Water quality standards for the electronic semiconductor industry:
Our company's electronic grade ultra pure water equipment fully meets the ASTM pure water quality standards in the United States, the electronic grade water quality technical standards of the Ministry of Electronics Industry of China (18M Ω· cm, 15M Ω· cm, 10M Ω· cm, 2M Ω· cm, 0.5M Ω· cm five level standards), the high-purity water quality trial standards of the Ministry of Electronics Industry of China, the pure water indicators for the semiconductor industry in the United States, the water quality standards for integrated circuits in Japan, and the water quality standards for large-scale integrated circuits at home and abroad.

The electronic industry's requirements for water quality:
The microelectronics industry, large-scale and ultra large scale integrated circuits require a large amount of high-purity water and ultrapure water to clean semi-finished and finished products. The higher the integration level of integrated circuits, the higher the requirements for water quality, which also puts forward stricter requirements for the simplicity, automation level, production continuity, sustainability, and other aspects of ultrapure water treatment processes and products.

Application scenarios:
☆ Semiconductor materials, devices, printed circuit boards, and integrated circuits;
☆ Ultra pure materials and ultra pure chemical reagents;
☆ Laboratory and pilot workshop;
☆ Surface polishing treatment for automobiles and household appliances;
☆ Optoelectronic products;
☆ Other high-tech micro products;

Typical electronic grade ultrapure water preparation process:
☆ Pre treatment - reverse osmosis - water tank - cation bed - anion bed - mixed bed - pure water tank - pure water pump - ultraviolet sterilizer - refined mixed bed - microporous membrane filter - water target
