摘要
印制电路板上的电磁干扰主要是电源布线和信号布线产生的。抑制电源布线产生的干扰的主要方法有电源平面法、共地平面法和电源母线法;抑制信号布线产生的干扰的主要方法是增大信号线之间的距离,减小信号线与地之间的距离。同时,设计印制电路板还应遵循一定的抗干扰原则。
Electromagnetic intergerence and suppression of plated circuits panel is mainly produced by the power wiring and the signal wiring. The main methods that produce the disturbance by the suppression of power wiring are the power plane law, altogether horizon law and power generatrix law. And the main methods of controlling the disturbance by the blanketing wiring are to increase the distance of the holding wires and to reduce the distance between the holding wires and ground. At the same time, the design of plated circuit board also should follow certain anti-interference principle.
