Abstract

The terminals of a device under test (DUT) are temporarily electrically connected to corresponding contact pads on a load board by a series of electrically conductive pin pairs. The pin pairs are protected against damage from balls on a DUT by a protective ball guide which includes recesses for receiving part of the ball but prevents the ball from driving the pins beyond a limited range. The ball guide provides fine alignment horizontally and vertically enabling stable electrical performance.
