Discharge, also Known as electrostatic discharge or ESD, results from the release of electrons from a static charge that can build up within insulation. Numerous modern electronics are extremely sensitive to ESD due to their very thin layer of insulating glass which could get damaged when subjected to as little as 40V of release or less. Electrostatic discharge was documented as a substantial contributor to serious problems which range from pc freeze-ups and dropped phone calls to failures of semiconductors and shutdowns of mission critical operations. The need to manufacture integrated elements that use less electricity and enhance circuit design and functionality will continue to create important challenges for designers to reanalyze conventional building materials, and layout inactive free surroundings and stringent static control processes so static discharge cannot become an issue in the first location.
Electrostatic dissipative flooring is recommended for use in electronic assembly and test areas, flammable storage and processing, and munitions areas. There are several terms that are sometimes used erroneously by sellers to describe static control flooring. Conductive flooring is not the exact same thing as static dissipative flooring. Conductive flooring is flooring that has low BVG body voltage generation readings, offering high levels of protection to your products whereas static dissipative flooring products are designed for use where static discharge control is necessary, but the immunity level of the flooring does not have to be as low as that supplied by conductive flooring. Likewise the expression antistatic flooring differs as it helps eliminate static electricity by providing a controlled low immunity. An antistatic floor dissipates charges from parts you are working on as you put them on the ground. If conductive flooring also exhibits antistatic properties, it will often meet or surpass any static control requirement for body voltage generation.
The Vast Majority of ESD Flooring failures that happen are due to elevated moisture and alkalinity levels in the substrate. Moisture levels should be no greater than 3 pounds per 1000 square feet per 24 hours. Moisture problems can be found easily by pulling samples and performing ASTM moisture evaluations. ASTM-F-1869 – Standard Test Method for Measuring Moisture Vapor Rate of Concrete Subfloor Using Anhydrous Calcium Chloride the maximum allowed transmission speed is 3 pounds per 1000 square feet and ASTM F-2170 – Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in Sutu Probes the highest relative humidity must be below 80 can be used to measure moisture vapor speed and relative humidity of a concrete york flooring subfloor respectively. Compounds and alkalinity problems can be prevented by filling the cracks prior to installation, leveling and patching the sub-floor, and installing vapor barriers.
