Electromagnetic Compatibility of Circuit System Design

Abstract

As automobiles, communication equipment, computers, and electrical equipment enter the home, the electronic devices are leading to a dramatic increase in space electromagnetic energy, and the electromagnetic environment is deteriorating. Therefore, the world attaches great importance to electromagnetic environment which is becoming more and more complex. And the broad influence of this subject is prompting environmental magnetism and electromagnetic compatibility technology to develop rapidly. The article mainly introduces the concept of EMC and emphatically analyzes the shielding design, signal and power integrity of PCB board design. Meanwhile, this article summarizes EMC test technology.
