ESD Shoes: The Importance of Electrostatic Dissipative Footwear in the Workplace

Electrostatic discharge (ESD) can be a major concern in many industries, particularly those that involve electronics manufacturing, semiconductor production, and pharmaceuticals. When people move around, they generate static electricity, which can cause electrical charges to build up on their clothing and footwear. These charges can cause damage to sensitive electronic components, leading to significant losses […]

All the ESD Static Control Terms You Need to Know

Air ion Groups of about 10 molecules (water, impurities, etc.), bound by polarisation forces into individually charged oxygen or nitrogen molecules.   Air Ionizer Electrically charged source of air molecules (ions).   Antistat, agent A substance applied partially or partially to a material so that the surface is dissipative to static electricity or less sensitive […]

What is Class 100 Nitrile Glove

The Class 100 workshop is called Class 100 because of its cleanliness, the number of particles with a particle size greater than or equal to 0.1 microns cannot be greater than 100. The concept that there can be no more than 100 dusts of 0.1 microns in the workshop is what it is all about. […]

Hand Tools, Equipment, and Fixtures

Only ESDP hand tools should be used in the EPA. Manufacturer recommendations for usage and cleaning shall be followed. Component holding trays, microscopes, and other devices or fixtures commonly found in an EPA shall be constructed of metal or permanent static dissipative plastic and shall be maintained at ground potential by placing them on a […]

Relative Humidity Control & Air Ionizers

Relative Humidity Control Humidity control is important for an effective ESD program for two primary reasons; At lower humidity levels (< 30% RH), the dissipation of commonly generated static charges does not take place, thus adding to the probability of ESD events. Materials (such as pink poly) rely on the moisture in the air to […]

Equipment and Facilities Grounding

All permanent and semi-permanent metallic structures and test equipment utilized during handling or manufacturing of ESDS components or hardware shall be grounded using a common point ground. A major goal of this document is to ensure that all conductive materials are tied together at the same potential. An equal potential workstation is the secret to […]

Personnel Grounding Devices

Personnel grounding devices are the primary means of ESD control. For static charges generated during ordinary body movements, personnel-grounding devices provide a permanent path to ground. Such devices may take various forms such as: Wrist Straps Leg Straps Heel Straps Conductive Shoes Wrist Straps Wrist straps are considered to be the first line of defense […]

ESD Protective Floor Mats and Conductive Floors

Conductive floors or grounded conductive floor mats are mandatory in any EPA where personnel handling ESDS items are not wearing wrist straps. Under these circumstances, personnel shall use leg straps, heel straps, or conductive shoes. ESDP flooring or floor mats shall be used in all Class 1 facilities. The proper cleaning and maintenance of a […]

ESD Protective Work Surfaces

The ESDP work surface (Reference ESD TR20.20-2008, section 5.3.1 – Work surfaces) will provide a safe path to ground for static charges within the operator’s general working area. Either the ESDP work surface may be fabricated as a part of the workbench or it may be a separate addon item. In either case, the ESDP […]
