Ultra pure water is water prepared through precision processes such as distillation, deionization, and reverse osmosis, with a resistivity greater than 18 M Ω. cm or close to 18.3 M Ω. cm (25 ℃). It is necessary for us to understand some relevant popular science knowledge about the application of ultrapure water in the electronics industry, so that we can have a deeper understanding together.

Science Popularization 1: Why does the electronics industry need ultrapure water equipment?

In the production of electronic components, the quality of ultrapure water has become one of the important factors affecting the quality, production output, and production cost of circuit boards and electronic components. In the manufacturing of transistors and integrated circuits, ultrapure water is mainly used for cleaning silicon wafers, and in some production processes, it is used for preparing pharmaceutical solutions, water vapor sources for silicon oxidation, cooling water for equipment, and electroplating solutions. The quality of water quality is directly related to the quality and production efficiency of integrated circuit products. Various electronic components have different requirements for water quality, for example, impurities in water may cause circuit short circuits or deterioration of characteristics.

Electronic ultra pure water equipment, such as www.gd jiajie. com, has emerged and is widely used for high-purity water cleaning in integrated circuit production.

Science Popularization 2: Grade of Ultra Pure Water in the Electronics Industry

The Ministry of Electronic Industry of China divides electronic grade water quality technology into four levels, namely 18M Ω. cm, 15M Ω. cm, 12M Ω. cm, and 0.5M Ω. cm, to meet different production needs. Various electronic devices, including transistors, integrated circuit chips, LCD displays, etc., require a large amount of pure water, high-purity water, and ultrapure water for cleaning and manufacturing in the production process.

Science Popularization 3: Preparation Process of Ultra Pure Water in the Electronic Industry

The preparation of ultrapure water mainly adopts technologies such as ion exchange resin, reverse osmosis water treatment equipment, and electrodeionization (EDI) equipment. These processes not only ensure the purity of water quality, but also to some extent reduce the impact on the environment. Different preparation processes have their own advantages and disadvantages, and enterprises can choose suitable processes based on production needs and environmental considerations.

Science Popularization 4: Characteristics of Ultra Pure Water Preparation Process

Among them, the combination of reverse osmosis water treatment equipment, electrodeionization (EDI) equipment, and polishing mixed bed is considered a very environmentally friendly process. This process does not require the use of acid or alkali for regeneration and can continuously produce ultrapure water with minimal environmental impact.

Science Popularization 5: Specific Application Fields of Ultra Pure Water in the Electronic Industry

Ultra pure water is widely used in the manufacturing process of semiconductor materials, printed circuit boards, integrated circuit products, LCD displays, optoelectronic products, and various high-tech precision products in the electronics industry.

Science Popularization 6: Relevant Standards for Ultra Pure Water

In the electronics industry, the preparation of ultrapure water must comply with relevant standards. The ASTM D5127 pure water quality standard for electronic semiconductor industry in the United States is Type E-1.2, and the Chinese national electronic grade ultra pure water standard GBT11446.1-1997 EW - Ⅰ also provides detailed requirements for water quality.
