Technique for enhancing adhesion capability of heat spreaders in molded packages

摘要

Adhesion between a heat spreader (15) and a substance (19) to be adhered to the heat spreader can be enhanced by using thermal spray deposition or flame plasma deposition to apply a coating (23) to the heat spreader. The substance to be adhered is applied to the coated heat spreader. The technique can be used in all electrical circuit assemblies.
