摘要
本文对使用EDA软件设计PCB的过程中,根据印制导线产生电磁干扰机理,从PCB设计中导线的布置原则、板型和密度的选择、线宽和间距的选择、走线形式的选择、电源线和地线的处理等方面,介绍了排除和预防PCB布线电磁干扰的方法和措施。
This paper uses the design PCB processing of EDA software,according to the mechanism of electromagnetic interference with printed cabling from the PCB design layout principle of the wire,the choice of plate type and density,selection of line cabling and spacing,linear form choice,the power cord and ground handling etc.,introduces the ways and countermeasures to get rid and prevent of PCB cabling electromagnetic interference.
