1. A power dissipation apparatus comprising:
- a metal matrix composite liquid cooled heatsink structure comprising a base and a lid;
an electrical isolation material positioned on and directly bonded to the metal matrix composite liquid cooled heatsink structure, the electrical isolation material having a first major surface, a second major surface, and a layer of conductive material disposed on the first major surface, wherein the second major surface contacts the metal matrix composite liquid cooled heatsink structure, and wherein the electrical isolation material is integral with the metal matrix composite liquid cooled heatsink structure and non-solder boned to the metal matrix composite material via a metal of the metal matrix composite liquid cooled heatsink structure which metal infiltrates said heatsink structure; and
an electronic circuit positioned on the layer of conductive material disposed on the electrical isolation material.
