In the semiconductor device production workshop, due to the dust adsorbed on the chip, the yield of IC, especially VLSI, will be greatly reduced. All operators
As we all know, LED is a semiconductor product. In the actual production process, it is mainly the direct contact and indirect contact between human body and re
1. Sources and hazards of ESD
After friction between two different materials, one is positively charged and the other is negatively charged, resulting in a cer
In the process of pharmaceutical production, there is a large amount of static electricity in drugs or drug containers due to friction, which leads to the adsor
Printing is carried out on the object surface, and the electrostatic phenomenon is mainly reflected on the object surface. The relationship between the two is n
In the production, processing and use of ordinary textiles, it is easy to generate static electricity due to friction and induction. For synthetic fiber product
Since most coatings use various combustible solvents as diluents, the static electricity generated during spraying is very easy to ignite and detonate the gas o
Plastics are polymer materials, and the surface resistance and volume resistance are greater than the 12th power of 10. Therefore, it gives good insulation prop
