An overmolded electronic assembly includes a substrate, a plurality of
surface mount technology (SMT) integrated circuit (IC) chips, a plurality
of heat sinks, a backplate and an overmold material. The substrate
includes a plurality of conductive traces formed on a first surface of
the substrate. The IC chips each include an active front side and a
backside and the IC chips are electrically coupled to one or more of the
traces. The heat sinks are each in thermal contact with the backside of a
different one of the IC chips and are independent of each other. The
backplate is attached to a second surface of the substrate, which is
opposite the first surface of the substrate. The overmold material covers
the first surface of the substrate and maintains the heat sinks in
thermal contact with an associated one of the IC chips.
