Experimental Validation Methods for Thermal Models

The present paper evaluates the most important experimental thermal characterisation techniques for electronic components. Weak points are indicated in the standardised methods for the still air, cold plate and fluid bath environment. Improvements have been developed: Suitable measures determine well-controlled surface temperature profiles over the whole component surface in the double cold plate. Two impinging jets impose reproducible heat transfer coefficients in the fluid bath method. Hence, the reproducibility, the scope and the accuracy of the measurements are enhanced.
