Overmolded electronic assembly

摘要

An overmolded electronic assembly (10) and method for forming the assembly (10). The assembly (10) includes a heat-conductive member (18) in thermal contact with one or more circuit devices (16) mounted to a circuit board (12). An overmolded body (22) encloses the circuit board (12) and the circuit devices (16) with the heat-conductive member (18), such that the overmolded body (22) and heat-conductive member (18) form a moisture-impermeable seal around the circuit board (12) and circuit devices (16). The overmolded body (22) also includes a connector housing (28) integrally-formed in its outer surface. The method for manufacturing the assembly (10) generally entails supporting the circuit board (12) with the heat-conductive member (18) such that the heat-conductive member (18) thermally contacts the circuit devices (16). An overmolded enclosure is then formed by molding a material over the surface of the circuit board (12) to form the overmolded body (22) that, with the heat-conductive member (18), encases the circuit board (12) and its circuit devices (16). <IMAGE>
