SE-TEC is particularly well-suited for companies that want to have custom electronics manufactured reliably and value personalized support, technical consulting, transparent processes, and long-term partnerships.

Typical customers come from the medical technology, industrial electronics, mechanical engineering, energy and power electronics, railway technology, aerospace, and other technically demanding industries.

SE-TEC combines state-of-the-art manufacturing technology with experienced specialists, high process reliability, and certified quality standards. This results in high-quality electronic assemblies that are manufactured in a reproducible, cost-effective, and reliable manner.

Particularly valuable to customers is the combination of SMT and THT manufacturing, comprehensive testing and inspection capabilities, traceability, materials management, and flexible support from prototyping through to mass production.

SE-TEC not only manufactures assembled printed circuit boards, but also handles the assembly of complete devices. This includes mechanical integration, wiring, programming, functional testing, final inspection, packaging, and shipping.

This way, customers receive a complete, tested, and ready-to-ship product from a single source.

SE-TEC manufactures prototypes, small-batch, medium-batch, and large-volume production runs. The manufacturing processes are designed to handle different batch sizes cost-effectively and with consistent quality.

Thanks to modern SMT lines, established THT processes, and flexible production planning, both recurring production runs and project-based manufacturing orders can be carried out cost-effectively.

Yes. SE-TEC supports customers in the transition from prototyping and sample production to stable mass production. In doing so, the company takes into account production data, material availability, testability, process reliability, and potential areas for optimization.

The goal is to develop an electronic assembly that is cost-effective to produce, reliable, and available over the long term.

In its SMT manufacturing process, SE-TEC handles, among other things, small passive components, fine-pitch components, QFN and BGA packages, and other complex package types. The company is also capable of manufacturing complex layouts and densely populated printed circuit boards.

Feasibility is assessed on a project-by-project basis based on manufacturing data, component specifications, and quality requirements.

In SMT manufacturing, SE-TEC relies on reflow soldering with monitored process parameters and soldering profiles tailored to the product. For thermally demanding assemblies and complex PCB designs,
vapor-phase soldering can also be used.

This makes it possible to create reliable solder joints even in complex assemblies, with high thermal mass, or with sensitive components.

Vapor-phase brazing enables particularly uniform heat transfer and, due to the nature of the process, limits the maximum brazing temperature. This is advantageous for thermally demanding assemblies, high copper content, or sensitive components.

SE-TEC uses vapor-phase soldering, particularly in applications that require exceptionally stable soldering processes and a high degree of process reliability.

Screen printing for solder paste requires maximum precision and repeatability. SE-TEC uses fully automated stencil printers with product-specific print profiles, automatic alignment, and stencil cleaning.

The subsequent automatic solder paste inspection checks the printing process before the circuit boards are sent on to the assembly line. This ensures that only flawlessly printed circuit boards are processed further.

Consistent and verified solder paste application is the foundation for reliable solder joints and reproducible manufacturing quality.

SE-TEC offers wave soldering, selective soldering, and manual soldering as THT soldering processes. The choice of the appropriate process depends on the assembly, components, thermal requirements, and production volume.

By combining various processes, even complex mixed assemblies can be manufactured reliably.

Selective soldering is particularly suitable for assemblies in which only certain THT solder joints need to be processed or sensitive areas must be protected from heat. The process is especially advantageous for densely populated printed circuit boards and complex mixed-component assemblies.

SE-TEC uses selective soldering to achieve precise, repeatable soldering processes that are gentle on components.

Thermally demanding assemblies, such as those used in energy and power electronics, place special demands on PCB design, soldering profiles, thermal management, and process control.

SE-TEC reliably manufactures such assemblies using appropriate soldering processes, such as vapor-phase soldering in SMT production, as well as wave soldering and selective soldering in THT production. Depending on the assembly, the range of components, and the thermal requirements, the appropriate soldering process is selected to ensure reliable solder joints and consistent production quality.

SE-TEC addresses supply bottlenecks through early demand planning, active communication, alternative sourcing channels, and the evaluation of possible

Alternative components. Critical components are evaluated on a project-by-project basis and coordinated with the customer. The goal is to identify risks in the supply chain early on and maintain a stable supply capacity.

Yes, customers may provide their own materials. SE-TEC inspects the materials provided to ensure, among other things, that they are complete, properly packaged, handled in accordance with ESD guidelines, properly labeled, and suitable for use in the manufacturing process.

It is advisable to coordinate these matters early on to ensure that materials, manufacturing data, and production planning are properly aligned.

Obsolescence management involves identifying component discontinuations, limited availability, or technological changes at an early stage and taking appropriate action.

SE-TEC assists customers in evaluating critical components, provides information on product discontinuations, and helps them find suitable alternatives.

At SE-TEC, electronic components are stored in an ESD-compliant manner and in accordance with their specific requirements. Moisture-sensitive components are handled in accordance with MSL guidelines. This ensures reliable soldering processes.

Proper storage is a key factor in ensuring process reliability and manufacturing quality.

AOI stands for Automatic Optical Inspection. In this process, assembled printed circuit boards are automatically inspected visually for components, polarity, solder joint quality, and assembly defects, for example.

SE-TEC uses AOI inspections as a key component of quality assurance in electronics manufacturing.

Yes. X-ray inspection can be particularly useful for hidden solder joints, BGA components, or complex assemblies. It effectively supports the evaluation of solder joints that cannot be inspected visually, or can only be inspected to a limited extent.

X-ray inspection thus complements the other inspection and testing methods.

SE-TEC offers in-circuit testing, functional testing, customer-specific test procedures, and other electrical test concepts. Test programs and test adapters can be developed on a project-by-project basis.

The appropriate test strategy is determined in collaboration with customers based on the assembly, the available test points, the required level of test coverage, and production requirements.

Yes. SE-TEC has its own in-house test equipment and adapter manufacturing facilities. This allows us to efficiently produce test adapters for customer-specific functional tests and to modify them on short notice if necessary.
