摘要

针对静电放电(ESD)抗扰度测试中存在的重复性问题,本文利用建立的ESD模拟测试系统,实验研究了接触式放电和非接触式放电(又称空气式静电放电)两种放电模式下放电参数,比如放电电流、上升时间、半圆环天线上的耦合电压等随放电电压的变化关系。研究得出,接触式放电模式下,放电参数与放电电压呈很好的线性关系,放电参数随着放电电压的增大呈增大趋势,基于这种线性关系建立了ESD模拟器的严酷度模型;非接触式放电模式下,放电参数与放电电压关系复杂,当放电电压较低时,放电电流和耦合电压随着放电电压的增大呈增大趋势,上升时间最初基本保持不变,随后也呈现增大趋势,当放电电压增大到一定值时,随着放电电压的进一步增大,放电参数呈现下降趋势。
To the reproducibility problem in the electrostatic discharge(ESD)immunity test,in this paper,using the ESD simulating testing system,the influence of charged voltage on ESD parameters,e.g.,discharge current,rise time and induced voltage in a semicircular loop antenna are studied under two discharge modes:contact discharge method and air discharge method.It is concluded that,under contact discharge mode,ESD parameters are good linearly proportional to the charge voltage,and the ESD parameters increase with the increasing charge voltage.Basing on this linearly relationship,a severity model for ESD generator is established.When the discharge mode is air discharge method,the relationship between ESD parameters and charge voltage is rather complex,under lower charge voltage,the discharge current and induced voltage increase with increasing voltage,rise time changes few firstly,and then increase with increasing voltage.As the charge voltage increases to a certain value,the ESD parameters decrease with increasing voltage.
