Claim 10:
11. An apparatus for thermal control of an electronic device under test (DUT), the apparatus comprising:
a cooling structure operable to provide cooling and comprising an inlet port and an outlet port, said cooling structure operable to inlet cooling liquid via the inlet port thereof and operable to outlet cooling liquid via the outlet port;
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 signal, 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; and
a compression mechanism for providing compression to said VTCM layer to vary said thermal conductance characteristic thereof.
