【成功案例】CHO-SORB EMI衰减器成功解决产品辐射发射，通过KC认证
对于产品工程师而言，EMI是个绕不过去的话题。尤其对于出口的电子产品，EMI的测试会更严格。EMI不达标，除了会导致自身产品系统故障，也会干扰其他设备的正常运行，同时也会影响保密数据的安全性。最近，我们做了一款要通过韩国KC认证的空气净化器产品，前后折腾了3个月，换了3家EMC实验室，都是一样的辐射超标。最后用了PARKER CHOMERICS的CHO-SORB EMI衰减器，才终于通过KC认证，并把裕量控制在-6dB以内，产品才顺利满足客户要求。见Fig 1。
Fig 1 使用CHO-SORB EMI衰减器后得辐射发射曲线
一般空气净化器上，都会外接很多传感器，比如PM2.5传感器, 异味VOC, 温湿度传感器，甲醛传感器，负离子发生器，还有控制空气内外循环的大的电机等。我们的机器，除了上面这些，还外接了触摸按键，WIFI等无线信号。每个传感器都是通过很长的信号线连接，而电机和高压负离子发生器，又是通过高压板来控制，所以，电源传到辐射和RF射频辐射，都是一个很严峻的挑战。Fig 2是最初系统设计框图：
Fig 2 空气净化器设计框图， 未加EMI 衰减器
当这些传感器和电机，负离子同时工作时，会看到辐射发射部分超标很厉害。在EMC实验室里，我们先做了1m的辐射发射，又做了3m的辐射发射，在信号线和电源线没有增加EMI衰减器前，辐射在很多频率点都超过了标准要求。 见Fig 3
Fig 3 未加EMI 衰减器之前的辐射发射曲线
曲线超标后，一般都是根据超标的频率点进行分析。分析下来，基本都属于共模干扰。我们尝试了4种方案：
第一种： 从电路板入手，在CPU、晶振和高速内存部分，增加屏蔽罩。这种对于高频辐射，非常有用，尤其是1GHz以上的。但是我们目前的辐射超标部分，都是1GHz以内，对于低频辐射发射超标，没有大的改善。
第二种，修改电路板，在CLK和数据信号线上串电阻和磁珠，在电源线上串磁珠。这种通过增加插入损耗来衰减的方式，对于40MHz的频率点有改善，但是对于40MHz以上的，基本没有作用。辐射问题还是没解决。见Fig 4
Fig 4 信号线和CLK增加串行电阻和磁珠后的曲线
第3种，使用实验室提供的各种大小规格不同的磁环和磁扣， 由于不知道具体规格和参数，加上去后，曲线变的时好时坏，不具有一致性。也不具有可生产性。不过，为我们解决问题指引了方向。
第4种，使用CHO-SORB的有明确衰减性能说明的衰减器。CHO-SORB的EMI衰减器，见Fig 5使用特殊形式的软铁氧磁体材料（由镍和锌为主复合成的金属氧化物），主要用了衰减辐射发射。它有2大特性： 高磁导率，用来聚集磁场；高电阻率，用来限制回流电路中的电流幅度。从它的特性曲线 Fig 6来看， 它对低频和直流的影响不大，对于30MHz~200MHz内的高频，抑制效果最明显。
Fig 5 CHO-SORB EMI衰减器 Fig 6 环形和套管型特性阻抗曲线
由于不同孔径的阻抗特性不一样，我们根据EMC实验室仪器上标出的超标频率，见Table-1, 和实际用的线的宽度和厚度，选择对应孔径的EMI衰减器型号。
Table-1 超标频率点
根据实际情况，我们选择了 83-10-M12773-1000和83-10-M673-1000的环形衰减器用在信号线上，83-10-M12817-1000的环形分开式衰减器，用在电源线上和电机线上以及负离子线上。加EMI衰减器后的框图见Fig 7.
Fig 7 增减EMI 衰减器的设计框图
为了比较效果，我们对PM2.5的电源和数据线作了加衰减器和不加的对比，能明显看出差异。Fig 8 是PM2.5的先没有加衰减器的曲线，有3处超标。
Fig 9是PM2.5加了衰减器的测试曲线。还剩一个频点超标（其他线引起的）。
通过EMC实验室实际对比测试，CHO-SORB能快速，有效的抑制RF辐射发射, 效果比较明显。对于想要通过各种产品认证的设计人员来说，是不错的选择。
注意事项：
1. 要根据实际的超标频率点，电源和信号线的大小来选择对应衰减器的规格。在选择最大阻抗的衰减器管时，有2个经验:
(a) 选择形状后，越长的衰减器效果比越宽的衰减器效果好。
(b) 在已选择的衰减器中，线绕的圈数越多，效果越好。
2. 线上套衰减器，对传送的差模信号没有影响，对共模电流的抑制比较明显。
3. 衰减器放入电路中，也在源和负载之间工作，只有源和负载阻抗很低时，才有可能从简单的分压电路中获得最大衰减。
4. 很少有铁氧磁体的阻抗可以超过2~300欧这个范围，所以，加载开路线上的衰减器所能带来的衰减的典型值为6~10dB; 特殊情况下，当连接线表现为低阻抗时，还可以获得20dB的衰减。

FENT Lv8. 研究员 2019-06-17现在国内产品确实是精简成本，不考虑EMC认证，前几天一个产品客户自己配套电风扇，风扇运行后电路马上不能工作了！国人为了生意，各种精简成本啊！

【经验】专为吸波应用设计的屏蔽材料CHO-MUTE™、CHO-SORB®，可提供高效可靠的屏蔽应用方案
在EMI屏蔽应用中，除了常见的导电屏蔽材料以外，我们还经常会听到另一种材料的应用，那就是吸波材料。这种材料是通过将EMI电磁波的能量转化为热能，从而实现衰减EMI干扰的效果。本文具体介绍了吸波材料的EMI屏蔽原理，以及应用分类。并且推荐了派克固美丽公司生产的两款吸波材料CHO-MUTETM和CHO-SORB®系列，分别在近端宽带吸波方案和近源窄带吸波方案中的典型应用实例。
