The New Footwear/Flooring Systems Requirements of ANSI/ESD S20.20-2014
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…

Fundamental ESD Control Principles – Personnel Grounding
A fundamental principle of ESD control is to ground conductors including people at ESD protected workstations. Wrist straps are the first line of defense against ESD, the most common personnel grounding device used, and are required to be used if the operator is sitting. The wristband should be worn snug to the skin with its…

Operator’s Part in ESD Control
Think Of Static Electricity as Germs and Contamination! Daily life has other examples of hidden enemies where careful procedures must be followed to regularly obtain positive results. One example is sterilization, which combats germs and contamination in hospitals. Damage caused by invisible and undetectable events can be understood by comparing ESD damage to medical contamination of the human…
What is OHM’s Law?
At this point in our blog series concerning ESD Awareness, we should consider some basic physics: Ohm’s law is an extremely useful equation in the field of electrical/electronic engineering because it describes how voltage, current, and resistance are interrelated. Ohm’s law states that, in an electrical circuit, the current passing through a conductor between two…
ESD Awareness Symbols Explained
There are three ESD Awareness Symbols defined in ANSI/ESD S8.1: ESD Susceptibility Symbol ESD Protective Symbol ESD Common Point Ground To view information about each symbol please click the link or image above. Desco provides downloadable symbol artwork at no charge: ESD Susceptibility Symbol ESD Protective Symbol ESD Common Point Ground Desco utilizes the proper […]
Types Of ESD Device Damage
ESD damage is not always visible to the naked eye. ESD damage to electronic components can be: catastrophic and latent. Catastrophic failure causes a failure in an ESD sensitive item that is permanent. The ESD event may have caused a metal melt, junction breakdown or oxide failure. Normal inspection is able to detect a catastrophic failure. A latent…
ElectroStatic Charges vs Electrostatic Discharges (ESD)
ElectroStatic charges and ElectroStatic discharges are different. All material can tribocharge (generate ElectroStatic charges). This is static electricity which is an electrical charge at rest. When an electrical charge is not at rest, but discharges (i.e. ESD), problems can occur. All matter is constructed from atoms which have negatively charged electrons circling the atom’s nucleus…
