【应用】基于ASIM ESD红外感应计数器整改案例：解决测试±4KV接触放电出现异常计数问题

时间： 2022-11-17 来源：ASIM 阿赛姆公众号

技术问答

本次来ASIM整改产品自动红外感应计数器，为对射电路，有发射器与接收器，当有物体挡在发射器与接收器中时，触发计数电路。测试±4KV接触放电出现异常计数。

一、整改前数据：

二、整改后数据：

三、整改方案：

1.对主板靠近塑胶外壳边做露铜处理，试空气放电点保持释放在主板大地上。

2.主板露铜用海绵顶住上方固定架金属。

3.对发射器与接收器信号线上对地并联ASIM ESD（型号：ESD3V3D005SA），测试有较小几率触发异常计数。

4.对发射器与接收器信号线上串联ASIM 磁珠（型号：CVB1005C181T），测试通过。
