ABSTRACT:
An automatic loading and unloading support for use on the interior of a burn-in oven includes a frame that supports a rack of printed circuit burn-in boards connected to connectors along edges of the burn-in boards at one end of the rack. The frame has a track for supporting the rack for movement from an open end toward a closed end of the oven. Driver/receiver boards are mounted at the closed end and have connectors aligning with the connectors on the burn-in boards on a rack. When the rack is moved to a position closely adjacent to the driver/receiver board connectors, alignment pins will align the rack properly and then actuators are used for moving inserter bars that press against the back side of the rack and push the connectors on the burn-in boards into the connectors on the driver/receiver boards. After the burn-in test is complete, and the rack is to be removed, the actuators will first move the inserter bars to clear the opening at the open end of the frame and then actuate ejector bars to push the rack and the supported burn-in boards in a direction to uncouple the connectors of the burn-in boards from the connectors on the driver/receiver boards.
