Laser Micro Material Processing Influenced by Wavelength and Digitalization

With a diversified lecture program on welding of copper with visible wavelengths, ultrashort-pulse processing with different wavelengths, smart production systems, intelligent inline process monitoring as well as “pecha kucha” presentations on non-destructive testing (NDT), the “23rd seminar on lasers in electronics production and precision engineering” took place in Fürth, Germany, on March 10 and 11, 2020.

Highlights were the talks of the opening speakers Prof. Randolf Hanke (Development Center X-ray Technology EZRT / Fraunhofer Institute for Integrated Circuits IIS, on the future of NDT and X-rays in the context of Industry 4.0), Berndt Zingrebe (retired CEO of Sill Optics, talking about sixty years of affinity with lenses – changes in production), Dr. Jan-Philipp Weberpals (Audi AG, on laser remote welding of aluminum: holistic provision of data for the process chain) and Dr. Fabian Wein (Friedrich-Alexander-Universität Erlangen-Nürnberg, on Process-oriented design optimization – opportunities and limitations).

Unfortunately, not all registered persons were able to participate in the event as planned due to various travel restrictions caused by the increasing spread of the corona virus. In the end, more than one hundred participants made their way to Fürth. As a consequence, digital transformation made up not only a large part of the seminar program, this year. Because of the special situation, one lecturer was connected with the audience remotely and gave his talk from afar for the first time in the history of the seminar – digitalization made it possible.

Regardless of the unfavorable conditions, the attendees took advantage of the opportunity to intensively discuss the potential of laser micro material processing for the technological challenges of the future. Good possibilities for this provided the accompanying exhibition, where 17 exhibitors presented their products and services, as well as the traditional evening event. This time, magician and mentalist Tom Duval astonished the visitors during the evening event with his tricks and gave rise to conversations the next day, as well.

The “24th seminar on lasers in electronics production and precision engineering” will take place in Fürth on March 16 and 17, 2021. More information will be available via the LEF website in autumn of 2020. (Source: BLZ)
