Abstract: In one embodiment, an eye of needle (EON) press-fit pin includes a base, a tip, and a compliant portion extending longitudinally between the base and the tip and comprising a pair of resilient deformable arms joined at opposite ends and defining an opening therebetween. The arms each include an outer surface for at least partial engagement with walls of an electrical via upon insertion therein. The outer surface of each of the arms includes a central segment having a flat longitudinal surface and converges from the central segment towards the base and the tip. The arms each further include an inner surface defining the opening and forming an elongated portion at each end of the opening for stress relief.
