Abstract

Abstract This invention features lead frames, molded lead frames and adapters (10) and sockets produced by molding these lead frames. In general, the lead frames comprise a frame and a circuit, wherein the circuit comprises a plurality of electrical conducting elements (12). The elements are held in position by the frame, and each element comprises an area within the element suitable for positioning a pin (26) through the element to electrically connect the element with the board. The lead frame can be molded in plastic and trimmed to remove the frame to leave each element electrically separate from each other element.
