How to prevent static electricity in air purification workshop? With the centralized air conditioning purification system software, the clean treatment method of natural environment with the same cleanliness level in all rooms is called air purification workshop. It is a method that has begun to develop in clean technology, and it is still used today. This kind of method is suitable for the site with high technology, large total number and the same cleanliness level in the room. However, this kind of method has large investment, complicated operation and management methods, and long development cycle.
Next, let's take a look at how to prevent static electricity in the purification workshop
1. We all know that in North China or in dry winter, the common faults caused by static electricity are far more than those in southwest coastal cities or other seasons. Therefore, in some key sites, such as computer rooms, semiconductor material purification workshops, and instrument production workshops, we should consider the problem of maintaining a certain amount of environmental humidity, Especially for these enclosed central air-conditioned rooms, it is necessary to have certain machinery and equipment to control the ambient humidity.
2. Semiconductor components should be packed in antistatic plastic container or antistatic packaging bag. This kind of antistatic container has excellent conductivity and can reasonably avoid the generation of static electricity. Naturally, those with standards should be packed in metal containers or packed in metal foil.
3. The application of ion air gun, positive ion head, ion air bar and other equipment can avoid static electricity in a certain range.
4. Lay static floor or carpet. At present, the existing plastic floor or carpet products with certain conductivity can reasonably prevent static electricity caused by people's walking.
5. In view of the fact that the operators should wear anti-static hand strap on their wrists, this kind of hand strap should have excellent characteristics of grounding device, and this kind of countermeasure is more reasonable.
