About CLEMENS
CLEMENS GmbH is an electronics company based in Waldbüttelbrunn near Würzburg that has been manufacturing in surface-mount technology (SMT) since 1989. The company develops and produces electronic devices and assemblies, in particular thermocyclers and PCR workstations for life science and diagnostics laboratories, and additionally offers contract manufacturing (EMS) as well as development services (EES). The value chain includes electronics and software development, mechanical engineering design, SMT and THT assembly, reflow, wave and selective soldering, coating and potting, electromechanical assembly of complete devices, as well as commissioning and final inspection. Production is carried out for customers from laboratory technology, medical technology, biotechnology, environmental research and testing technology, including Eppendorf and VWR/Avantor. Quantities range from prototypes and small series up to 5,000–10,000 units per year; PCBs up to 500 × 400 mm are processed. The company is certified to EN ISO 9001:2015, EN ISO 13485:2016 and ISO 14001:2015.
