Baumüller now offering EMS services

Nuremberg, Germany. In Germany, Electronic Manufacturing Service (EMS) is a growth industry for medium-sized customers, especially for small and medium batch sizes. High-quality services, short communication channels and close personal support, in particular, are of great importance.

Baumüller Nürnberg GmbH is now utilizing its many years of expertise in the field of electronics development and production and expanding its offerings to include EMS services.

Baumüller produces equipment using Surface-Mounted Device technology (SMD) and Through-Hole Technology (THT) in accordance with IPC-A-610 and is certified according to DIN EN ISO 9001:2000. Main areas of experience include power and control technology, small and mid-sized mass production, prototype population and spare parts procurement.

SMD production and push-through mounting

Each PCB has its own serial number, either etched with a laser or printed on a label. The SMD process chain starts with the printing of soldering paste on the PCBs. High-precision lasered soldering paste templates and state-of-the-art fully-automatic equipment are used. Paste application is checked by an integrated camera. As a supplement to SMT, push-through mounting is still an important part of PCB production. The components are populated mechanically with automatic THT equipment or manually at our light pointer tables. The assemblies are then soldered in a wave soldering system or a selective soldering unit in a protective gas atmosphere.

Checking and final assembly

Continual quality control by a powerful fully-automatic AOI system (Automatic Optical Inspection) for SMD population is integrated in the process. This automatic optical inspection is essential for the desired zero-defect production. It is used to identify and document incorrect populations and soldering or poorly positioned components. Depending on the customer’s wishes and the agreement, Baumüller provides a final in-circuit test, burn-in test or operational test for the assemblies produced. The operational and endurance tests carried out with test adapters and electronics rule out just about any malfunctions over the lifetime of the systems. Assemblies can be joined to form complete units during production. State-of-the-art screwdriver technologies with user-guided interfaces are the foundation of zero-defect production here.

Lower costs with EMS

Electronic Manufacturing Services cover all the commissioned work of electronic assemblies, devices and systems, from development to PCB population to polished test concepts and worldwide delivery. In addition, EMS is a method of outsourcing, where parts of production can be outsourced to lower costs so that you can concentrate on developing new products, marketing and sales.
