ABSTRACT:
A new electrical connector system employs two printed circuit board type connector components (1 & 3), each containing a plurality of plated-on metal lines (11 & 13) running along the board in parallel, and a replaceable contact element (9), termed an interposer, that is sandwiched between those printed circuit boards. The interposer contains malleable electrical contacts (15 & 17) on each side that extend electrically from one surface to the other and serves as a contact bridge for those connector contacts. The interposer is formed as a thin insulator strip and metal bumps on the top and bottom sides of the strip serve as the electrical contacts. Bridging connection for metal bumps on the top side with associated bumps on the bottom side is served with plated-through holes (16). The metal bumps are of Indium and Tin that is covered by a flash of Gold. Ancillary to the described connector, a new method for constructing an electrical connector is also presented.
