Abstract
Abstract A compliant portion of the tubular body of a compliant pin is configured with an elliptical cross section. Preferably, the tubular body is seamless but alternatively may have a seam with the edges of the seam connected together. The configuration is particularly useful for micro-miniature pins. In the preferred method embodiment, on one side of a member to which the pin is to be affixed, the leading end of a blank tubular pin is inserted into the mating receptacle of the member and such that the blank pin provides a protrusion or extension on the opposite side of the member. A compliant section with an elliptical cross section if formed in a predetermined part of the protrusion and thereafter the pin is partially retracted into the receptacle so that the compliant section coacts with the receptacle to affix the pin to the member.
