Abstract
The present disclosure is related to a heatsink and a method for forming a heatsink. In one embodiment, a method for forming the heatsink includes forming at least one thermo pyrolytic graphite element. The at least one TPG element includes a first side having a wedge-shaped surface and a second side having a flat surface. The method further includes layering a metal material over the at least one TPG element, the metal configured to be complementary to the first side of the at least one TPG element, and applying pressure to fasten the metal material to the at least one TPG element.
