INSERT-MOLDED ELECTRONIC MODULES USING THERMALLY CONDUCTIVE POLYCARBONATE AND MOLDED INTERLOCKING FEATURES

Disclosed are insert-molded electronic modules that include an electrical/electronic component and a heat sink that interlocks with, and optionally also encapsulates, the electrical/electronic component to provide thermal management for the component. The heat sink is formed using a thermally conductive thermoplastic polymer composition and replaces the potting compound and thermal interface material typically used in such assemblies. The electrical/electronic component includes openings that allow the thermally conductive thermoplastic polymer composition to flow therethrough and interlock with the electrical/electronic component. The electronic module may include an insert positioned between the electrical/electronic component and the heat sink, wherein the insert includes holes that allow the conductive thermoplastic polymer composition to flow therethrough and interlock with the insert.
