Abstract
A system includes a heat sink, a semiconductor device, a layer of thermal interface material (TIM) disposed between the heat sink and the semiconductor device, and a fastener system that couples the semiconductor device, the layer of TIM, and the heat sink together. The TIM may facilitate dissipation of heat generated by the semiconductor device via the heat sink during operation of the semiconductor device. The fastener system includes a first Belleville-type washer configured to cooperate with the TIM, which flows when heated beyond a threshold temperature, to maintain a substantially constant coupling force between the semiconductor device and the heat sink during operation of the semiconductor device.
