摘要
电子设备电磁兼容要求的关键是其印制电路板(PCB)的设计,正确的PCB板布线可以经济而有效地降低其电磁干扰。文章综合PCB板电磁兼容设计相关文献,按照器件布局、地线与电源处理、时钟信号线处理等对设计经验和原则进行了较为系统的分类总结,并结合若干具体的工程实例进行了分析说明。
The printed circuit board （PCB） is the key part to meet the electromagnetism compatibility （EMC） requirements for electronic equipment. Their electromagnetism disturb can be reduced by proper layout of PCB. Some important EMC design rules are brought forward including components placement, ground plane, power line, clock signal treatments. At last, some factual examples of EMC design rules mentioned above are shown and analyzed.
