At our site in Stockstadt am Main, we perform all processes in manufacturing from development to series production, which, in turn, makes our customers depend less on long supply chains and lengthy transportation routes. Up-to-date equipment and skilled specialists facilitate first-class development and manufacturing.

Design and manufacturing of electronics

Manufacturing Services

As an expert EMS provider, we offer one-stop contract manufacturing of electronic components and devices. Thus, we can also cater to individual requirements so as to supply the product tailor-made to your expectations. Forging close and equal partnerships, we are our customers‘ long-term technical companion. 

From prototype to high-volume manufacturing – From the get-go, you will benefit from the high standards of quality and reliability we have established in our production. In addition to PCB assembly and soldering units made by renowned manufacturers, we have developed our proper function and load test rigs. And, last but not least, our highly qualified and committed employees ensure reliable large-scale manufacturing of first-class electronic products.






We purchase large quantities of electronical and mechanical components in particular from international suppliers and, in addition to that, have a large warehouse near our plant. Long-term cooperation with our suppliers and producers ensures delivery reliability and high standard of quality of our products.

Product Planning

Our material resource planners work with up-to-date EDP systems for planning, simulating and managing manufacturing. We are always customer focused and a dedicated contact person will be there to respond to your requests and questions any time.

Your technology partner in the Rhein-Main area.


Our in-house manufacturing floor is located right next to our research and development department and is equipped with cutting-edge machines, so that we can manufacture any lot size from extremely small to large and even individualized products cost-effectively. Several assembly lines provide the capacity to carry out multiple orders simultaneously. We can see through the whole value-added process from the first idea to the final product in our house, which creates the best platform to respond to customer requirements flexibly and also makes us your powerful technology partner in the long run.

Final Assembly 

In addition to individual assembly workspaces, we rely on product-specific assembly lines for large-scale manufacturing, where our employees are working side-by-side with state-of-the-art industrial robots.

Testing Laboratory

All components and products are tested according to their intended use – from function and load tests to targeted aging (burn-in).


Quality Management

In our opinion, “Quality is not tested, but made.” That is why we apply high standards of quality from the very beginning of development and, thus, achieve low scrap and failure rates. And that, in turn, enables us to achieve optimal product quality for our customers in multidisciplinary teams using first-class testing and rework stations.


The logistics department supplies our manufacturing with the relevant commodities and eventually takes care of the timely dispatch of the finished product by a forwarding agent or a parcel service – safely stowed in disposable or returnable packaging.

Repairs Department

In the unlikely event that a product should be defective despite our high quality standards, we can remedy defects at our state-of-the-art rework stations and even rework individual components if necessary.


Using holistic development concepts, we take the high standards concerning the safety of electronic products into consideration from the very beginning. Read more >
