High precision manufacturing technology of mobile phone metal label

The invention discloses a high precision manufacturing technology of a mobile phone metal label. The high precision manufacturing technology comprises the steps of degreasing treatment of the surfaceof a metal plate, photosensitive adhesive preparation and screen printing, exposure, developing, etching, electrophoresis painting and drying. Through the acid resistance and light sensitivity of polyvinyl cinnamate and the high resolution of phthalocyanine, configured photosensitive adhesive has super-high corrosion resistance and light sensitivity, it can be ensured that the photosensitive adhesive can not fall off due to corrosion, and the problem that precision is poor due to etching in the later period is avoided; by using a horizontal spray etcher to conduct etching, an etching solutioncan uniformly make contact with the metal plate, so that precision of etching can be further increased; and a method of electrophoresis painting is adopted, thus the paint layer thicknesses of all parts of the metal plate are
