Heat sink interface having three-dimensional tolerance compensation

摘要

A thermal interface includes a plurality of elevated regions and a plurality of mechanical tolerance circuits coupled to the plurality of elevated regions. The thermal interface is configured to be disposed between an array of heat generating elements and a heat sink with each of the plurality of elevated regions thermally coupled to a corresponding one or more of the array of heat generating elements. In one embodiment, the thermal interface provides a thermal path between a printed wiring board having a plurality of flip-chip circuit components disposed on an external surface thereof and a heat sink disposed over the flip-chip circuit components.
