Abstract: To make a printed circuit board, bores bridge gaps between where conductor paths are to be located, and are then filled with an adhesive. The gaps between where the conductor paths are to be located then caustically removed so that a conductor path skeleton results which is held together by the adhesive bridges. Finally, the conductor path skeleton is affixed to an insulating layer.

Abstract: A connector pin, adapted to be inserted into a metallized bore in a conductive plate to form a solder-free mechanical and electrical connection between the pin and plate, is fabricated to provide an elongated deformable region adapted to engage the sides of the bore and consisting of two elongated beam members that are inteconnected to one another by a cross member. The cross section of the resulting deformable region may be M-shaped or W-shaped. Upon insertion of the pin into the bore, the deformable region deforms elastically and, in the case of a small diameter bore, partially plastically to provide a good electrical and mechanical connection between the pin and plate.
