7 Your Challenges An industrial inkjet platform demands: - Interface to configurable and different types of print heads - Accurate positioning of print heads - Desired pixel quality - Automated print head startup - Software for full automation Application areas: flat panel display (e.g. RGB colors, hole injection layers) photovoltaic (e.g. active layer, back plane) printed electronics (e.g. RFID, OLED lighting) back-end semiconductor (e.g. PE) Ink/resins development The JetFab 7

8 Interface to (configurable and) different types of print head Wide range of print heads can be integrated: End shooters or recirculating Dimatix, Konica-Minolta, Kyocera, Ricoh, Toshiba, Xaar, Seiko, etc Ink supply designed for non standard (aggressive) inks Number of heads : free configurable 1 up to 10 Print head assembly designed for elevated temperatures Optional: UV pinning 8

9 Accurate positioning of print heads 2 perpendicular axes with in total 3 linear motors to ensure smooth operation. Full mapping of motion system to reduce motion errors to the minimum. Properties Speed range : 0.02 m/s to 0.5 m/s Step resolution : 1 um Position jitter : 2 um Payload on x-bridge : 50 kg 9

10 Desired Pixel Quality The Jetbar is a module with 3 integrated functions. Functions Nozzle check : see if nozzles are clogged or misfiring Pre-spit : at the start of a job print on the jetbar to ensure that the nozzle are open Print head alignment : with a special print image and in house developed software 10

11 Automated print head startup Contactless cleaning of print head Print Head Print Head Assy M Cleaning Head Drip tray Exhaust Pump Vacuum Fluid / Gas Separator Cleaning Fluid Tank Waste 2 step cleaning 1. Wetting the nozzle plate with a flow of cleaning liquid 2. Drying and removing of residual droplets 11

12 Software for full automation Flexibility & full control Properties Unidirectional and bidirectional printing Variable print resolution Changing shuttle speed Interlacing Configurable number and position of swaths Print compensation for substrate expansion possible 12

13 Summary An effective journey from Process Research to a Production Printer is a critical success factor This journey requires an process validation through a pro-production industrial inkjet platform with: Interface to configurable and different types of print heads Accurate positioning of print heads Desired pixel quality Automated print head startup Software for full automation 13
