摘　　要：介绍了电磁干扰的种类、途径。通过合理的布局、布线降低了印制电路板上各电子元器件之间的干扰，可在各种工业现场、恶劣的电磁环境中使用：通过实验证明采取电磁兼容设计的电路板工作稳定、可靠，基本解决了设备往常出现的误动作现象。This paper introduces the kinds and approaches of electromagnetism disturbance. The interference of various electronic components on the printed-circuit board can be reduced by means of rational arrangement and wiring. This printed-circuit board has been used in various industry sites or bad electromagnetism environment. It is demonstrated from the experiment that the circuit board adopting the design of electromagnetic compatibility works stably and reliably. It has generally resolved error-action phenomena that often appear in devices.
