An accurate method for measuring the dielectric constant of printed wiring board materials

An accurate method for measuring the dielectric constant of printed wiring board materials A new timedomain reflectometry measurement method is described that provides accurate measurements of the average highfrequency 0.1GHz 10GHz dielectric constant of printed wiring board materials and is suitable for factory floor use. A parallelplate transmission line is used for the sample geometry. Only simple numerical processes are required to extract the characteristic impedance and dielectric constant of the sample from the acquired data. The longterm measurement reproducibility and shortterm measurement repeatability of the method are described. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Circuit World Emerald Publishing

Abstract

A new timedomain reflectometry measurement method is described that provides accurate measurements of the average highfrequency 0.1GHz 10GHz dielectric constant of printed wiring board materials and is suitable for factory floor use. A parallelplate transmission line is used for the sample geometry. Only simple numerical processes are required to extract the characteristic impedance and dielectric constant of the sample from the acquired data. The longterm measurement reproducibility and shortterm measurement repeatability of the method are described.
