深圳电子产品质量检测中心 邓志新 李思雄

摘 要 文章主要介绍EMI快速诊断与对策，指出EMI改进的关键是EMI问题诊断， 解决电磁兼容问题的根本办法，是进行电磁 兼容设计。EMI设计核心是紧紧围绕降低骚扰源频率f和减小高频电流环面积两大措施。文章倡导人性化工作态度，作者认 为，只要不断的学习和总结，EMC是逐渐“看得见和摸得着”的，是有规可循的。 关键词 认证 EMI 规律 诊断 对策 设计

Abstract In this article, EMI fast diagnosis and countermeasure is introduced. EMI diagnosis is the key of EMI improvement, EMC design is the fundamentals of solving EMC problem. The core of EMC design is to take two measures-to reduce EMI source frequency and to reduce the acreage of high frequency current loop . Author sparkplug humanistic attitude to EMC,and author think that EMC will come into view and can be found out，a rule shall be there to be useable. Keywords certification, EMI, rule, di
