Pure water plays an increasingly important role in the electronics industry, mainly in the production of circuit boards and electronic components. Deionized water quality has become one of the important factors affecting the quality of circuit boards, electronic components, production yield, and production costs. Water quality requirements It's getting higher and higher. In the production of electronic components, deionized water is mainly used as cleaning water and used to prepare various solutions and slurries. The use of pure water and the requirements for water quality in different electronic component production are also different.

Process flow for preparing circuit board pure water:
1. Adopt ion exchange method, the process is as follows:
Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → Male resin filter bed → Anion resin filter bed → Yin and Yang resin mixed bed → Microporous filter → Water point
2. Two-stage reverse osmosis is adopted, and the process is as follows:
Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first stage reverse osmosis → pH adjustment → intermediate water tank → second stage reverse osmosis (the surface of the reverse osmosis membrane is positively charged) → Purified water tank → pure water pump → microporous filter → water point
3. The EDI method is adopted, and the process is as follows:
Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → Primary reverse osmosis machine → Intermediate water tank → Intermediate water pump → EDI system → Micropore filter → Water point
The traditional preparation process of circuit board pure water equipment is usually made with ion exchange resin, but the use of ion exchange resin usually requires frequent resin regeneration, which is wasteful of material resources and labor. Our company has practiced for many years and combined the latest Membrane separation technology, often combined with reverse osmosis plus ion exchange system (or EDI) to prepare ultrapure water, this process has the advantage of lower operating costs compared to traditional processes (the regeneration cycle of the ion exchanger is greatly extended) reliable.
