ABSTRACT:
A package for heat dissipation of electronic components mounted on a strip of thermally conductive material. A plastic body is molded to encapsulate the component and strip with extended mold ejector pins employed to form a recess such that access to the thermally conductive strip is obtained. An external heat sink is mounted onto the plastic body. A clip or through bolt establishes thermal contact between the external heat sink and the internal thermally conductive strip.
