建立合理的静电放电模型是进行静电防护的前提,为了有效改善移动终端的防静电性能,在现有的人体模型的基础上,根据静电放电会产生高电压、高电流和强烈的电磁辐射的特点,建立了移动终端静电放电的电磁辐射模型、移动终端模型、人体-移动终端模型。对各模型进行理论推导和仿真分析可知,电磁场的辐射频率对移动终端会产生串扰、辐射功率对终端的影响相对较小;增大终端输入电阻、人体和终端的接触电阻、以及人体和终端的接触电感,减小终端输入电容、人体和终端的接触电容等,都可以减少静电放电对终端造成的损伤。
In order to effectively improve the anti-static performance of the mobile terminal, a reasonable electrostatic discharge model is prerequisite for electrostatic protection. Based on the current human body model, high voltage, high current and strong electromagnetic radiation are generated according to the electrostatic discharge , Established the electromagnetic radiation model of mobile terminal electrostatic discharge, mobile terminal model, human-mobile terminal model. The theoretical derivation and simulation analysis of each model shows that the radiation frequency of the electromagnetic field will cause crosstalk to the mobile terminal, and the radiation power has a relatively small impact on the terminal; increasing the input resistance of the terminal, the contact resistance between the human body and the terminal, Contact inductance, reduce the terminal input capacitance, the body and the terminal contact capacitance, etc., can reduce the electrostatic discharge damage to the terminal.
