Abstract
A fine pitch test clip is provided, which assures accurate alignment of the test lead contacts with the IC (integrated circuit) device leads. The test clip includes a center for lying over the IC body and four arms (e.g. 41 in FIG. 4 ) pivotally mounted on the center, with each arm including a row of contacts (52) mounted in the arm housing. Lower portions of the contacts, which engage the IC device leads (30), are separated by barriers of the housing with endmost barriers (106, 108) being positioned so they can engage the endmost leads (30E) of the IC device to assure alignment of the lower contact portions with the IC device leads. A rigid board (204, FIG. 11) with connectors (211-214) thereon is mounted on the center of the test clip frame, above the arms, and flexible resilient circuit boards (231-234) each extend in a horizontal loop between the top of the contacts that lie at the top of an arm, to the rigid board where they are coupled to terminals of one of the connectors on the rigid board.
