摘要
在印刷电路板的设计阶段进行电磁兼容性(EMC)设计是十分重要的。本文介绍了一种预测印制电路板电磁干扰(EMI)的方法,得出微机开关电源PCB板的近场分布图,并以此为参考选择布线路径。
It is very important to start EMC design during the course of PCB design. This paper introduces a method to predict EMI of PCB, gives the near field distribution map of PC switching mode power supply and arrange critical trace in suitable location.
