How to do a good job of static control in the production workshop of electronic factory
Electronic processing companies often have headaches because they cannot grasp the occurrence of static power. Runfengyuan ion fans recommend that customers do not be afraid of static electricity, as long as you take all protective measures to control static electricity, static discharge or static dissipation work surface is An indispensable part of an electrostatic safety workstation, especially those production workshops that are assembled manually, when using anti-static wrist straps, it is necessary to clean the work surface and properly connect it to a common point. Check whether the ground is continuity.
1. Ground
Grounding is very important to reduce the static charge generated on the conductor. The human body is the conductor and the ground where the static power source occurs. Therefore, we must reduce the static charge generated on people who touch sensitive antistatic components or components. The static electricity generated by the human body is best grounded through the human body, and to ensure that the grounding is good and effective.
Several personal grounding devices
In industry, the wrist strap is the most commonly used grounding device. The wrist strap will safely and effectively discharge the static charge on the person's body, and to play the role of a wrist strap reasonably requires reasonable contact with the skin. A dirty or loose wrist strap may retain the leakage of static charge, so that the anti-static control fails. Workers with dry skin must wipe anti-static hand cream to achieve a better path between the body and the wrist strap to discharge static electricity. Conductive footwear or foot grounding can be used or supplement the wrist strap inadequately.
2. Isolation
The next concept is to isolate components 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. Since grounding cannot discharge static charges or insulators, it is necessary to isolate sensitive components and components from them. Reducing conventional plastics and other types of insulators in stationary 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 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.
