摘要

<正>1. Introduction The EMC design for the Printed Circuit Board has been a popular topic. Guidelines and tips for high-speed PCB designs could be found from numerous resources. When investigating EMI issues associated with circuit boards, many details such as clock frequencies, switching rates, rise/fall times, signal harmonics, data transfer rates, impedances, trace loading, and types and values of the various circuit components, should be taken into considerations. The physical layout of the PC board and its associated metallic components are important considerations. Special attention should be given to the placement and characteristics of signal source components, vias,
