ABSTRACT:
A circuit board pin in which the compliant portion has two beams spaced apart on each side of a slot. The beams have outward facing surfaces which are convex in lateral cross-section. In plan view and in side elevational view the convex surfaces extend outwardly beyond parts of the pin lying next to the compliant portion and in both views also the compliant portion tapers down onto these other parts of the pin beyond ends of the slot. The compliant portion is made from a preform having two beams by applying a deforming pressure against outer lateral edges of the beams and towards the slot to deform the beams inwardly while narrowing the slot and expanding the beams outwardly in side elevation.
