Grounding operators that handle ESD susceptible devices is one of the requirements for an ESD Control Plan. In fact, it is the basis of the ESD Association’s ANSI/ESD S20.20-2014 Standard. Grounding the body and maintaining maximum resistance to ground (Rtg) of less than 35 megohms prevents the operator from generating more than 100 volts. The…
This is the type of conversation we often have with companies about the handling of Class 0 (Zero) ESD devices. The purpose of this blog post is to shed some light on the topic and answer some common questions with regards to Class 0 Devices. What does the word “Class” signify? The word Class is…

Insulators and Isolated Conductors Wrist straps and work surface mats are some of the most common devices used to remove static charges. Wrist straps drain charges from operators and a properly grounded mat will provide path-to-ground for for exposed ESD susceptible devices . However, what if the static charge in question is on something…

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…

The 2007 version of the ANSI/ESD S20.20 has been updated. The ESDA continues to remove guidance from the ANSI/ESD S20.20 and focus the document on the requirements for an ESD Control Plan. Guidance for how to meet requirements of the ANSI/ESD S20.20 and how to mange the ESD Control Plan is detailed in the ESD Handbook-…
