Abstract:In this paper, with a view to the development of high speed electronic design technology and the criterion of EMC, the general conception of EMC was introduced, then the importance of EMC in PCB design and common represented forms of EMI were discussed ,and then the techniques of avoiding EMI in PCB design to measuring up the criterion of EMC were shown in detail. The common methods of preventing EMI in higher speed PCB design was put finally.
