About Bruns Elektronik
Bruns Elektronik GmbH is an EMS provider (Electronic Manufacturing Services) based in Bad Pyrmont and manufactures electronic modules as a contract manufacturer for customers from SMEs and industry. The service portfolio includes automatic SMT assembly on two lines with five placement machines (Yamaha I-Pulse M20, S20, S10; components from 0402 to 0.4 mm fine pitch), manual THT assembly of wired components as well as reflow, wave and selective soldering under nitrogen atmosphere. In addition, the company offers panel separation by milling, AOI, ICT and FCT testing, visual inspection to IPC-A-610, and device and terminal assembly including packaging. As a full-service provider, the company also takes on development, layout, concept design, material procurement and logistics through to delivery throughout Germany. Production ranges from prototypes to small and medium batch sizes. Production is certified to DIN-ISO 9001:2015 (DQS); since 2020 a newly built production hall has been available at the headquarters.
