讲师介绍：

马永健老师：马永健，高级工程师，深圳兰博滤波科技有限公司首席EMC专家。电子技术标准化研究所特聘EMC讲师，中国高科技产业研究会特聘EMC讲师，《电子元器件网》、《我爱方案网》特聘EMC专家，中国高科技产业研究会高级会员，中国电子学会高级会员，江西宜春学院客座教授。

课程介绍：

EMC屏蔽不是机械/结构工程师的独有技术，是普通老百姓都应该了解的电磁屏蔽技术，是全体产品研发工程师必需了解的EMC技术。

高速发展的电子信息技术给人们带来了高效和便利的生活，但产生的电磁辐射却带来日益严重的电磁干扰（简称EMI）问题，成为威胁健康的又一新污染源。据英国国家辐射保护委员会调查报告，高压线产生的电磁辐射影响下，儿童白血病发病率较正常区域的高出一倍。电磁辐射会降低甚至破坏人体的生命支持系统功能，引发各种疾病。

EMI也会使电子系统障碍，破坏设备运行，造成严重经济损失。若遭受电磁武器的强力冲击，军事机密有被窃取风险，设备信息系统也会暂时性失灵或永久性损坏，严重危害国防安全。

要解决EMI问题，EMC领域有三大技术，但只有EMC屏蔽是老百姓可以部分掌握的一个EMC技术。也是所有产品开发工程师最容易理解和掌握的一门EMC技术。

本课程运用通俗易懂的语言，结合插图和案例，由浅入深地介绍EMC屏蔽的相关知识节点。

介绍消除EMI对人类生活有影响的相关国家标准；阐述是否有辐射或电磁波的简便的测试方法及其应该采取的一些措施；阐明抑制高压电EMI所必须具备的安全距离；明晰抑制EMI的EMC屏蔽三种方式；强调使用EMC屏蔽材料解决EMI问题的注意事项。

课程要点:

远离骚扰源是解决EMI问题的最省力省钱的方法。

只要满足产品可靠性指标要求，任意厚度的任何金属材料都能满足EMC屏蔽要求。

等电位体是最有效地解决EMI问题的屏蔽形体。
