ABSTRACT:
The automatic loading and unloading of devices for burn-in testing is facilitated by loading burn-in boards in a magazine with the stacked boards in the magazine moved into and out of a burn-in oven by means of a trolley. The trolley can include an elevator whereby a plurality of magazines can be stacked in the oven for the simultaneous burn-in testing of devices mounted on the burn-in boards. Each board has rollers on one end which are engagable by pneumatically actuated cam mechanisms for inserting the board into an electrical contact in the oven for burn-in tests. Preferably, the cam mechanisms allow for extraction of a single board for inspection.
