International Standard

Scope

This document defines a method for evaluating effective in-plane thermal conductivity and conductance of a metalized ceramic substrate bearing a heater chip as an imitation of a SiC power semiconductor. The method provides an indicator for in-plane heat transfer properties of metalized ceramic substrates employed in high-power modules.
