Designing a PCB for electromagnetic compliance starts with identifying and controlling the sources of unwanted EM energy. Board designers can achieve electromagnetic compatibility (EMC) by isolating noisy and sensitive circuits, maintaining continuous return-current paths, and minimizing high-frequency switching-current loops. Signal integrity engineers should evaluate the circuit board as part of the complete product. They should consider cables, interfaces, power supplies, the enclosure, and other system-level factors that can influence overall performance. Following these design guidelines can help your product pass essential tests, avoid expensive redesigns, and reach the market faster. In this article, you will learn how to ensure EMC…
