Why is the ion fan indispensable? The electrostatic adsorption of the ion fan
In the LCD industry, as the glass substrate becomes larger, the ability to attract electric charges is also strengthened. Due to the large size of the substrate, any purification may result in a low yield rate. Like other purification and control industries, the LCD industry is constantly searching for new materials that can handle ESD issues. The anti-static socks used in the clean room are also more likely to use anti-static ion fans, and new materials can also be experimentally invented to replace traditional materials on cotton swabs and rags.
Electrostatic adsorption of ion fan
The most catastrophic problem of ESD control in the clean room is the movement of the staff in the clean room. Because people wear a small amount of polyester fabrics, a small amount of electric charge will be generated. The only way to remove this charge in a clean room is to ground.
In the past five years, people have invented a work clothes system made of carbon fiber and fabric that can provide practical ISO5 (Class100) clean room requirements.

All parts of this type of work clothes have the same conductivity, and there is a conductive connection to the bottom of the foot. Staff working in the clean room can walk through the conductive soles of the shoes when they wear this kind of clothes, instead of grounding through the grounding wire, so they are not limited by the length of the grounding wire.
There is no self-made quick repair method for ESD ion fan control. The key is to control ESD, such as hanging a laminar vagrant fan or placing an ion fan next to the material that needs to control ESD. With the elimination of chip (IC) size, it becomes more and more sensitive to ESD. Nowadays, the control of ESD is not only limited to the protection of the working network, but also needs to control the chip and the staff who consume the chip. Many companies with high-standard requirements are controlling ESD in this way.
The appearance of this kind of work clothes is the effect of high requirements on the product, which helps to reduce the low yield and high defective rate caused by ESD problems in the clean room.
