ABSTRACT:
Integrated Circuit ("IC") handling and contact system including adjustable stacked vertical input tracks, a single moving oscillating singulatory mechanism, a contactor assembly including configurations for leaded and leadless chip carriers and pin grid arrays, a monodirectional sorter, and adjustable output tracks. The input tracks and output tracks are adjustable for width and thickness of the IC packages. The contactor assembly includes preloaded contacts for proper penetration and wiping action for each device, pad, or pin, and provides cantileaver and torsional positioning with respect to each pin of the IC packages. The system includes an environmental chamber with the electromechanical components located in a second chamber to one side thereof and coupled by actuating shafts to the environmental chamber. The output module includes a last bin grouping for ICs which fail testing.
