Understanding PCB Impedance Mismatch: Causes, Effects, and Mitigation Strategies
Introduction Printed Circuit Boards (PCBs) are the backbone of modern electronics, enabling the interconnection of various components to form complex circuits. As signal frequencies continue to rise—especially in high-speed digital, RF, and microwave applications—maintaining proper impedance control becomes crucial. Impedance mismatch is a common issue in PCB design that can lead to signal integrity problems,…
