摘　　要：便携式电子设备的迅速发展使得印刷电路板的面积越来越小,速度越来越快,供电电压越来越低,也使得产品的电磁兼容性问题越来越突出。在印刷电路板的设计阶段使用电磁兼容技术对系统的可靠性十分重要。介绍了紧凑型PCB设计中EMC规则的应用,可有效缩短系统整改时间和提高系统的可靠性。Owing to the rapid development of portable electronic systems, the printed circuit broad（ PCB） are getting smaller, faster, and more low supply voltage, making the product more electromagnetic compatibility（EMC） problem. Electromagnetic compatibility technologies is very important for system reliability in the design phase of the PCB. This paper describes the applica-tion of EMC design rules of compact PCB,the system can effectively shorten the rectified time and improve the reliability of sys-tem.
