KATEK Leipzig – from the product idea to series production

Our Leipzig-based EMS service provider has only been part of the KATEK Group since 2021, yet has a long history of success. Formerly known as Leesys, the company is now a leading EMS provider specialising in the design and manufacture of electronics assemblies.

Start-up with 100 years of experience

The success story of our Saxony-based EMS service provider began back in the 1920s, when two electronics pioneers founded Dr. Dietz & Ritter GmbH für Radio- und Gerätebau. During the GDR period, the company operated under the name VBE Nachrichtenelektronik, but continued to concentrate on radio and telecommunications technology.

In 1990, the company was acquired by Siemens AG and in the years that followed manufactured millions of telephones in addition to private branch exchanges and power supply systems. In 2010, the company expanded its range of services and opened up new markets with EMS services, plastics production and complete devices. Two years later, the company was renamed Leesys – Leipzig Electronic Systems GmbH. Quantum Capital Partners AG secured the future viability of the company in 2014 before Leesys was finally incorporated into the KATEK Group in 2021.

Today, at its Leipzig location KATEK has an SMD capacity of 1,380,000 elements per hour – a total of 560 active products can be supplied in batch sizes of 1 to 100,000 pieces.
