Abstract:
An overmolded electronic module comprising:a circuit board having a first surface and an oppositely-disposed second surface;a surface-mount circuit device attached to the second surface of the circuit board with solder bump connections, the circuit device being spaced above the second surface of the circuit board by the solder bump connections so as to define a gap therebetween;a heatsink thermally contacting a surface of the circuit device oppositely-disposed from the circuit board; andan overmolded body formed of an overmold material that encases the circuit board and the circuit device with the heatsink to provide a moisture-impermeable seal around the circuit board and the circuit device, the overmolded body having an underfill portion that completely underfills the circuit device and encapsulates the solder bump connections.
