Static Electricity Control In The Production Workshop Of Electronics Factory
Electronic processing companies often have headaches because they cannot grasp the static power supply. We advise customers not to be afraid of static electricity. As long as you do all kinds of protective measures, you can completely control static electricity. Electrostatic discharge or static dissipative work surface is a static electricity safety. An integral part of the workstation, especially those that are assembled manually, when using an antistatic wrist strap, it is necessary to clean the work surface and properly connect to a common point, and always check if the grounding is Turn on.
1, ground
Grounding is very important to reduce the static charge generated on the conductor. The human body is a conductor and is the place where the static power source occurs. Therefore, we must reduce the static charge generated by people who are exposed to sensitive anti-static components or components. The static electricity generated by the human body is preferably grounded through the human body, and it is necessary to ensure that the grounding is good and effective.
Several personal grounding devicesIn the industry, the wrist strap is the most commonly used grounding device. The wrist band will safely and effectively remove the static charge from the human body, and the proper use of a wrist band requires proper contact with the skin. A dirty or loose wrist strap may retain the static charge that is leaking, making the anti-static control fail. Workers with dry skin must wipe the anti-static hand cream to achieve a better path to discharge static electricity between the human body and the wrist strap. Conductive footwear or foot grounding can be used or supplemented with insufficient wrist straps. Workstation grounding device.
2, isolation
The next concept is to isolate the components and components during storage or transportation. Isolation from charged objects or charged electrostatic fields. Insulation is the best way to prevent electrostatic discharge damage from occurring during storage or transportation. Since grounding cannot remove static charge or insulators, it is necessary to isolate sensitive components and components from them. Reducing conventional plastics and other types of insulators in stationary, shipping, and handling areas is the best way to isolate products from insulators. Isolation can also be done by limiting access to the entire work area or workstation. Finally, we take advantage of the fact that static charges cannot enter a container made of a conductor material or a conductor layer. 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 and that these containers will be isolated from electrostatic discharge injuries.
Faraday Cup
This type of Faraday cup is commonly used to control electrostatic discharge, which is a metal bag, a conductive bag, and a covered turnover box that can carry these static charges on the surface and remove it before opening.
