Patent abstract
Input and output of small-current signals between a mother board and semiconductor devices subjected to a burn-in test are made via a device driving unit. Large-current main power is supplied via the device driving unit through bus bars without passing through the mother board. In this way, the risk of burn-out in a burn-in substrate and burn-in sockets, and damages caused by a burn-out can be reduced even when it occurs.
