ESD Sensitive Device

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…

Antistatic is the ESD control property properly referred to as “low charging”. This is an important property for all bags used inside or outside of an ESD protected area (EPA). Specifically, it is important that the inside of the bag be low charging, so when the ESD Sensitive Device is inserted into the bag or…

A Faraday cage or Faraday shield is an enclosure formed by conducting material or by a mesh of such material. Such an enclosure blocks external static and non-static electric fields. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836. An impressive demonstration of the Faraday cage effect is that…
