Industrial static protection should be very important
Examples of common electrostatic protection methods:
1. Environmental risk control
2. Process control
3. Grounded
4. Increase humidity
5. Antistatic additives
6. Electrostatic neutralizer
7. Use anti-static appliances
8. Strengthen electrostatic safety management.
The most effective measure is to "connect" the human body with the earth, that is, "ground". Therefore, people should wear anti-static shoes. To keep the human body connected to the ground, it requires that the ground is also anti-static before the static electricity of the human body can be introduced into the ground. Therefore, the ground can be used with anti-static mats, anti-static composite rubber sheets, and connected to the ground with an anti-static grounding wire. Sufficient, you can choose anti-static raised floor, especially when planning and designing the computer room factory building, you can consider choosing anti-static raised floor, if the computer room factory has been fixed and the equipment has been installed, and you don’t want to install anti-static equipment to cause these equipment to stop production, etc. When it is affected, you can also choose anti-static mats, anti-static composite rubber sheets, etc. that are inexpensive and simple to construct.
When people wear anti-static shoes and have anti-static floor mats, anti-static composite rubber sheets or anti-static raised floors, they must have a good anti-static effect? When people wear anti-static shoes and have anti-static floor mats, anti-static composite rubber sheets or anti-static raised floors, they may not have a good anti-static effect. Usually people wear socks and cushion insoles. Young people are prone to sweating. These socks and cushion insoles can also conduct static electricity. However, when the middle-aged and elderly people are dry in the dry season, these socks and cushion insoles cannot conduct electricity. Static electricity, and many manufacturers only require workers to wear anti-static clothes and anti-static shoes, ignoring the adverse effects of socks and insoles, making this anti-static shoes and anti-static floor can not play an anti-static effect. Therefore, a "human body comprehensive resistance detector" is placed at the entrance of the computer room or factory building, which can quickly and accurately detect those who wear unqualified anti-static shoes, socks and insoles.
Wear anti-static clothing and wear an anti-static corded wrist strap. Use the ground wire of the wrist strap to discharge static electricity from the human body.
Control the static electricity in the production workshop
Electronic processing companies often suffer from headaches because they cannot grasp the occurrence of static electricity. It is recommended that staff should not be afraid of static electricity. As long as the staff take protective measures in all aspects, static electricity can be controlled. Static discharge or static dissipation. The work surface is static. An indispensable part of workstations, especially those that are assembled manually. When using anti-static wrist straps, it is necessary to clean the work surface and properly connect to a common point for grounding, and always check whether the grounding is Conduction.
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 occurs. Therefore, we must reduce the electrostatic 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 ensure that the grounding is 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, so that the human body and the wrist strap can reach a better path for discharging static electricity. Conductive footwear or foot grounding can be used or supplement the lack of wrist straps. Workstation grounding device
2. Isolation
The next concept is to isolate vital parts and components during storage or transportation. Isolated from charged objects or charged electrostatic fields. During storage or transportation, insulators are the best way to prevent electrostatic discharge damage. 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 static charges on the surface and remove it before opening.
3. Neutralization
Since grounding and isolation will not release charges from insulators such as synthetic cloth or conventional plastics, neutralization is important. The neutralization or removal from the insulator is called ionization. Ions are simply charged substances that exist in the air. Ions are produced by natural energy substances, including sunlight, lighting, open flames and radiation. We can generate trillions of ions through an ionizer. The ionizer uses high voltage to generate a balanced mixture of charged ions, and uses a fan to help the ions drift to objects or areas to neutralize them. Ionization can neutralize the static charge on the insulator within five seconds, so it can reduce their potential damage. Ionization is not a substitute for grounding or isolation. Ionization only reduces the possibility or risk of electrostatic discharge accidents.
4. Prevention
Prevention is another important measure or device for you. This is the most critical factor in electrostatic discharge control. Other people or you must be aware of the dangers of electrostatic discharge when working with electronic vital parts, understand them, and adapt to them will be more important than any electrostatic discharge control material.
