Abstract:
1. A method of fabricating a circuit board comprising the steps of: providing a thermal management material, applying an electrically insulating layer to at least one surface of said thermal management material, applying an electrically conductive material to said one electrically insulating layer and laminating said thermal management material, said electrically insulating layer and said electrically conductive material together with heat and pressure wherein the method of making said thermal management material further comprises the steps of cutting a thermally conductive substrate from a larger sheet of heat conducting material, degreasing said thermally conductive substrate, mechanically abrading at least one surface of said thermally conductive substrate, acid cleaning said at least one abraded surface of said thermally conductive substrate, rinsing said thermally conductive substrate, passivating said at least one abraded surface of said thermally conductive substrate to render said at least one surface chemically inert, rinsing said thermally conductive substrate, drying said thermally conductive substrate and baking said thermally conductive substrate at an elevated temperature.
