| titleOfInvention | Stripping liquid for photosensitive dry film and production method and application thereof |
| abstract | The invention discloses a photosensitive dry filmThe stripping solution comprises inorganic base, organic base, solvent, additive and water; wherein the alkali equivalent is 0.4-1.25mol/L, the content of inorganic alkali is 0.5-2g/L, and the adding volume of the organic alkali accounts for 2-5% of the stripping liquid. The invention takes organic base as a main component for stripping the film to react with a dry film polymer, and simultaneously, a certain amount of inorganic base component is added to supplement OH in the process of stripping the film ‑ The concentration of (c); the alcohol ether solvent with high boiling point can better play the role of permeating and swelling the dry film. The aromatic azole chelate additive is a film forming substance with specific affinity with metal, so that the oxidation corrosion of the surface of the conductive film layer in the film stripping process is avoided. The dry film stripping device is simple and safe in configuration, strong in dry film stripping capability under the normal spraying and stamping operation condition, and high in production efficiency and yield. |
