Circuit, PCB Layout & Firmware from Rostock – Assembly via Our Premium Partner

SMD assembly (Surface Mount Device) is the standard process for modern electronics. Assembly of your boards is handled by our long-standing premium partner in China – precise and reliable, from resistors and capacitors in package sizes down to 0402, through fine-pitch ICs, to complex BGA packages. The specifications come from Rostock: we define the assembly data, layout and process parameters.

The partner's reflow soldering process uses controlled temperature profiles tailored to the requirements of your assembly. The result: consistent solder joints, minimal thermal stress on components and reproducible quality – batch after batch. Mixed assembly with through-hole THT components (selective or wave soldering) is implemented this way too.

For our own GPS tracker boards, we engineered the SMD assembly of NB-IoT and LTE modules, GNSS receivers and LoRaWAN radio chips. This experience with RF components and their sensitive requirements for soldering temperature and placement feeds into your layout, your assembly specifications and the coordination with the partner.

Good electronics starts with circuit design – and this is exactly our core competence in Rostock. We develop new circuits or optimize existing designs. Our focus is on practical, production-ready solutions – not theory. This also includes component selection: matched to function, availability and budget, on request including procurement of PCBs and components by us or our partner.

In PCB layout, we consider manufacturing requirements from the start (Design for Manufacturing, DFM). This means: optimal pad geometries for reliable solder joints, sufficient clearances for machine placement at the partner, well-designed copper areas for thermal management and clean signal routing for EMC compliance. This ensures the assembly data handed to the partner is ready for production.

Our competence shows in our own products: the GPS tracker PCB combines NB-IoT, LTE Cat M1, GPS/GLONASS/Galileo and LoRaWAN on a compact assembly – circuit, layout and firmware developed in Rostock. This requires careful RF planning, impedance control and separation of sensitive analog from digital circuit sections – challenges we master daily.

Fast availability of functional samples is critical for your development cycle. Through our long-standing premium partner in China, we deliver functional samples in the shortest time – typically within one to two weeks, depending on complexity and component availability. Engineering, assembly data and sign-off remain in Rostock.

Our strength lies in end-to-end support: whether first functional samples, revised versions or the pilot run before series production – we steer the process from circuit through layout and firmware to sign-off. This way we adapt to your iteration cycles without you having to coordinate with the manufacturer yourself.

For scaling to series production, we jointly optimize the manufacturing process with the partner: bills of materials are checked for availability, placement programs and test procedures are standardized. This ensures that series quality matches the released sample. There is no fixed minimum quantity – we scale to suit your needs, from a single sample to ongoing series production.
