PROPER GROUNDING OF THE "OBJECT" PCBA BOARD: You cannot ground an insulator. Insulators accumulate a charge, but the charge must be neutralized, usually by ionization. We only use ionizers at tape stations and bins where travelers and other paper are collected.
Bottom line: Use a field meter to determine where you need to use ionizers.
PROPER GROUNDING OF PEOPLE: The moisture on the surface of people makes people conductors. They accumulate charge because they move and are insulated from ground. So, a wrist strap properly connected to ground is the proper way to dissipate charges on people. People generate huge charges by fidgeting in their chair and other common movements. For instance:
||Electrostatic voltage (v) Static generation process||at 10 to 20% RH||at 65 to 95% RH Walking on carpet||35,000||1,500 Walking on vinyl flooring||12,000||250 Worker sitting at a work bench||6,000||700 Handling a vinyl envelope used for work instructions||7,000||600 Picking-up a sandwich plastic bag from a bench||20,000||1,200 Sitting at polyurethane cushioned bench||18,000||1,500
Comments are: * How do you currently �properly �bond/ground� the static electricity between the PCBA board to the earth grounding source�? * So continuing with your line of thought, if someone is not grounded and generates 6kv while sitting at their bench, and picks-up a board and touches the trace leading to a component that is sensitive to
