What are the methods of anti-static

When the weather is dry, static electricity is more likely to be generated, and in certain situations, the impact and harm caused by static electricity are also very large. If you want to prevent static electricity, you can choose anti-static shoes, or use static electricity elimination equipment to help prevent static electricity.

1. Grounding

Grounding is very important to reduce the static charge generated on conductors. The human body is a conductor and the main source of static electricity. Therefore, we must reduce the amount of static charge that is generated on people who come into contact with sensitive anti-static components or assemblies. The best way to prevent static electricity from building up on the human body is to ground it.

Several personal grounding devices

In industry, wrist straps are the most commonly used grounding device. The wrist strap will safely and effectively remove static charge from your body. To function properly a wrist strap needs to be in proper contact with the skin. A dirty or loose wrist strap can retain stray static charges, rendering anti-static controls ineffective. Conductive footwear or foot grounding may be used to supplement wrist straps.

2. Isolation

The next concept is to isolate components and assemblies during storage or transportation. Isolate from charged objects or charged electrostatic fields. Insulators are the best way to prevent ESD damage during storage or transportation. Since grounding cannot drain away static charges or insulate, it is necessary to isolate sensitive components and assemblies from them. Reducing the use of conventional plastics and other types of insulators in stationary work, shipping, and handling areas is the best way to isolate products from the insulators. Isolation can also be accomplished by restricting access to an entire work area or workstation.

3. Anti-static shoes

Finally, we take advantage of the fact that static charges cannot enter containers made of conductive materials or conductive layers. This effect is called the Faraday cup effect. When storing and transporting electronic components or loading circuit boards, ensure that containers with similar Faraday cup characteristics are used. These containers will be isolated from electrostatic discharge injuries.

4. Neutralization

Use static elimination equipment, the main component of which is an ion generator. Neutralization is important because grounding and isolation will not be able to release charge from insulators such as synthetic cloth or conventional plastics. The neutralization or removal of charge from an insulator that is naturally generated during process operation is called ionization. Ions are simple charged substances that exist in the air. Ions are produced by natural energy substances, including sunlight, lighting, open flames and radiation.
