【摘要】 印刷线路板的布线设计对电源的EMI水平有很大影响 ,传统的布线规则往往过于笼统 ,实际工作中难以运用。本文提出了一种基于电场干扰分布图的计算机辅助布线方法 ,帮助设计人员在布线设计的过程中就能将潜在的干扰问题解决掉。文中给出了计算和实验证明。更多还原

【Abstract】 The layout design play a very important effect in the EMI level of switching power supply.Conventional layout rules are too general to handle easily.A computer aided design method is proposed.Based on electrical field emission map and coupling index PCB designer can arrange critical trace in suitable location,so potential crosstalk problem between traces can be suppressed in advance.Calculational and experimental verifications are presented.更多还原
