  • Publication number: 20140236528
    Abstract: A measurement method for a junction-to-case thermal resistance is provided. First, a first transient cooling curve of the chip for the semiconductor device under test (DUT) without grease is measured. Then a second transient cooling curve of the chip for the DUT with grease is measured. A difference ?T of temperature variations of the two transient cooling curves with and without grease is calculated. The temperature of a constant temperature cold plate for fixing the semiconductor DUT is increased by ?T, and a third transient cooling curve of the chip for the DUT with grease is measured again. The first transient cooling curve and the third transient cooling curve are used to calculate the junction-to-case thermal resistance.
