Abstract: A universal burn-in fixture including a printed circuit board having a plurality of regularly spaced areas and with each area receiving a semiconductor socket and with the socket having lead members for connection to the board through a plurality of holes and with the majority of the holes surrounded by a conductive pad area which form islands and with each pad surrounded by an insulating area and with the remaining portion of the printed circuit board forming a conductive land area and with substantially the entire printed circuit board covered by a resistive coating to produce resistances between each pad and the surrounding land, to provide for desired resistances between a socket lead and the land area. A voltage is coupled to the land area to supply the desired burn-in voltage at the socket leads.
