Claim Text:
1. A system for thermal management of test pins in a test array configured to test a device under test (DUT), the test pin array having first ends configured to contact a load board having a plurality of aperture and second ends of said pins configured to contact the DUT, the system comprising: a. an active heat transfer device having two surfaces capable of transferring heat or cold from one surface to the other, b. a heat exchanger device atop said heat transfer device, said exchange device having at least one surface in contact with on face of said transfer device and having a fluid passage therethrough to supply thermal fluid through the device; c. a contact plate in abutment with said heat transfer device on one surface and the load board on an opposite surface; d. an alignment plate located adjacent the load board on a load board face opposite of said contact plate; said alignment plate including an aperture having a peripheral edge for receiving a test pin array; e. a plurality of thermal transferring legs sized to pass through said apertures on the load board, said legs extending from said alignment plate to said contact plate and providing a thermal circuit; said legs further including through going apertures f. Nozzles fitted into at least one of said aperture in said legs; whereby test pins are thermally managed by the thermal circuit from the heat transfer device to the test pins through the load board and whereby dry air supplied to the nozzles minimizes condensation at the pin array.
