ANSI/ESD S20.20 doesn’t mention hair, but the ESD Handbook ESD TR20.20 does. The general rule from ANSI/ESD S20.20 is in section 8.3. From ESD Handbook ESD TR20.20 mentions “human hair” is near the extreme end of the Triboelectric Series, so it can be high charging. But the above rule would apply; keep hair 12” away…

An excerpt from Terry Welsher’s InCompliance article titled – The “Real” Cost of ESD Damage about using “split lot” experiments to determine the effectiveness of ESD control when manufacturing electronics. “At the time of the first EOS/ESD symposium in 1979 there were few mature ESD programs, but many companies were trying to establish them. Some of…

Written by: Gene Felder, Corporate Product Manager What is the ESD control requirements for battery and pneumatic powered hand tools? From ESD Handbook ESD TR20.20 section 5.5.2.2 “Battery powered and pneumatic hand tools while being held should have a resistance to ground of less than 1 x 10E12 ohms.” If tool’s housing is conductive or…

ElectroStatic Discharge (ESD) is the hidden enemy within your factory. You cannot feel or see most ESD events but they can cause electronic components to fail or cause mysterious and annoying problems. There are two types of ESD damage: 1) Catastrophic failures, and 2) Latent defects. By definition, normal quality control inspections are able to…
