Abstract
An overmolded electronic module and a method for forming the module. The method entails both overmolding a circuit board and underfilling one or more surface-mount circuit devices physically and electrically connected to the board with solder bump connections. The circuit board is supported on a heatsink that thermally contacts a surface of the device opposite the circuit board. The board is optionally then encased on the heatsink with a retainer that includes means for biasing the circuit device against the heatsink. Finally, the circuit board is overmolded with a polymeric material to form an overmolded body that encases the circuit board and the circuit device with the heatsink. The overmold process is carried out so that a portion of the overmolded body completely underfills the circuit device and encapsulates its solder bump connections.
