Claim 0:
1. An apparatus for thermal control of a device under test (DUT), the apparatus comprising:
a cooling structure operable to provide cooling, said cooling structure operable to inlet cooling material via an inlet port thereof and operable to outlet cooling material via an outlet port thereof;
a variable thermal conductance material (VTCM) layer disposed on a surface of said cooling structure;
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, and 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 a thermal conductance of said VTCM layer.
