The harm caused by static electricity in industrial production can be mainly attributed to the following two mechanisms:
One: The hazards caused by electrostatic discharge (ESD):
(1) Cause malfunction or malfunction of electronic equipment and cause electromagnetic interference.
(2) Break down integrated circuits and precision electronic components, or promote the aging of components and reduce the production yield.
(3) High-voltage electrostatic discharge causes electric shock, endangering personal safety.
(4) It is very easy to cause explosion and fire in the production site of many flammable and explosive products or dust and oil mist.
Second, the harm caused by electrostatic attraction (ESA):
(1) Electronics industry: Absorb dust, causing pollution of integrated circuits and semiconductor components, greatly reducing the yield.
(2) Film and plastics industry: Films or films are unevenly wound; film and CD plastic discs are contaminated with dust, which affects quality.
(3) Papermaking and printing industry: uneven paper winding, inaccurate overprinting, serious dirt absorption, and even paper sticking, affecting production.
(4) Textile industry: Causes the roots to flutter, torn flowers and ends, and yarn tangles.
(5) Plastic spraying: Plastic products have high static electricity and are easy to attract dust. After spraying, they affect the appearance and quality of the workpiece.
The breakdown damage of components caused by electrostatic discharge is the most common and serious electrostatic hazard in the electronics industry. It is divided into hard breakdown and soft breakdown. Hard breakdown is a one-time cause of dielectric breakdown, burnout or permanent failure of components; soft breakdown is the degradation of device performance or the reduction of parameter indicators. Friction and electricity and human static electricity are two major hazards in the electronics and microelectronics industries. Source, but the generation of static electricity is not a hazard. The hazard lies in the accumulation of static electricity and the resulting electrostatic discharge, so it must be controlled.
