Rainer Thüringer studied physics from 1971 to 1977 and was awarded the Doctor’s degree in 1980 for his thesis on high-frequency ion sources in plasma physics. This shifted his focus to circuit boards. During his ten-year-long occupation in the industries for circuit boards and assemblies as a product manager and manufacturing supervisor, his area of specialization was design and manufacturing of impedance-controlled high-speed assemblies.

Since 1993, Prof. Thüringer lectures at THM, EI department in Giessen – specialized in assembly and device construction as well as electromagnetic compatibility (EMC) and high-speed design. In our EMC test lab for lectures and pre-compliance measurements, research theses are put into practice.

In September 2013, Prof. Thüringer was elected as member of the FED executive board (German professional association for design and manufacturing of circuit boards and assemblies); to date, he is still in charge of the professional training and advanced vocational training. Since 2002, he is also a member of the Steering Committee of IPC Designers Council, the American partner company of FED; here, he works on the conceptualization of internationally standardized modules concerning vocational training for the correct operation of circuit board and high-speed design for EMC.

 Joscha Schmidt started his career as mechatronics technician. Afterwards he absolved a dual study at Studium Plus and gained his Bachelor's degree in general electrical engineering (B. Eng.). In addition he competed his master's thesis in 2019 in the space electronics working group leading to a Master's degree in electrical engineering and information technology (M. Sc.). An existing concept of a radiofrequency generator was modified to supply plasmas with high power pulses.

Since August 2019 Mr. Schmidt is employed at the Institute for Surface Modification (IOM) in Leipzig and since October 2019 he is guest scientist at the THM. The aim of his research is to make the concept of synchronized heating of pulsed metal plasmas for coatings that was developed in his master's thesis available.
