Can the dust-free workshop wear anti-static overalls once and for all?
Electronic processing companies and semiconductor factories have done a lot of anti-static protection measures. Electrostatic accidents still exist. The wrong method of using anti-static products is one of the causes of accidents. It is not the anti-static work clothes that can eliminate the anti-static effect. Based on years of understanding the problems found at the customer's production site, summed up the wrong use or static protection misunderstanding.
1. Anti-static elimination equipment has not been tested for a long time. Some of them have not been used to eliminate static electricity, but they are still in use. For example, ion fans, the surface of the ion needle is already full of dust, and it cannot generate ion wind at all. The fan has lost its ability to eliminate static electricity.
2. Incorrect use of anti-static tools, for example: improper use of wrist straps, anti-static wrist straps must be in close contact with the human body. Because the wrist strap is relatively easy to damage, it needs to be tested every day. A good wrist strap will also be too loose and not conductive because the worker wears it. Therefore, the best method is to monitor the real-time monitor with the wrist strap online monitor. However, there are many companies that do not even have a wrist strap tester. An anti-static wrist strap has been used for many years (the national standard requires a half-year replacement), so that it does not have the effect of static electricity.
3, anti-static shoes, anti-static clothing is not worn at the same time, in addition to wearing anti-static shoes, but also supporting the use of anti-static clothing to better control the human body static. Because clothing can also carry high static electricity during the movement and friction, especially most of the clothing is chemical fiber, which can generate thousands of volts of static electricity.
The production site inspection proves that the operator only wears anti-static overalls, but does not wear anti-static shoes and does not have a good anti-static ground. The anti-static effect can not reach the standard. It can be seen that the anti-static measures are multi-directional to achieve the effect.
