Abstract

An input/output pin 1 (Fig. 1) of a pinned substrate 2 has an embossed flat 3 which maintains the desired distance (standoff) between the substrate 2 and a printed circuit board 4 to which the pin is mounted. (Image Omitted) In a pin of smaller cross-sectional area in which an embossment would not be the proper design, a formed standoff in the pin ensures the desired distance between the substrate and the board. The pin is formed as described in the following. As shown in Fig. 2, a pinned substrate 2 is inserted into a forming device consisting of an initial form block 3, a former mechanism 4 and a finish form block 5. The standoff 7 is formed as the former 4 drives into the pin 6 (Fig. 3). The form block 3 is retracted (Fig. 3), and the finish form block 5 drives upward to complete the standoff (Fig. 4).
