Received calls from many friends, consulted the establishment of the new factory, how to build an anti-static system in the production line? Because all industries are sensitive to static electricity, the anti-static system to be built is of course different. However, the principle of protection against static electricity is similar. Let me share with you my personal experience how to take anti-static measures in static sensitive areas.
First of all, people will generate static electricity during activities such as walking, standing up, etc. The human body is the most common static power source, so the static protection of the human body is the most important. The most effective measure to control the static electricity of the human body is to make the body "connect" to the earth or "ground". Therefore, the staff on the production line need to wear anti-static shoes, and the ground needs to be laid with anti-static floor or anti-static mat, and the static electricity is discharged to the ground with anti-static ground wire.
Secondly, wearing anti-static shoes will definitely play a good anti-static effect when laying on anti-static floor or anti-static floor mat? Usually people wear socks and pad insoles. Some people tend to sweat. These socks and pad insoles can also conduct static electricity. However, some people can't guide the dryness of the shoes during the dry season. Static electricity, and many manufacturers only require workers to wear anti-static clothing and anti-static shoes, ignoring the adverse effects of socks and insoles, so that this anti-static shoes and anti-static ground can not play an anti-static effect. Therefore, a "composite body resistance detector" is placed at the entrance of the machine room or factory building, which can quickly and accurately detect those who wear unqualified anti-static shoes, socks and insoles.
Third, the staff must wear anti-static clothing in addition to anti-static shoes to better eliminate static electricity. Because the static electricity generated by people rubbing with clothing during activities is usually around several thousand volts, enough to break through the precision components in the circuit board. Therefore, wearing an anti-static suit is a must. The protection of hair static electricity is also very important, so wear an anti-static suit and also need to wear an anti-static cap correctly.
In addition to the elimination of human body static electricity on the production line, the workbench and tools should adopt electrostatic protection measures. We recommend to produce on the workbench with anti-static mat or stainless steel workbench, and equipped with anti-static chair. Because in addition to the static electricity generated by the anti-static workbench itself, once people have generated static electricity during the operation, static electricity can be introduced into the anti-static floor through the anti-static workbench in time, and then released into the earth. There are many anti-static tools. For example, anti-static tools commonly used in electronics factories include anti-static wrist straps, anti-static smash sticks, anti-static scorpions, anti-static brushes, anti-static sprays, anti-static smoking machines, anti-static Electric soldering station and so on.
Finally, it is also not to be overlooked that anti-static equipment, clothing, tools are regularly tested, so it is necessary to have some anti-static test equipment in the construction of anti-static system, such as human body comprehensive tester, wrist strap tester, surface resistance test Instrument, electrostatic field tester, etc.
