Abstract

A test clip for a plastic leaded chip carrier (PLCC) includes a plurality of electrical contacts for electrically connecting with respective leads of the PLCC, an electrically non-conductive body for supporting such contacts in spaced-apart positions, and a retaining mechanism for holding the test clip in operative position with respect to the PLCC. The retaining mechanism includes plural latching arms at respective corners of the test clip and a slide actuator therefor. The slide actuator also is operative to deflect the contacts from a normally open position to a closed position engaging respective leads of the PLCC.
