In the 5G era, small-scale customized production mode will not only gradually replace traditional mass production, but also usher in new industrial changes in design modification, production cycle, logistics, etc. For its product diversification, customization, flexibility and other requirements, the etching process can effectively make the product achieve high precision and micron-level tolerance.

5G mobile devices with technical depth is the use of folding screen, flexible screen, currently mainly used in cell phones, notebooks, car stretch screen, folding screen, scroll screen, etc., repeated folding process will produce great loss, different materials produce different results, but its process Huawei mate Xs using double-layer CPI, which is a composite material, double-layer structure of CPI to prevent water permeability Breathable, to enhance the reliability of the product. Folding screen, flexible screen etching pursuit of extreme micron-level tolerance, the smallest control of the aperture can be ± 0.01MM, the thickness of the extreme up to 0.03MM-1.0MM. mainly through the pre-treatment of metal, the use of plate exposure, after the development, the etched area of the protective film removed, so that the metal contact chemical solution, the use of two positive graphics through the two sides of the chemical grinding to dissolve the corrosion of the role. The effect of forming concave and convex or hollow molding is formed. Compared with the traditional stamping process, the stamped metal screen will make the material burr and roll the edge, the processing cost is high, and the material is also easy to deform, while the etching can make the material burr-free, no roll the edge, the appearance is accurate and the development cost is relatively low.

Zhuolida etching has the etching line of CHEMCUT in the United States, the light painting machine in Israel, AUTOMA automatic roll-to-roll exposure machine in France and other advanced production equipment, which can solve the 5G industry solutions with the precision of tolerance micron level, and its products involve 5G center conductor, conductor board, homogeneous temperature board, microwave antenna, LIDAR, folding screen successful practice.
