A method of forming electrically conductive pins.

摘要

A method of forming electrically conductive pins for printed circuit boards from strip or sheet metal or metal alloy comprises the following steps:- (a) shearing the strip or sheet to form a carrier strip (1) and pin profiles (2), each pin profile having a defined portion (3) for becoming the compliant section of the pin, and each profile being attached to the carrier strip; (b) coining the defined portion of each pin to increase its surface area; and (c) folding the defined portion of each pin to form the required cross-sectional shape of the compliant section.
