The main reason why static electricity cannot be eliminated
Electronic processing companies and semiconductor factories have taken many anti-static protection measures. Static accidents still exist. The wrong anti-static law is one of the causes of the accident. Based on the problems found in the customer's production site for many years, the following errors are summarized How to use it or the misunderstanding of electrostatic protection, write it down and share it with everyone, I hope it can help all users and make their product quality to a higher level.
1. The anti-static elimination equipment has not been tested as required for a long time, and some do not have the function of eliminating static electricity but are still in use. For example: ion fan, the surface of ion needle is already covered with dust, and ion wind cannot be generated at all. The ion fan has lost the function of eliminating static electricity.
2. Wrong use of anti-static tools, such as incorrect use of the wrist strap, the anti-static wrist strap must be in close contact with the human body.
Wrist straps are relatively easy to damage, so they must be checked every day. Good wrist straps will not conduct electricity because workers wear too loosely. So the best way is to use wrist strap online monitors to monitor in real time. However, many companies don't even have a wrist strap tester. An anti-static wrist strap has been used for many years (the national standard requires that it be replaced every six months), so it will not be able to discharge static electricity.
3. Anti-static shoes and clothes are not worn at the same time. In addition to wearing anti-static shoes, people also need to wear anti-static work clothes to better control the body's static electricity. Because clothing can also carry high static electricity in the process of sports friction, especially now that most clothing is made of chemical fiber, it can generate thousands of tens of thousands of volts of static electricity.
The inspection on the production site has proved that if people only wear anti-static work clothes and do not wear anti-static shoes and do not have a good anti-static floor, the anti-static effect will not reach the standard.
Eliminating static electricity is a long-term systematic project. Therefore, hardware decoration alone is not enough. Professional anti-static regulations must be followed. For example, how to wear an anti-static wrist strap is qualified and anti-static. Electrostatic products must be included in how often they are tested.
