I.Overview
In PCB (printed circuit board) manufacturing, the deionized water (DI water) treatment system is the core equipment in the cleaning process. Its function is to remove ions, particles, and organic matter from the water to prevent residual contaminants from causing circuit short circuits, corrosion, or signal interference.
II.Core Process Combination
Raw Water →Pretreatment →Reverse Osmosis (RO) →Mixed Bed Ion Exchange →Terminal Precision Filtration + UV (Ultraviolet) →DI Water Storage Tank + Circulation System
III.Water quality of DI water in PCB cleaning
