Abstract

The measurement technique of thermal impedance at an interface has been developed using the sample with a dummy thermal impedance. 304-series stainless steel with different thicknesses was utilized as a test material and was attached to copper blocks by Stycast 2850FT which is for adhesive and for dummy thermal impedance. The apparent thermal conductivities of the samples were measured at the range from 15 K to 250 K. Any two thicknesses of them were compared, and the information on the thermal conductivity of stainless steel and on the thermal impedance of the Stycast layer were extracted. According to the results compared with that of other studies, it was confirmed that the comparison between the samples with different thicknesses was one of the useful techniques to obtain the information on the thermal impedance.
