Abstract
A burn-in tower having a skeletal frame which defines an outer wall is rotatably secured to a fixed base. A plurality of DUT positions are provided on the surface of the tower. Each DUT position comprises a thermal conductive module and a DUT socket assembly which are releasably engaged on to the other. The temperature of the DUT at each DUT position is controlled independently. The load applied to the DUT at each position may be the same or different. The tower is used at ambient temperatures. In a preferred embodiment, DUT mother boards which contain the driver electronics define the surface or walls of the tower.
