MB Getter Dispenser Platform

The MB-GDP is a versatile multi-purpose platform which in its most frequently used setup is applied as part of the encapsulation of OLEDs. In the standard established OLED encapsulation process the consecutive application of desiccant materials and UV curing adhesives is utilized in order to seal and protect sensitive organic materials from the harmful interaction with ambient conditions, especially moisture.


Unlike other system concepts in which both process steps are segregated from each other, the MB-GDP follows a combined approach. Dispensing and getter mounting are integrated in the same platform allowing for a minimized footprint, significantly reduced investment costs and still offering an unmatched flexibility for future extension and upgrades.


A variety of dispensing valves ranging from pressure-time-valves, over micro-screw volumetric dispense heads up to high-velocity jetting units offers solutions for any kind of dispensing task. The integrated multi-purpose head holds space for up to 5 different process units so that even an ODF-process (One Drop Filling) with a combination of jetting valve and volumetric valve becomes possible.


In the standard setup a pick-and-place vacuum suction head with an automatic feeding system is embedded allowing pasting desiccant sheets (getters) of various sizes onto the cover glass.


Integrated into the multi-purpose head is a CCD camera which verifies the position of the cover glass on the stage, monitors the correct placement of the desiccants and supervises the precision of the dispensing.


Being available as a stand-alone unit and embedded into a fully-automated line the MB-GDP fulfills all requirements of process stability and accuracy from sophisticated research up to pilot scale manufacturing.
