To the pcb , here detailedly introduce all kinds of disturb , sensitive element and the coupling modes of transmit . here mainly analyse the master coupling route ( the trace of the pcb ) and the shield of crust in theory , set up the models of them include the study on the effect of an external electromagnetic interference on a pcb trace , the study on the effect of an hole leak electromagnetic interference on a pcb trace and the study on the crosstalk analysis between two transmission - lines of pcb 详细介绍了pcb上的电磁兼容原理,对于主要耦合干扰途径(对pcb上走线的耦合)和pcb的外壳屏蔽进行了详细的理论分析及推导,对pcb板上微带线走线的各种耦合情况和外壳屏蔽进行了建模,包括外电磁场对走线的耦合、孔缝泄漏场对走线的耦合、走线之间的串扰等情况。
