ABSTRACT:
A multilayer ceramic circuit board comprises a core of high conductivity material such as metal and an overlying layer of electrically insulating ceramic having an outer surface. In accordance with the invention, a circuit board for receiving a high power component is provided with a thermal spreading layer on or near the outer surface and one or more thermal vias through the ceramic to thermally couple the spreading layer to the core. The vias and the spreading layer comprise electrically insulating thermally conductive materials. The resulting structure provides rapid heat dissipation for a high power component formed or mounted on or near the spreading layer.
