说明：  EMC 的整改问题，相信各位接触过的工程师都会有很刻记忆。在本论坛也浏览了一些朋友对 EMC 的认识，有的朋友认为不是自己设计的电路或自己布的 PCB，那别人就对这个电源过 EMC 没有更好的方法，还有的一些朋友对电源的 IC 的功能情有独钟，他们可以分析出很多的情况。认为是这个 IC 的功能影响到了产品的 EMC 的指标。
(EMC rectification problem, I believe you will have contact with engineers is engraved memory. In this forum also browse some friends of EMC knowledge, some friends do not think of their own design circuits or own cloth PCB, this power that others will too EMC is no better way, there s some friends of power function IC s soft spot, they can analyze a lot of cases. Considered to be the function of this IC affect EMC s index products.)
