Why do smt workshops wear anti-static bracelets

In most electronics factories, the most common is the anti-static wristband. I believe many people are wondering why workers need to wear anti-static wristbands when they are working? What's the harm if I don't wear it? Today, the editor of Anhui Yingteli will take you to understand the principles and operations of the anti-static bracelet?

1. The principle of anti-static bracelet

The principle of the anti-static bracelet is to guide the static electricity of the human body to the earth through the wrist strap and the grounding wire. When in use, the wrist strap is in contact with the skin, and ensure that the grounding wire is directly grounded, so that the maximum effect can be exerted. Wear this anti-static wrist strap, which can safely remove static electricity generated in the human body within 0.1 second. The grounding wrist strap is the most basic and most commonly used anti-static equipment.

Through the electrostatic bracelet, the static electricity of the human body can be pushed to the collection area. The conductive plate in the collection area can neutralize the charge of the human body due to charge induction. In addition, the outermost screw is to prevent a large amount of static charge from being introduced instantly when people come into contact with a high static power source. At this time, electrostatic equilibrium can be achieved by discharging the air.

Second, the role of anti-static bracelet

1. In terms of performance: the anti-static bracelet is mainly used to help reduce the voltage of the human body, and introduce the static electricity in the human body to other places through skin contact with the wrist.

2. From the perspective of production: when workers are working, the static electricity generated by the friction between the human body and clothing equipment can easily cause damage to the pcba board, which increases the difficulty of processing and the cost of materials. Wearing anti-static bracelets and anti-static clothing can be effective Avoiding static electricity in the workshop as much as possible has become a rigid requirement of the smt production workshop.

3. Where is the anti-static bracelet suitable?

It is widely used in all positions that require manual operation in the smt processing industry and production line;
