LarryP, ESD smocks in combination with a wrist strap provide a path to ground for any charge potential. An operator wearing a smock while grounded will provide a path to ground for the chair. With an ESD chair you can have antistatic or static

It would, but is it correct? This is what QA came back with. "Think of a chassis, connected to earth ground, sitting on top of a mat. In this situation, we are bypassing the meg-ohm resistor to ground." If the mat, the operator and the test equipmen

Smtnetters One more question on ESD Control program. Does anyone ground there power equipments and how ? e.g., Pneumatic torque tools , electric screwdrivers, hand soldering stations, solder pots etc. I am not sure about pneumatic hand tools , howev

Ashok: Our procedure allows connecting a resistor of less than 1 Mohm between the mat and ground, if safety codes and/or other authorities require inclusion of a series resistor (to eliminate the safety hazard of touching a high voltage circuit with

Currently in our facility we store used and discarded flux residues from the wave solder machines in 50 gallon drums. These drums are picked up and disposed of by an outside contractor. During a recent audit we were cited for not having the drums pr

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

I need some help in setting straight QA which owns our ESD Procedures. 1. Is the limmiting resistor for personel safety or to slow down ESD discharge? Everything I have read indicates it is for personnel safety. 2. Is it an ESD violation to have

How are you going to ground the metal sheets? You certainly don't want to leave these hard grounded; you need to dissipate any static charge over time.

This was a citation issued during an internal audit. I believe that it was besed solely from company policy. I am hot even sure that grounding is an industry standard although OSHA does have some ducumentation pertaining to grounding of flameable was

Hi, 1) Was reading the links provided by Dave F, under the thread "waste" which was about the ESD grounding of drums. 2) thanks to Dave F, now have "back-bone" refer sources to explain ESD terms to those who ask and seek to better understand this n
