Abstract:
A surface-mounted integrated circuit (IC) package is disclosed that has unwanted flux removed from surface-mounted IC. A bottom termination component (BTC) includes lands and a thermal pad. The lands provide an electrical connection from the BTC and the thermal pad provides heat transfer from the BTC. The thermal pad includes vias that are configured to remove flux generated from solder applied to the surface-mounted IC as the surface-mounted IC is assembled. A printed circuit board (PCB) is mourned to the BTC and is electrically connected to the BTC via the lands and receives heat transfer from the BTC via the thermal pad and includes a reservoir. The reservoir is configured to pull flux positioned between the lands into the reservoir as the flux is generated from the solder applied to the surface-mounted IC as the BTC is mounted to the PCB and as the surface-mounted IC is assembled.
