Scope
This document describes the test method for measuring the thermal conductivity of high-thermal-conductivity ceramic substrates from room temperature to 300°C using the flash method.
This document is applicable to homogeneous high-thermal-conductivity ceramic substrate materials with a thickness of 0.1 mm to 1 mm and a thermal conductivity at room temperature ranging from 50 W/(m·K) to 2,000 W/(m·K).
