Abstract:
A heat sink and method of fabrication are provided for removing heat from an electronic component(s). The heat sink includes a heat sink base and frame. The base has a first coefficient of thermal expansion (CTE), and includes a base surface configured to couple to the electronic component to facilitate removal of heat. The frame has a second CTE, and is configured to constrain the base surface in opposing relation to the electronic component, wherein the first CTE is greater than the second CTE. At least one of the heat sink base or frame is configured so that heating of the heat sink base results in a compressive force at the base surface of the heat sink base towards the electronic component that facilitates heat transfer from the electronic component. A thermal interface material is disposed between the base surface and the electronic component.
