A very compact electrical test contactor assembly design for a handler is described that gives a means to better match the temperature of the contactors (-60 degC to 160 degC) and the devices under test (DUTs). The resulting design aims for tight temperature control (? 1 degC) of DUTs while minimizing the electrical transmission path length (~ 2.5 cm). A high thermal conductivity plate uses direct current (DC), electric resistance heaters and liquid nitrogen (LN2) to control the contactor temperatures. Tests at 90 degC confirm expected hot-temperature performance.
