摘　　要：随着电子技术的发展，电磁干扰越来越严重。所以，电磁兼容设计已经成为产品设计中十分重要的一项内容，在电子设备及电子产品中，电磁干扰能量通过传导性耦合和辐射性耦合来传输，为满足电磁兼容性要求，对传导性耦合需采取滤波技术，即采用EMI滤波器件加以抑制；对辐射性耦合则需采用屏蔽技术来加以抑制，电磁屏蔽已成为解决电磁兼容问题的最重要手段之一，大部分电磁兼容问题都可以通过电磁屏蔽来解决。With the development of the electronical technology, the electromagnetic interference becomes more serious, so the electromagnetic compatibility design has been a very important content of electronics. Electromagnetic interference energy is transferred through conductive coupling and radiative coupling. To meet requirements of electromagnetic compatibility, filtering technology is employed for conductive coupling, i. e. suppressing with EMI filtering devices,while radiative coupling is restrained with shielding technique. Electromagnetic shielding is a key way to avoid the electromagnetic interference, and most of the problem can be resolved by this way.
