Nordson 3-Axis Pro4 Dispensing Robot with precision stage (±3 µm repeatability) with custom heated vacuum chuck (-120 ˚C to +200˚C) and integrated laser for z-height mapping to maintain consistent nozzle-to-substrate distance (within ±1 µm). Fluid flow is controlled using an Elveflow OBII MkII Microfluidics Controller with microfluidic flow sensors accurate to 0.01% for flows up to 80 µL/min. This printer is used to metallize photovoltaic cells using reactive inks.
