提高印制电路板的抗干扰能力及电磁兼容的措施

随着电子产品趋向于小型化、智能化,电子元器件也趋向于体积更小、速度更高、集成度更大,由此带来的电磁兼容问题也日益严重.目前各类电子设备的电子元器件仍然以印制电路板(PCB)为主要装配方式.在印制电路板的电路设计阶段进行电磁兼容性设计是非常重要的,保证PCB的电磁兼容性是整个系统设计的关键.文章从元器件布局、信号走线和电源地线设计等方面,较详细地讨论了提高印制电路板的抗干扰能力及电磁兼容的措施.

The measures of improving the anti-interference capability and electromagnetic compatibility of PCB

With the evolution of the electronic product,the problem of electromagnetic compatibility(EMC) is becoming more and more severe.EMC design for printed circuit boards(PCB) can make a significant difference in the electronic product's performance.It's very important to have electromagnetism concurrent design(EMC)during the course of the PCB's circuit design.The article studies the measures of anti-interference and electromagnetic compatibility of printed circuit board from layout,track designing and power gro...
