Drying UV coatings for short cycle times

The electronics industry is also increasingly turning to UV coatings. With the RDS UV Dryer, Rehm has provided a system that has been tailored to the requirements of drying UV coatings.

Declining cycle times during the coating process today require faster hardening times, which can be implemented with the help of UV drying systems. Rehm Thermal Systems has responded to this trend by developing the new RDS UV Dryer, which is a system that has been specially designed for hardening UV coatings and UV adhesives with very short cycle times. 

With the RDS UV, Rehm provides a flexible and reliable dryer that makes the hardening process for UV coatings straightforward. Thanks to a short heating phase of just a few seconds, the system is immediately ready for use and is therefore reportedly more efficient than comparable systems in terms of energy use. 

In order to achieve increased cycle times, the RDS UV Dryer has been optimised with a three-part transport system. This means that two assemblies can be processed in the furnace at the same time and that the 100% traceability of any circuit board continues to be guaranteed. Furthermore, the dryer is equipped with four-compartment technology, which guarantees that harmful UV radiation can never escape. 

Thanks to its compact structure, the RDS UV Dryer can be adapted flexibly to production landscapes. The UV process can be equipped with various light sources according to the customer’s wishes. 

Available options include undoped mercury medium pressure lamps, doped UV lamps, UV LED fields or special lamps with specific light spectrums. This ensures flexibility, as well as efficient and economical production.
