How to make assembly line anti-static treatment in electronic industry
Electronic processing companies often suffer from headaches because they can’t grasp the occurrence of static electricity. Runfengyuan ion fan recommends that customers not be afraid of static electricity. As long as you take all aspects of protection measures, you can control static electricity. The work surface is static discharge or static dissipation. An indispensable part of an electrostatic safety workstation, especially those that are assembled manually. When using an anti-static wrist strap, it is necessary to clean the work surface and properly connect to a common point for grounding, and it must be done frequently. Check whether the ground is continuity.
1. Grounding
Grounding is very important to reduce the static charge generated on the conductor. The human body is a conductor and the place where static electricity is generated. Therefore, we must reduce the static charge generated on people who touch sensitive anti-static components or components. The static electricity generated by the human body is best to be grounded through the human body, and the grounding must be good and effective.
Several personal grounding devices
In the industry, the wrist strap is the most commonly used grounding device. The wrist strap will safely and effectively drain away the static charge on the human body. To play the role of a wrist strap reasonably, it needs to be in contact with the skin reasonably. A dirty or loose wrist strap may retain the leaked static charge. Workers with dry skin that make the anti-static control fail must wipe the anti-static hand cream to achieve a better path for the release of static electricity between the human body and the wrist strap. Conductive footwear or foot grounding can be used or supplement the lack of wrist straps.
2. Isolation
The next concept is to isolate vital parts and components during storage or transportation. Isolate from charged objects or charged electrostatic fields. During storage or transportation, insulators are the best way to prevent electrostatic discharge damage from occurring. Since grounding cannot drain away static charges or insulators, it is necessary to isolate sensitive vital parts and components from them. Reducing conventional plastic and other types of insulators in static work, shipping, and handling areas is the best way to isolate products from insulators. Isolation can also be accomplished by restricting access to the entire work area or workstation. 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.
Faraday Cup
This type of Faraday cup is usually used to control electrostatic discharge. It is a metal bag, a conductive bag, and a turnover box with a lid. These Faraday cups can carry these electrostatic charges on the surface and remove it before opening.
