ABSTRACT:
A stiffener for a printed circuit board which comprises an elongated metallic electrically conductive bar. Extending from the bar are a plurality of spaced apart pins with these pins being in longitudinal alignment. Each pin is constructed to facilitate physical deformation such as by including a through opening within the body of the pin or with the pin including notched-out areas in the side walls of the pin. Upon the pin incurring a sufficiently powerful striking force, the pin will deform and expand laterally.
