The production of printed circuit boards is mainly based on chemical processes, which consume a large amount of water and produce wastewater. From copper-clad foil base to finished printed circuit board, it undergoes multiple chemical water washes, pre-treatment and water washing through chemical electroplating, electrolytic electroplating, and surface cleaning. Clean production should save water resources and water. The chemical solution and cleaning water used are both turned into wastewater.

When performing these operations, circuit board factories should first consider clean production. Clean production in circuit board factories ensures product quality, and the quality of the board and the reputation of the production enterprise are equally important.

There are also printing options available: solder mask ink, marking ink, conductive ink, and plug hole ink are retained on the printed circuit board of the circuit board factory. They include photo imaging, photo dry film, corrosion resistant thousand film, solvent type, and water-soluble type (with various photosensitive film thicknesses).
