Description

Technical Field

[0001] The invention relates to the technical field of ink wastewater treatment, in particular to a wastewater treatment device for preparing ink for photosensitive circuit boards. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. Ink includes main ingredients and auxiliary ingredients. They are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of resin, pigment, filler, additive and solvent, etc. It is used for various printings such as books, packaging and decoration, architectural decoration and electronic circuit boards. PCB circuit board generally refers to printed circuit board, also known as printed circuit board, which is an important electronic component, the support of electronic components, and the carrier of electrical connection of electronic components. Ink plays a role in protecting copper foil in production, so that the copper foil is not exposed to the outside, otherwise it will affect the subsequent processes. In the production process of circuit boards, circuit board wastewater will be generated during the processes of grinding, etching, electroplating, hole metallization, development, and stripping.
