the PCB, the holes defining passageways through the PCB; a plurality of studs mounted to the heat sink, the plurality of studs extending through the PCB via the passageways defined in the PCB; a spring element mounted to each of the plurality of studs on a second side of the PCB; a thrust plate mounted on the spring element, the thrust plate configured to press against the second side of the PCB, whereby the spring element exerts a force on the thrust plate that causes the thrust plate to press against the second side of the PCB, thereby causing the CPU to press tightly against the heat sink; and a plurality of EMI gaskets mounted to the plurality of holes of the PCB, the plurality of EMI gaskets located between the PCB and the heat sink, wherein the plurality of studs extend through the plurality of EMI gaskets.
