1 Scope

This document describes the use of a Split Dielectric Resonator (SPDR) to measure the thermal conductivity of laminates at discrete frequency points in the range of 1.1 GHz to 20 GHz.

The method of relative dielectric constant (Dk or epsilonr) and dielectric loss tangent (Df or tandelta).

This document applies to the testing of copper clad laminates and insulating dielectric substrates for printed circuit boards.
