Abstract

A method of making a resin encapsulated pin grid array which includes an IC chip mounted on a resin substrate having a plurality of contact pins on its lower surface and resin-encapsulated by injection molding. A metal heat radiating member is integrally formed on the upper surface of the encapsulating resin when the encapsulating resin is injection-molded.
