Abstract
A vacuum pickup arrangement, particularly for a pick and place system for automated testing of integrated circuits, employs a resilient, bellows-like retractable device for making a secure vacuum-tight engagement with the integrated circuit specimen. The creation of the vacuum-tight engagement causes axial collapse of the bellows-like arrangement whereby the specimen is brought into communication with one or more protuberances or edges which define a predetermined angular orientation of the integrated circuit specimen desired to be achieved. Laterally disposed alignment jaws are employed to align the integrated circuit specimen with a test socket at a remote location. However, when the specimen is returned, the resilient nature of the bellows automatically realigns the integrated circuit specimen with the location at which it was originally picked up.
