Dear colleagues, I would like to ask you about ESD standard. I would like to know what is difference between ANSI/ESD S20.20 and EN 61340. Which standard we should use? Thank you very much for your answer. Mekmat

It depends on where your facility is located: * United States use ANSI/ESD S20.20 * Eurolanders use IEC 61340 * UK use BS EN 61340

Properly grounding employees and work surfaces is the single most effective method of reducing esd damage to parts. Tell us about your ESD control program and how well it conforms to ANSI/ESD S20.20-1999, Electrostatic Discharge Control Program Stan

Ashok: Hey guy ... snow starting to melt yet? Keeping process insultaors with a charge of over 2kv a foot from ESDS items seems reasonable. The HBM assumes contact with the item, so it should have a lower potential. You should double check with E

The auditor may be using "verify" in an ESD Program context. See ANSI/ESD S20.20 [1999], 6.1.3, Compliance Verification Plan. It gives one definition of what the auditor may be seeking. For more on verification programs, look here: http://www.protek

Guys: Folk at EOSEAD told me two things on this: 1 Yes "All process essential insulators that have electrostatic fields that exceed 2000 volts should be kept at a minimum distance of 12 inches from ESDS items." is correct. 2 The latest revision to

Lower RH = more static build-up on production floor = greater chance of ESD damage to product. Primarily, I think your SMT print job can be affected by RH which could cause defects like the ones you mention. Look at ANSI/ESD S20.20 for more info an

Hi all, We have been trying to improve our current levels of ESD control in our SMT manufacturing area, while carrying out a initial audit I have found that we have two different grounding planes. One for the electrical grounding through mains powe
