静电放电已经逐渐成为导致各类电子设备故障的主要原因之一,在电子产品研制过程中通常采用实物测试方式检验产品抗静电能力,但该方式耗费资金过大、可重复性差同时易损伤受试设备。在这种情况下,建立基于三维场路协同方法的静电损伤仿真测试平台有效地解决了上述问题。该平台以电脑仿真技术(CST)软件为基础,通过构建静电放电枪模块,结合受试设备模块和仿真参数设置模块,以时域有限积分法求解器进行仿真,并利用数据输出和处理模块得出结果。利用建立好的仿真测试平台对一台数据传输设备进行8 k V接触放电,观察其表面电流和磁场分布,并对其造成的传导干扰和辐射干扰进行分析。通过建立静电损伤仿真测试平台,实现了静电放电测试的可重复以及无损伤的目的,具有较强的工程指导意义。
Electrostatic discharge has gradually become one of the main causes of various types of electronic equipment failure. In the process of electronic product development, the physical test method is usually used to test the antistatic capability of the product. However, this method consumes too much money and has poor repeatability, equipment. In this case, the establishment of electrostatic discharge simulation test platform based on the synergetic three-dimensional field circuit effectively solves the above problems. Based on the CST software, the platform is constructed by the electrostatic discharge gun module, the test equipment module and the simulation parameter setting module, and the finite-integral time-domain solver is used for simulation. The data output and processing module The results. Using a built-in simulation test platform, a data transmission device is subjected to 8 kV contact discharge to observe its surface current and magnetic field distribution, and to analyze the conducted interference and radiated interference caused by it. Through the establishment of electrostatic damage simulation test platform to achieve the ESD test repeated and non-destructive purposes, with strong engineering guidance.
