Why wear anti-static shoes and anti-static wrist strap
Many people will ask, why wear an anti-static wrist strap when wearing anti-static shoes? This is actually a very good explanation, because both are designed to reduce the accumulation of static electricity and lead the static electricity of the human body to the ground. If the workshop operator has been sitting in front of the workbench, the anti-static wrist strap can provide better protection, but you still have a lot of time to move around in the workshop when you are not in front of the workbench. If there are no anti-static shoes, high voltage will be generated when the staff walks.
When the anti-static wrist strap worn by the worker enters the workshop, the comprehensive tester is still effective, and the wrist strap fails during the production process. At this time, every electronic component touched by the worker may be damaged and broken down, causing serious losses. So this is why you must wear anti-static shoes when wearing an anti-static wrist strap.
The anti-static wrist strap is a device that is worn on the human wrist to release the static charge of the human body. It can be divided into linear and wireless. It is composed of anti-static elastic band, movable snap buckle, spring cord, protective resistor and chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn. Wearing an anti-static wrist strap can safely remove the static electricity generated in the human body within 0.1 seconds. The principle of the antistatic linear wrist strap is:
The static electricity of the human body is conducted to the earth through the wrist strap and the ground wire. When in use, the wrist strap is in contact with the skin, and the grounding wire is directly grounded for maximum effect. The grounding wrist strap is the most basic and commonly used antistatic device.
The principle of the anti-static wireless wristband is: according to the principle of corona discharge and tip discharge, the voltage difference is used to achieve the effect of electrostatic discharge.
