ANSI/ESD S20.20 now requires the Operator Walking Test (ANSI/ESD STM97.1) and conformance to Operator Resistance Measurements (ANSI/ESD STM97.2) for product qualification of flooring / footwear systems for grounding personnel. What is the importance of the Walking Test? It is necessary to qualify the Footwear / Flooring personnel grounding system for certification to ANSI/ESD S20.20. It…

Measure: Indicate surface voltage and polarity of objects. Control: Insulators must be identified at an ESD work area and must meet the guidelines in the ESDA’s ESD Control Program Handbook-ESD TR20.20. Non-Process Essential Insulators If items that can charge to 125 volts or more*, then one of the following will be used: Remove the item…

 Most people notice a difference in the ability to generate static electricity when the air gets dryer (the % RH decreases). As an example, walking across a carpet can yield a charge of 35kV at 10% RH [very dry air], but will drop significantly to 7.5kV at 55% RH. In an electronics manufacturing environment lower…

Question: 1) In the scope, 200 volts CDM & 35 volts on isolated conductors are added. What is the intention to add them? Why are both of them determined on the value of 200 volts and 35 volts, respectively?  Question: 2) As defined in clause 8.3.1, “If the field measured on the process required insulator…
