Webrealistic ESD threshold or level of immunity, for a system or part in the real world? While the human body ESD waveform has been a topic of research for many years, studies by Hyatt and Mellburg, "Bringing ESD Testing Into The 20th Century" [3]; Mellberg, Sanesi, and Hish, "Recent Developments In ESD Waveform Evaluation" [4]; and Fisher, "A Severe WebThe logical reference potential is ESD ground. So, the first and most important rule in avoiding ESD damage is to keep ICs and everything that comes in close proximity to them at ESD ground potential. Four supplementary rules support this first rule: • Any person handling ICs must be grounded either with a wrist strap or ESD protective ... linux ubuntu kostenlos
