Rehm at IPC APEX EXPO 2025

True to this year's motto 'Reimagine the Possibilities', Rehm Thermal Systems has driven forward the further development of its system solutions in the areas of condensation soldering, coating and dispensing and found new approaches for more economical vapour phase soldering and more flexible automated coating and dispensing applications.

At its company booth, Rehm experts will be demonstrating the wide range of applications live on the ProtectoXC, its dispensing and coating system, and will inform visitors about the more economical vapour phase soldering with the Condenso Series thanks to the integrated closed-loop system.

Conformal coating has become an integral part of modern manufacturing, as the protective coating is used to reliably protect electronic assemblies from aggressive environmental influences. With the Protecto Series, Rehm Thermal Systems offers a system that is not only used for automated coating, but also for bonding, sealing and fixing:

With the applicators for the Protecto systems, users can apply up to four different materials 'on the fly' directly. The systems can be operated using the ViCON Protecto software, which fulfils all the requirements of modern, networked and, above all, future-oriented electronics production: intuitive and user-friendly operating elements make it quick and easy to create painting images. It is also easy to access the software with different devices.

Soldering under vacuum has been a proven technique for decades in vapour phase soldering systems to significantly reduce air inclusions in solder joints. With the closed-loop system for the injected Galden medium integrated in the vapour phase soldering systems of the Condenso Series, Rehm Thermal Systems has found a future-proof solution for more economical vapour phase soldering:

After soldering, the vacuum and/or cooling process begins. At the same time, the process gas is extracted and purified. A vacuum is created during extraction, which guarantees rapid drying of the solder and process chamber, therefore minimising losses when the products are discharged. The extracted Galden is filtered and cleaned of impurities using granules. This allows approx. 99.9% of the medium to be recovered. The purified liquid is stored in a container at room temperature and made available for further processes. This means that no evaporation and energy losses occur. The hermetic sealing of the process chamber (also a vacuum chamber) also prevents evaporation losses during soldering.

The closed-loop system of the Condenso Series effectively supports more economical vapour phase soldering with lower production costs thanks to lower Galden consumption, minimal maintenance and fewer production errors.
