Quality assembly

Reliable connection technology for high loads and currents

In THT manufacturing, through-hole components are often soldered and tested manually after through-hole assembly. Despite being more labor-intensive, THT remains indispensable when mechanical resilience or high current carrying capacity are required.

Experience, precision, process reliability.

Our conventional assembly combines qualified specialists with modern equipment. Many years of experience and the utmost care ensure consistent quality in wave, selective, and manual soldering.

Selective soldering

Learn more

Targeted soldering processes for complex cases

Selective soldering is a programmable, precisely controllable process for individual THT components on highly integrated printed circuit boards or double-sided SMT boards.

Advantages: high soldering quality; reliable process reliability; reproducible results; precise control of flux quantity and soldering time.

Wave soldering

Learn more

RoHS-compliant, precise, and gentle on materials.

We use microprocessor-controlled double wave soldering systems with integrated spray fluxers to reliably solder SMT, THT, and mixed-assembly components. Precise temperature curves and flexible heating profiles reduce oxidation, improve solder joint quality, and lower failure rates.

Panel separation

Gentle separation processes for sensitive assemblies.

Combining multiple panels reduces the handling effort per circuit board. Instead of cutting separation processes, we use machining or laser-assisted separation processes for sensitive components. This prevents microcracks and reliability risks.

Frequently asked questions (FAQ) about THT-Assembly

What is THT assembly?

THT assembly refers to the process of mounting through-hole electronic components, which are inserted through holes in the printed circuit board and then soldered in place. This technology is frequently used for components that are subject to mechanical stress, high-power components, or large-format components.

SE-TEC combines manual THT assembly with wave soldering, selective soldering, and appropriate fixture designs.

What THT soldering processes does SE-TEC offer?

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.

When is selective soldering a good choice?

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.

How does SE-TEC manufacture thermally demanding assemblies?

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.
