摘要: Systems and arrangements to assess the thermal performance of a thermal solution based upon the ability of a device under test (DUT) to operate in accordance with electrical performance criteria are contemplated. Embodiments may include a tester to couple with the DUT to determine an operating junction temperature. In some embodiments, the measured junction temperature may be the operating junction temperature anticipated for the DUT in a customer installation. In other embodiments, the tester may comprise logic to calculate a projected, operating junction temperature based upon the measured junction temperature and known differences between the tester and a customer installation. Upon determining the operating junction temperature for the DUT at the customer installation, the operating junction temperature is compared against a maximum junction temperature for proper operation of the DUT. Advantageously, the maximum junction temperature may be varied based upon the project objective for a line of DUTs.
