Even the most carefully designed High-Frequency PCB can experience variations in electrical performance after fabrication. Although modern computer-aided engineering (CAE) and electromagnetic (EM) simulation tools can predict circuit behavior under carefully defined conditions, simulation results are only as accurate as the manufacturing parameters used in the model. In practical PCB…
