Thermally conductive board
Abstract:
A thermally conductive board comprises a metal substrate, a foil containing copper, a thermally conductive and insulating layer and a barrier layer. The thermally conductive and electrically insulating layer is disposed on the metal substrate. The barrier layer is laminated between the foil containing copper and the thermally conductive and electrically insulating layer. The barrier is in direct contact with the foil containing copper, and the interface between the barrier layer and the foil containing copper comprises a microrough surface. The barrier layer has a Redox potential between 0 and −1V. The microrough surface has a roughness Rz of 2-18 μm.
