【应用】莱尔德板级屏蔽罩BMI-S-210-C用于LCD驱动板接口处信号屏蔽，解决EMI测试超标问题

时间： 2022-05-27 来源：世强

技术问答

随着电力电子技术日益向高频率、高速度、高灵敏度的方向发展，电力、电子设备的发射功率越来越大，灵敏度越来越高，接受微弱信号的能力越来越强。电磁兼容已成为当今世界电气工业的热点问题，随之而来的就是电磁干扰，成为了电气电子设备及其构成的系统正常工作的突出障碍。

现一显示屏驱动器项目，客户做的LCD驱动板，其中LCD接口信号和对Flash读取的信号频率较高，主要是MCU和Flash之间有信号干扰，在EMI测试时，30～200MHz都有干扰。因此客户需要屏蔽材料来屏蔽电磁干扰。

针对上述客户的问题，推荐LAIRD的板级屏蔽罩 BMI-S-210-C，该屏蔽罩封装尺寸44.6mm x 31.1mm x 2.4mm，尺寸满足客户的需求。该屏蔽罩使用0.2mm的冷轧钢材料，具有良好的硬度，使得屏蔽罩不易变形，且维修方便。屏蔽罩使用雾锡为镀层，可焊性良好、导电性好、耐腐蚀能力强。并且具有良好的屏蔽效果，可以有效的防止其他器件的干扰。

如下是Laird板级屏蔽罩BMI-S-210-C的一技术参数，可供查阅。

Laird Eccosorb™ 吸波材料具有较高介电常数和高磁导率特性，是Retime和ASIC芯片“最佳”吸波解决方案

抑制Retimer芯片在22GHz的杂讯是一回事，准确提供所需解决方案的理想特征参数又是另外一回事。本文介绍一家全球网络技术制造商如何在对比九种不同的仿真结果后，最终选择Laird™ Eccosorb™ GDS（经过莱尔德实验室确认的高频吸波材料，可降低总辐射功率）作为其理想的解决方案。
