Terminal pins mounted in flexible substrates

摘要

An electronic device (52) includes a flat flexible dielectric substrate (56) less than 0.050 inch thick and having a generally round hole (58) of a given diameter (66). A substantially square or polygonal terminal pin (62) is inserted into the round hole (58) in the substrate. The pin has a given cross-dimension (64) between opposite diametral corners thereof greater than the diameter of the round hole (58). The difference between the cross-dimension (64) of the pin (62) and the diameter (66) of the round hole (58) is on the order of 7% to 67% of the diameter of the hole.
