General Manager Pentamaster Automation Germany GmbH


Michael Koelbl, who has been working in the semiconductor industry for over 26 years, started his career with a medium-sized German-based machine manufacturer for wafer laser marking and sorting systems. After graduating in Micro- and Precision Engineering from the University of Applied Sciences in Munich in 1995, Mr. Koelbl worked as a service engineer, installing and maintaining equipment in front-end semiconductor fabs around the world. From 2007 to 2011 he was based in Singapore, where he set up a subsidiary to provide sales and service activities in the growing South East Asian region. Since returning to Germany, Mr. Koelbl has been actively involved in the development of robotic and laser applications as Technical Director and Business Development Manager.

In early 2023, Mr. Koelbl joined Pentamaster, a global supplier of automated test equipment and factory automation systems with customers in the semiconductor, automotive and medical industries. Pentamaster has been offering power module automated test equipment solutions for home appliances application since Y2010. They advanced to the EV industry in Y2018 with a wider range of equipment solutions covering electrical burn-in, assembly and final testing of power modules. With Pentamaster’s presence in Germany, Mr. Koelbl sees a great opportunity to support customers in the booming EV segment. Last but not least, the recently agreed European Chips Act, to strengthen the semiconductor ecosystem in the European Union, will support Pentamaster’s group expansion plan to increase its geographical footprint in Europe.
