The short-pulse propagation (SPP) time-domain technique is shown to be able to easily account for the inhomogeneities found in typical printed-circuit-board wiring. SPP is used to generate broadband predictive models for differential lines with different glass-fiber-to-epoxy-resin ratios and also for the soldermask layers used on top and bottom of typical boards. In both cases, a two-step extraction procedure is employed to obtain the broadband complex permittivity for the inhomogeneous… CONTINUE READING
