What are the principles and functions of the anti-static clothing worn by the electronics factory?
We know that especially when the air is dry, the static electricity generated by the human body has a large current. If it touches the chip, it will break the chip and damage the chip. This is especially harmful to our products. At present, the microelectronics factory pays special attention to static electricity. control.
Anti-static clothing is to create a protective touch between people and chips (playing games to play more haha) like the effect of electrostatic clothing is to block static electricity and static shoes are conductive static.
The cloth that makes the electrostatic clothing will not generate static electricity after repeated rubbing. After you put it on, it is to prevent the static electricity generated by your own clothing from inadvertently contacting the electronic components to prevent the static electricity from penetrating the electronic components.
For example: electronic components such as IC.
The antistatic shoe itself is a sole made of conductive rubber. The surface is pure cotton material. Its principle of action is to pass your own static electricity through conductive rubber.
Conducted to the earth to achieve the effect of preventing static electricity. The static shoe cover you said, if you don't touch your skin, will not introduce static electricity generated by yourself into the earth.
The principle of anti-static clothing is also to introduce static electricity generated by the human body into the earth. In addition, we have said before the semiconductor industry how to prevent static electricity? This issue has been explained in the previous period. Because the electronic equipment in the electronics workshop, semiconductor workshop, program control room and other requirements for humidity is generally 40% ~ 60% RH, because the air humidity is lower than 40% RH is very easy to generate static electricity.
Supplementary explanation: The static electricity generated by the human body can reach up to 400,000 volts. The general electronic components can be penetrated with only a few thousand volts of static electricity.
