Electronic processing companies and semiconductor factories have done a lot of anti-static protection measures, and static electricity accidents still exist. The use of the wrong anti-static products is one of the causes of accidents. It is not possible to achieve anti-static effects by wearing anti-static overalls. . Based on the problems discovered in the customer's production site over the years, the mistaken use methods or errors in electrostatic protection are summarized.

　　1. Anti-static elimination equipment has not been tested as required for a long time, and some have not been able to eliminate static electricity but it is still in use. For example, an ion blower, the ion needle surface has been covered with dust, and no ionized wind is generated. Such ion The fan has lost its ability to eliminate static electricity.

　　2. Incorrect use of anti-static tools, such as: incorrect use of the wrist strap, anti-static wrist strap must be in close contact with the human body. Wrist straps are relatively easy to damage, so to detect every day, a good wrist strap will be too loose and not conductive because of the workers, so the best way is to use a wrist strap online monitor real-time monitoring. However, many companies 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-yearly replacement), and this does not achieve electrostatic discharge.

　　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 in order to better control the human body electrostatic. Because clothing can also be highly static during sports friction. In particular, most garments today are chemical fibers, which can generate thousands of volts of static electricity.

The production site test proved that the operators only wore anti-static overalls, but did not wear anti-static shoes and did not have a good anti-static ground, and the anti-static effect could not reach the standard. It can be seen that the anti-static measures are multi-faceted to achieve the effect.
