EPSa GmbH

What EPSa GmbH does

EPSa GmbH is a Germany-based electronic manufacturing services (EMS) provider operating under a Design and Manufacturing Services (DMS) model that integrates product development and industrial-scale series production at a single site. Headquartered in Saalfeld with an engineering and development center in Jena, the company employs 190+ people (including 30-50 engineers) and traces its operating heritage to a 1911 Zeiss Jena precision/optical workshop, giving it more than 110 years of continuity in electronics manufacturing. Its revenue streams span hardware sales (PCB assembly, SMT/THT manufacturing, cleanroom production, box building, mechatronic assembly, cable harnessing) and project-based professional services (product development, NPI/prototyping, testing, logistics, after-sales/lifecycle management). Customers request custom quotes based on development phase and volume, with multi-year contract cadence typical of regulated B2B engagements.

The company's technology stack combines two fully automated Siplace SMT lines, 12-zone nitrogen reflow soldering, vacuum vapour phase soldering, ISO Class 5 cleanroom capacity, and a proprietary NedFlex® PCBA test platform that feeds captured data into an internal optimization database. It is supported by the IHS BOM Intelligence component database (500M+ components) and 30,000+ in-house stocked parts for obsolescence management. EPSa also markets its own Digital Passenger Information (DFI) hardware family — TFT displays from 21 to 65 inches, ePaper signage, a solar-powered DFI Micro Solar unit, and the DigiCube digital advertising column — with the 46-inch DFI TFT certified and approved by Deutsche Bahn.

EPSa serves six verticals: industrial electronics, healthcare & life sciences, energy & cleantech, connectivity & smart metering, transportation & e-mobility, and aerospace & defence. Certifications include ISO 9001, ISO 13485 (medical devices), ISO 14001, ISO/IEC 80079-34 (explosion protection), IPC manufacturing standards, and UL/CSA/FM product safety markings, with DIN EN 9100 and ISO 27001 in preparation. The company is privately held and became part of the SERO EMS Group in November 2024 alongside Solid Semecs BV, SERO GmbH, and Syncron EMS, expanding its development capabilities across software, hardware, mechanical engineering, prototyping, and high-mix low-volume production.
