ABSTRACT:
A contactor assembly interconnects a surface mount integrated circuit device under test (DUT) with a test circuit. The assembly includes a main contact block with a central opening, a plug that mounts in the opening, and contact assemblies carried on the plug that each have contacts, a ground plane, and an insulating layer therebetween. Alignment pins locate the contact assemblies on the plug and other pins locate the plug within the contact block opening. The upper end of the contacts, cooperating with the plug, project freely toward a contact plane where they connect with associated pins of the DUT. The lower end of the plug simulates the DUT for insertion into a socket on the test circuit. Laterally adjustable conductive clips connect each ground plane to a ground member connected to the test circuit and located around the socket. In the preferred form, a rectangular frame of an insulating material surrounds the DUT-simulating portion of the plug and clamps pairs of these adjustable clips, one of which resiliently abuts the lower end of the ground plane of the associated contact assembly, and the other of which resiliently bears against the ground member.
