摘要
PCB印制电路板的设计质量不仅直接影响到电子产品的可靠性和稳定性,甚至是电子产品设计成败的关键.随着电子技术的发展,电子产品趋向于小型化、智能化、集成化,由此带来的电磁兼容问题也日益严重.因为PCB印刷电路板的密度越来越高,电磁兼容性EMC设计至关重要.因此,在设绘印制板图时,除了要为电路中的元器件提供正确无误的电气连接外,还应充分考虑印制板的抗干扰问题.本文分析了电磁干扰的产生机理和原因,并提出了有效抑制和防止电磁干扰的措施和方法.
The quality of printed circuit board（PCB） has a direct impact on the reliability and stability of electronic products.It is the key of electronic product design.With the development of electronic technology,electronic products tend to be miniaturized,intelligentized and integrated.Hence the electromagnetic compatibility（EMC） problem has become increasingly severe.The accurate connection of components and the interference immunity of PCB have been considered in the design.In this paper,the mechanism of electromagnetic interference was analyzed,and an effective suppression and prevention method of electromagnetic interference was proposed.
