Products can be partially etched or not penetrated. It can also be etched on partly machined metal workpieces. Compared with the traditional mechanical processing and laser processing, the etching process has: 1. Can process most of the metals and alloys; 2. High processing accuracy; 3. Can process components with complex shapes; 4. Low processing cost; 5. Process Flexible large or small parts are available; 6. No stress is generated during processing; 7. The product has no burrs; 8. No effect on the main properties of the processed material; 9. New product development is inexpensive and easy to modify; 10. Processing Short cycle and other advantages can produce samples in as short as 7 days. The etching process is suitable for precision processing of small batches, large batches, multiple varieties, small areas, large area metal sheets, ultra-thin plates and surface processing of metal crafts, and can be used to make metal products with semi-etched patterns. We can etch various metal materials with a thickness ranging from 0.03mm-2.0mm; the corrosion processing tolerance can be controlled at a minimum of ± 0.01mm, and the maximum processing area is 1500mm * 1000mm; processing methods: processing by incoming materials; To map processing; The mask can be used in electron beam evaporation, thermal evaporation, magnetron sputtering and other equipment to prepare patterned films and electrodes for various devices such as OPV, OLED, perovskite solar cells, photodetectors, and field effect transistorsand other devices.. So far, we have many long-term customers from universities, scientific research institutes and companies. They include: Shanghai jiaotong university, Tongji university, Shanghai normal university, Northeastern University at qinhuangdao, Southeast university, Research institute of junction microstructure and ultrafast processes, China university of mining and technology, University of science and technology of China, Shanghai institute of technical physics, Chinese academy of sciences, etccompany information NINGBO DonGSHENG INTEGRATED CIRCUIT ELEMENT CO.,LTD was founded in 1976, engaged in the etching industry for 32 years, mainly producing integrated circuit lead frame, hardware etching and other kinds of precision metal etching products, the products cover electronics, machinery, chemical, medical, military, aviation, aerospace, household appliances, sanitary ware, automobile and other industries and fields.Why choose ningbo dongsheng etching?1.Standard 17300m2 self-built factory with waste water treatment system2.Passed ISO9001, ISO14001 certification3.Has 8 experienced engineers and professional quality inspection team4.10 PCS OF etching machines5.Four etching lines6.Comprehensive inspection and quality inspection before shipmentOur goal is to provide one-stop manufacturing solutions to our valuable customers, saving their time and money.
