Our goal? To realize customized electronic solutions that perfectly meet your requirements – quickly, efficiently and with the best quality.

PCB Assembly
Sample Quantities to Series Production:
We specialize in the production of electronic components in the low-mix/medium-volume to high-mix/medium-volume range. Our fully automated assembly lines guarantee the highest production precision and efficiency.
Our services include:
- Prototyping: Quick and cost-effective production of initial samples.。
- Series Production: Optimized and lean processes for maximum efficiency.
- After-sales Service: Long-term support, repairs and further development.
Prototype production
Combining speed and precision:
The development of a new product often begins with the creation of a prototype. Our EMS rapid prototyping services enable you to receive functional sample components in a very short time.
Advantages of our prototype production:
- Rapid component sourcing through strong supplier partnerships.
Flexible production control for time-critical projects. - 48-hour prototype expedited service.
- Engineering support for AZ sample components
We have an experienced engineering team that can realize your ideas in the shortest time so that you can optimize and validate your products faster.
Highest quality mass production
Reliable and on time:
As an EMS service provider, we specialize in the mass production of various electronic products. Our EMS series production is well suited for assembly in the low-mix/medium-volume to high-mix/medium-volume range. We ensure that each product meets the highest quality standards. Through efficient processes and optimized production procedures, we guarantee you reliable and on-time delivery.
Optimized processes in our series production:
- Lean processes and balanced overhead
- SMT assembly
- Reflow and vapor phase soldering
- Hand assembly and soldering work
Box building (full assembly) - 2D traceability
Validation, test procedures, electrical testing and quality control - Documentation
After-sales service and product development
For the life and competitiveness of your electronic products:
Our responsibility does not end with the delivery of your product. We offer comprehensive services and long-term support to ensure the longevity and competitiveness of your electronic products:
- Obsolution management: Early information about components that are no longer available.
- Redesign and upgrading: Adaptation and further development of your product.
- Maintenance and repair: Long-term functionality and reliability.
With our after-sales service, we provide you with continuous technical support so that your products always remain up-to-date and meet the highest quality standards over a long life cycle.
Highest level of quality assurance
Quality is our top priority. We use the latest test methods to ensure that your products function reliably:
Automated Optical Inspection (AOI): Automated defect detection on printed circuit boards.
Functional testing: Ensuring operational capabilities under real conditions.
Traceability: Traceability of all components and processes.
With extensive documentation, we offer you maximum transparency – a decisive advantage for your quality and process assurance.
