Anotace
This part of IEC 63609-2 specifies the method for evaluating the thermal conductivities in the in-plane and thickness directions of circuit boards such as FR-4 and CEM-3 made of polymer composites.
This document applies to circuit boards made of polymer composites with thermal conductivities from 0,1 W·m-1·K-1 to 10 W·m-1·K-1 and thicknesses from 0,5 mm to 3,0 mm.
This document specifies the method for constructing a representative volume element (RVE) model and the method for determining the in-plane and thickness thermal conductivities using finite element analysis with the RVE model.
The methods for measuring thermal conductivity used to verify the validity of the results obtained from finite element analysis using the RVE model referred to in this document are the standardised steady-state method and the laser flash method. This document describes the specimen preparation method, the measurement conditions and the measurement procedures.
