Claim Text:
1. An integrated circuit (IC) device tester configured to maintain a set point temperature on an IC device under test (DUT) having a die attached to a substrate, the tester comprising: a test socket assembly having: a test pedestal assembly configured to contact a die of the DUT; a heat exchange plate configured to facilitate the heat conduction to and from the heat-conductive test pedestal assembly and having an attached temperature sensor for monitoring the temperature; a temperature-control fluid circulation block having a fluid inlet and a fluid outlet configured to circulate a fluid therethrough, the block in stacked relationship along a z-axis with the heat conductive test pedestal assembly; a thermally-conductive heater between the heat exchange plate and the fluid circulation block configured to provide heat to the test pedestal assembly through heat exchange plate; a substrate pusher configured to contact the substrate of the DUT; and a controllable force distributor configured to receive a z-axis force and controllably distribute such z-axis force between the test pedestal assembly and the substrate pusher.
