摘要
静电放电(ESD)抗扰度性能已成为衡量电子产品性能的一项重要指标.针对某一型号的称重控制器提出了一种用于提高该被测设备静电放电抗扰度性能的新方法.针对称重控制器的结构,分析其因不良的架构导致静电放电的原因,通过铜带线改良其连接,使其成为一个紧密整体,并分别对于液晶显示部分和内壳结构进行改进.实验结果表明被测物体可顺利通过测试,证明了该方法的有效性.
Electrostatic Discharge（ESD） immunity test is a test of required electromagnetic interference（EMS） project of many electronic products.The weighing controller failed to pass the test,and it is too complicated to modify the circuit with large-scale.This paper presents a new idea of electrostatic discharge improvement.By analyzing its structure,it is deduced that electrostatic discharge due to the poor structure,improves the structure of EUT by using flat type copper wire,then improves the liquid crystal display part and the inner shell structure respectively.The test result shows that the equipment succeeded in passing the test,which proved that the method is effective,and it offers some reference value when some circuits are too complex to modify.
