On September 18, 2018, “OFweek 2018 14th China advanced laser technology application summit and annual selection and award ceremony of” vico cup “laser industry was officially held in Shanghai. Wang feng, general manager of wuhan lingyun photoelectric technology co., LTD., introduced the application of laser fine machining in advanced manufacturing of 3C electronics in the keynote speech.
Wang feng first introduced the development process of lingyun photoelectric. According to his introduction, lingyun photoelectric currently main products include precision micro removal, precision micro connection and precision fine marking three categories, in wire cutting, thin film cutting, laser paint removal, laser pointer soft brazing, laser welding, laser curing, engraving mark, color change mark and other aspects have more applications.
In the field of laser precision welding, wang feng introduced steel sheet, plastics, non-ferrous metals, nonferrous metals and refractory materials, and compared the welding laser parameters and welding effects of CW, YAG and QCW. In the specific application solution, wang feng introduced the application scheme of laser in 3C electron from three angles: different thermal effect, different wavelength and different pulse width.
