摘要
为保证电路性能,在进行印制电路板(PCB)设计时应考虑抗干扰性,这对于减小系统电磁信息辐射具有重要的意义。本文着重讨论按元器件的布局及布线原则以最大限度地提高电路的性能指标,达到抗干扰的设计目的。同时也说明了如何通过减小串扰来使电子器件性能最优化。分析了影响PCB抗干扰性能的几个不同因素,说明了PCB制作过程中应采取的解决办法。
In order to ensure the circuit performance, its anti-interference must be considered when design PCB, which have an important significance on reducing the system of electromagnetism information radiation. This paper focuses on how to improve the circuit performance indicators according to the principles of the layout of components and wirings to achieve anti-jamming, which simultaneously explained how to reduce the crosstalk to ensure the electronic device performance optimization. In the paper we analysis several different factors of affecting PCB anti-interference and introduce some solutions in the PCB manufacture processing.
