Note: 1 oz/ft 2 of copper = 0.035 mm thickness It works fine with FR4, but is not yet proven for all available materials. Please give us feedback on your use of this calculator, good or bad. This calculator is intended to be used with the Accurate Method for Measuring Relative Dielectric Constant of a PCB Using a Vector Network Analyser The default values in the text boxes relate to the samples used in the article Measuring Relative Dielectric Constant using parallel plate method and a Vector Network Analyser The approximate ε r could be from the manufacturers/suppliers specification or just left at the default of 4.2, but in extreme cases when the first sample size it is totally inappropriate it may mean repeating the process and performing the measurement on a second sample size. The optimum size of a circular PCB sample for the measurement of ε r can be calculated by entering the known dimensions and approximate ε r into the text boxes. In order to make an accurate measurement of the relative dielectric constant (ε r ) of a circular sample PCB, it is important to ensure that skin effect has become established, that edge effect is taken into account in the calculations and that the measuring instrument (VNA) is reasonably well impedance matched.
