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 method 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 static protection, write it down and share it with you, 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, such as ion blowers, the surface of ion needles has been 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, for example: incorrect use of the wrist strap, the anti-static wrist strap must be in close contact with the human body.
The wrist strap is easy to be damaged, so it needs to be checked every day. A good wrist strap will not conduct electricity because the worker wears it too loosely, so the best way is to monitor it in real time with the wrist strap online monitor. 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 the effect of discharging static electricity cannot be achieved.
3. Anti-static shoes and clothes are not worn at the same time. People must wear anti-static work clothes in addition to anti-static shoes 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.
On-site inspections at the production site have shown that people who only wear anti-static overalls, if they 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 should be included in how often they are tested.
