About EES Witte
EES Witte GmbH is an EMS provider in Magdeburg specializing in PCB assembly. The company produces single- and double-sided automated SMD assemblies as well as THD assembly of radial and axial components, complemented by stencil screen printing, jet printing of solder paste, and various soldering processes such as reflow, vapor phase, selective, and lead-free wave soldering. In addition, EES Witte offers assembly of electromechanical modules, enclosure assembly, cable assembly, as well as programming, functional testing and electrical testing. Production ranges from prototypes and pre-series under series conditions to volume production, guided by the standards IPC-A-610 DE and IPC-J-STD-001E, with a comprehensive ESD concept and RoHS-compliant component processing. The service portfolio also includes project management, analysis of production data, and material scheduling including procurement of electronic components, PCBs and mechanical parts. The company employs 35 staff and has been run as a GmbH by Robert Witte since 2025.
