Treston - ESD workspaces Watch this video: ESD workstation management https://vimeo.com/657013937 In ordinary movement a person creates static electricity. In these circumstances hand contact with a conductive material will discharge static from the body very rapidly. This is ESD = Electrostatic discharge. Static electricity has become a major problem in the electronics industry. Usually this passes unnoticed because our bodies do not feel discharges below 3000 volts. We may see ESD above 5000 volts as a spark. The most sensitive components may be damaged by a charge of just 30 volts, and many standard components ESD - Electrostatic discharge CHARGES GENERATED ON DAILY WORK ACTIVITIES Walking across a carpet 1 500 – 35 000 volts Walking over vinyl floor 250 – 12 000 volts Working at a bench 700 – 6 000 volts Picking up a plastic bag from bench 1 200 – 20 000 volts Chair with polyurethane foam 400 - 3 000 volts are sensitive to charges of 100...200 volts. The presence of inherent ESD is not easy to detect. Product-related defects can often be latent and become active over time. An unbroken ESD safety chain is essential to guarantee the quality of the final product. An ESD-protected production chain is called an EPA (= ESD Protected Area). Employees must be able to implement the right policies in an ESDprotected work environment. The lower the relative humidity the higher the voltage. The lowest values in the table usually apply when the relative humidity is 65-90%. During a cold winter day, the relative humidity in indoor spaces can be as low as 10 %.
