ABSTRACT:
A process of making a heat-sinking structure, which includes providing a mold having cavities closed at one end and open at another end, the cavities corresponding to the heat dissipating surfaces on the heat-sinking structure, at least partially evacuating ambient gases from the cavities by applying a vacuum to the open end of the cavities, filling the mold with molten material when the mold is substantially evacuated by introducing the thermally conductive material into the mold at the open end of the cavities, and solidifying the thermally conductive material in the mold and removing the resultant molded heat-sinking structure. A combination electromagnetic interference filter and electrical socket assembly is also provided that includes an electromagnetic interference filter, at least one conductive, single-piece, electrical terminal blade passing through the electromagnetic interference filter, and a block of electrically insulating material. The terminal blade provides an electrically conductive path and also provides a connection mechanism configured to inter-fit with another electrical conductor. The electromagnetic filter comprising the single-piece electrical terminal blade is molded into the block of electrically insulating material to form an electrical socket. The single-piece electrical terminal blade passes through the block of electrically insulating material and has exposed ends.
