Together with a number of partners like Limo Lissotschenko Mikrooptic GmbH, 4JET Technologies GmbH, Ruhr Universität Bochum and Fraunhofer Institute for Laser Technology, Coatema finished the NRW (North Rhine-Westphalia) Ziel 2 funded project Flexlas. The target was to develop a laser patterning process for OPV devices, which also later can be applied to other products like OLED lighting.
In the project, Coatema’s task was to develop a universal lab unit for OE processes and to integrate a laser source and optics provided by the partners. The prototype system developed is based on Coatema´s proven Smartcoater technology, which is now based at the Fraunhofer ILT in Aachen. The Smartcoater as a dedicated unit for printed electronics allows operating under nitrogen atmosphere and is a cost effective approach to stabilize the web under different laser sources.
Coatema integrated R2R laser systems with more than five industrial and R&D partners. The next step is to introduce the laser patterning developed into complete inline processes for organic or hybrid systems. Additional funded projects would be needed to support the scale up process into a working width of 1.000 mm with a higher resolution and registration accuracy.
Out of this project Coatema Coating Machinery GmbH was able to install more than five industrial or R&D systems in Europe.
“The Flexlas project once more demonstrated the innovation and development potential of North Rhine-Westphalia,” said Caotema VP Thomas Kolbusch.
