ABSTRACT:
A thermal control unit (TCU) for maintaining the set point temperature of an IC device under test (DUT) has a thermoelectric module (a Peltier device), a fluid circulation block, a lower pedestal assembly containing a thermal sensor, and an upper cover housing arranged in a stacked relationship along the z-axis of the TCU. A z-axis compliant force is supplied from the TCU's cover housing by means of a spring-loaded pusher mechanism that supplies a compliant spring force to the stacked arrangement of the fluid block, peltier device, and pedestal assembly. The z-axis compliant force provided by the spring-loaded pusher mechanism produces efficient thermal contact between the peltier device and the stacked components of the TCU containing the peltier device and allows the peltier device to expand and contract within the TCU to extend the life of the peltier device. An alternative quick disconnect feature allows the electrical leads of the thermal sensor in the pedestal assembly to automatically make electrical connection with associated wiring in the cover housing when the cover housing is secured to the pedestal assembly.
