Claim 18:
19. An apparatus for performing thermal control and testing of a device under test (DUT), the apparatus comprising:
a cooling structure operable to provide cooling;
a variable thermal conductance material (VTCM) layer disposed on a surface of said cooling structure, wherein a thermal conductance characteristic of said VTCM varies with compression thereof;
a heater layer operable to generate heat based on an electronic control, and wherein said VTCM layer is operable to transfer cooling from said cooling structure to said heater layer;
a thermal interface material layer disposed on said heater layer, wherein said thermal interface material layer is operable to provide thermal coupling and mechanical compliance with respect to said DUT;
a computer system for implementing a method of testing said DUT, said method comprising:
applying input test signals to DUT; and
retrieving output signals from said DUT responsive to said input test signals.
