ABSTRACT:
A fixturing system including a product access unit, receiver and support bracket. The product access unit has a top plate upon which the product under test is placed, which top plate is movable so as to carry the product under test into contact with a field of test probes. The product access unit also has a contact panel disposed outboard of the field of test probes, said contact panel containing electrical contact posts wired to the test probes. The contact panel is provided with mating guides and the receiver includes mechanical means for engaging and locking with these guides. The support bracket includes sockets which co-operate with guide pins on the product access unit for aligning it for assembly with the receiver. The product access unit is vacuum-operated and a perimeter gasket on the top plate forms a seal with an inwardly sloping portion of the housing containing the vacuum plate.
