Optimising the selective soldering process improves the quality of the solder joints, enhances process reliability and reduces production costs. In safety-critical sectors in particular, a stable and reproducible soldering process is crucial to the reliability of the assemblies.
Reliable cooling improves process stability, extends the service life of the coil and ensures reproducible results in serial production.
The frequency determines the penetration depth of the induced currents. High frequencies tend to heat the surface, whilst lower frequencies penetrate deeper into the material.
Titanium solder masks limit the effective range of the solder wave and protect sensitive components. They ensure that only specific solder joints are wetted, thereby contributing significantly to process reliability and the quality of the solder joints.
High temperatures can affect materials. Titanium solder masks remain stable due to their low thermal expansion. When used in combination with a suitably matched soldering nozzle, this ensures consistent process conditions and consistent solder joint quality.
Reproducible processes require defined process windows, closed-loop control systems for temperature and solder flow, and continuous process monitoring. In-line systems with a nitrogen atmosphere and validated parameters, such as those used by EUTECT, ensure consistent quality in series production.
Induction soldering generates heat directly within the material through electromagnetic induction. This allows the soldering joint to be heated precisely, whilst adjacent components are spared.
During high-temperature soldering, components and printed circuit boards are subjected to high thermal gradients. Precise control of temperature profiles, heating rates and wetting time is essential to prevent delamination, component damage or insufficient wetting. EUTECT uses validated process windows to ensure stable mass production processes.
Thermally sensitive components such as connectors, sensors or plastic housings benefit particularly from a titanium solder mask. The material acts as a thermal barrier and reduces heat input during mini wave soldering. Titanium masks from EUTECT GmbH are specifically designed for such sensitive assemblies.
A production cell combines several manufacturing steps within a single system. This shortens lead times, reduces transport requirements and improves process control. This results in greater efficiency and better quality.
