Abstract

The paper presents a method to find the effective thermal conductivity and effective volumetric heat capacity values of PWBs from the results of thermal transient measurements and a series of subsequent evaluation steps. Various powering and temperature sensing methods were investigated. The experiments show the feasibility of creating a method for obtaining effective thermal parameters of printed wiring boards with the help of usual thermal transient testers
