摘要: 随着人民生活水平的提高,人们对电器设备的要求也越来越高,如要求操作更便利、更美观,触摸按键作为人机交互的界面,有向大尺寸、超大尺寸发展的趋势。通过对电容式超大触摸按键的可靠性进行研究,主要包括防静电(ESD)问题、超大触摸按键的群脉冲(EFT)实验和传导抗扰度(CS)实验的抗干扰实验问题,并通过应用案例进行验证,达到了预期效果。研究结果表明:设计的超大按键防静电安装结构,能彻底解决触摸防静电问题;设计的增加抗干扰处理的软件方法,能有解决超大触摸按键在做群脉冲(EFT)实验和传导抗扰度(CS)实验时实验失效的问题。

关键词: 超大触摸按键, ESD实验, 群脉冲(EFT)实验, 传导抗扰度(CS)实验

Abstract: With the improvement of people’s living standards, people have higher and higher requirements for electrical equipment, such as more convenient operation and more beautiful. As human-equipment interaction interface, the touch button has the development trend of large size and super size. Through the research on the reliability of capacitive super large touch button, mainly including Electro-Static Discharge (ESD)problem, and the problem of anti-interference experiments of Electrical Fast Transient/burst (EFT) and RF induction conducted disturbances immunity test(CS), and through the application case, the expected effect is achieved. The research results shows that the design of the anti-static installation structure can completely solve the problem of touch; the software method of adding anti-interference processing can solve the problem of failure in EFT and CS experiment.

Key words: Super large touch button, Electro-Static Discharge(ESD), Electrical Fast Transient/burst (EFT), RF induction conducted disturbances immunity test(CS)
