Abstract
This paper describes how to evaluate the measurement results of in-plane thermal conductiity of Printed Circuit Board (PCB) without Computational Fluid Dynamics (CFD) analysis. Previously, a measurement method of in-plane effective thermal conductivity of PCB by using one-dimensional thermal resistance measurement results include both out-of-plane and in-plane effective thermal conductivities, one more step is measurement results, CFD analysis was employed. In this paper, theoretically constructed estimate equation is employed and the possibility of the equation is discussed.
