Thermal control using phase-change material

Abstract:

An example test system includes: a test slot to hold a device under test (DUT); a temperature control system comprising a phase-change material, with the temperature control system for maintaining a temperature of the phase-change material in a steady-state condition, with the phase-change material changing phase during a transient condition to affect a temperature of a thermally-conductive structure, and with the steady-state condition being longer in duration than the transient condition; and an air mover to direct air over the thermally-conductive structure and towards the DUT in the test slot in order to affect a temperature of the DUT.
