The process flow

Among them, the key indicators of ultrapure water such as: conductivity (resistivity), total silicon, pH value, particle size, microorganisms, etc. all have different requirements. Therefore, circuit boards and circuit boards use pure water and ultrapure water. Due to the different process flows, the manufacturing process of ultrapure water is also different.

Note:If you need to know the process flow of a specific industry, please contact customer service.
