Precision etching technologyIssuing time:2024-07-17 16:56 When it comes to "etching", people often only think of its harm. Today, under the careful packaging of science and technology, precision etching technology can also make corrosion play its due application value, turn material decay into magic, and showcase a beautiful scenery. Etching surface treatment is the use of the principle of dissolution corrosion to effectively remove the coating or protective layer of the area to be etched when in contact with a chemical solution, forming a concave convex or hollow shaped effect. It is widely used in the processing of lightweight, instrument panels, nameplates, and thin workpieces that are difficult to process using traditional processing methods; After continuous improvement and development of process equipment, it can also be used for precision etching of electronic thin film parts in aviation, machinery, and chemical industries. Especially in semiconductor processes, etching is an indispensable technology. Precision etching surface treatment（Photo Etching） Etching surface treatment, abbreviated as photolithography, uses photographic methods to create a corrosion-resistant film image to protect the surface. It is a method of etching metal, plastic, etc. with the help of chemical corrosion agents to produce surface textures. It can achieve photo etching surface treatment for jewelry, nameplates, and trophies, with a high etching speed of 50-100 microns/5 minutes, suitable for single or large quantities. 1. Most metals are suitable for photo etching treatment, such as stainless steel, aluminum, copper, nickel, nickel, molybdenum, tungsten, titanium and other metal materials. The etching speed of aluminum is fast, while the etching speed of molybdenum and tungsten is slow. 2. Glass and ceramics are also suitable for etching surface treatment, but require different photoresist and chemical substances |
