Screentec Oy is a Finnish contract development and manufacturing company for printed electronics. During the past ten years company has moved from manufacturer of user panels for domestic markets to a supplier of custom medical electrodes to customers around the world. This presentation will give insight of the journey from first prototyping to continuous production of several medical electrodes.

1. Introduction Schepers GmbH & Co KG and Heliograph Holding; 2. Introduction of the Digilas ultra high Cylinder Processing system; 3. Possibilities in cylinder direct micro structuring by ultrashort pulsed lasers; 4. Opportunities in the engraving of gravure cylinders for the electronic printing; 5. Examples of rotogravure applications served by the Digilas engraving system; 6. Summary

We describe the fundamentals of the DPP technology and focus unique process advantage over etching, namely the adjustment of the depth-of-cut in the milling process. By cutting deeper or shallower into the flex PCB foil, the milled pattern can be modified by up to 100 µm in line width. Control systems keep the process precisely at the selected level within an extremely precise 100 nm accuracy.

We demonstrate the challenge to go from lab-scale to industrial scale to achieve highly efficient fully inkjet printed IOPV cells and module for indoor application.
