Abstract
An active temperature control system for a DUT utilizes a heat sink containing HFE7100 liquid and an electric heater. The liquid is cooled below the set point and the heater is used to bring the DUT up to the set point. Set points in the range of −10 degrees C. to +110 degrees C. can be achieved. The heat sink utilizes only a single coolant for all of the set points, allowing set points to be changed within a few minutes. At a given set point, the heater provides a quick response to offset the effect of self-heating and keep the set point deviation to within a few degrees C. Power following techniques can be utilized to achieve the quick response.
