Application of industrial ultra pure water equipment in semiconductor industry
The role of ultra pure water in the electronic semiconductor industry:
Ultra pure water equipment in electronic semiconductor industry usually consists of multi-media filter, activated carbon filter, sodium ion softener, precision filter, etc. The raw water tank, intermediate water tank, RO pure water tank and ultra pure water tank are equipped with liquid level control system, high and low pressure water pumps are equipped with high and low pressure protection devices, online water quality detection and control instruments, and PLC programmable controller is used for electricity, so that no one is on duty. At the same time, the method of unifying the recommendation and customer requirements is adopted in the process material selection, Compared with other similar products, the equipment has higher cost performance and equipment reliability.
Electronic grade water quality technology is divided into five industry levels
1. The national standard of high purity water is: GB 1146.1-89 to GB 1146.11-89.
2. The electronic grade moisture content of high purity water can be divided into five grades: Grade I, grade II, grade III, grade IV and grade v. the standard is formulated according to ASTM electronic grade standard.
3. The resistance is 18m Ω. cm、15M Ω. cm、10M Ω. cm、2M Ω. cm、0.5M Ω. Cm to distinguish different water quality.
Advantages of ultra pure water equipment for electronic semiconductor industry
Industrial ultra pure water equipment can continuously and stably prepare high-quality ultra pure water, and will not stop operation due to resin regeneration. The equipment structure design is relatively close, so it occupies a small area and can save a lot of space for enterprises. Industrial ultra pure water equipment needs to be debugged before leaving the factory, so the probability of equipment failure is small, and the daily maintenance and maintenance are very important Maintenance and other operations are very simple.
The application of industrial ultra pure water equipment in the electronic semiconductor industry is very important. It provides sterile and impurity free high-purity water for the production of the industry, and ensures that the quality of electronic products will not be affected by the water quality.
