The electrostatic damage to the manufacturing industry

Views: 296 Author: Site Editor Publish Time: Origin: Site

The damage caused by static electricity in industrial production can be mainly attributed to the following two mechanisms:
1、 Hazards caused by electrostatic discharge (ESD)

(1) Causing malfunction or malfunction of electronic equipment, resulting in electromagnetic interference.

(2) Breakdown of integrated circuits and precision electronic components, or promotion of component aging, reducing production yield.

(3) High voltage electrostatic discharge causes electric shock and endangers personal safety.

(4) Explosion and fire are highly likely to occur in production sites with high levels of flammable and explosive materials, dust, and oil mist.

2、 Hazards caused by electrostatic attraction (ESA)

(1) Electronic industry: adsorbing dust, causing pollution of integrated circuits and semiconductor components, greatly reducing yield.

(2) Film and plastic industry: causing uneven winding of film or film; The film and CD plastic disc are contaminated with dust, which affects the quality.

(3) The papermaking and printing industry: The paper is not rolled neatly, the overprinting is not accurate, the dirt absorption is severe, and even the paper is stuck, affecting production.

(4) Textile manufacturing: it causes the root silk to float, tangle and break ends, yarn entanglement and other hazards.
(5) Plastic spraying: Plastic products have high static electricity and are prone to dust adsorption, which affects the aesthetics and quality of the workpiece after spraying.

The breakdown damage of components caused by electrostatic discharge is the most common and serious electrostatic hazard in the electronic industry, which is divided into hard breakdown and soft breakdown. Hard breakdown refers to the one-time occurrence of component dielectric breakdown, burning, or permanent failure; Soft breakdown refers to the deterioration of device performance or the decrease of parameter indicators. Friction electrification and human static electricity are two major sources of damage in the electronic and microelectronic industries.
