PICO™ Jet Dispensing Systems Nordson EFDʼs new PICO non-contact dispensing systems combine high production speed with exceptional deposit accuracy and process control. By jetting droplets of fluid onto the product, the time-consuming need to move the valve to the substrate is eliminated. Fluid can be dispensed into difficult to access areas and onto uneven or other substrates where a dispense needle cannot contact the substrate. Features • Ideal for use on uneven substrates or hard-to-access areas • Consistent shot size, with droplets starting at 0.002 μl (2 nl) to flow rates up to 300 g/min (10 oz/min) • Continuous operation at 150 cycles/second (H2) • Compatible with a wide range of low to high viscosity fluids Benefits • Eliminates Z-axis movement and need for precise height positioning, for significantly higher dispensing speeds • Outstanding process control for highest dot-to-dot consistency and best process capability • Reduces downtime and scrap by eliminating risk of substrate-nozzle collision • Fast change-over without need for any process readjustments • Integrated heater in the valves, a choice of different nozzle orifice sizes and precision needles allow optimizing the dispensing process for a wide range of fluids Specifications Low Viscosity Valve (LV) Dimensions Weight Cordset Medium Viscosity Valve (MV) High Viscosity Valve (HV / PV) 72 X 14 X 60 mm / 2.8 X 0.6 X 2.4" (without needle adapter) 290 grams / 10 oz Acceptable Fillers in Fluid Examples: various oils, alcohol, octane, and organic solutions 50-1,000 mPas / 50-1,000 cps (thixotropic) None Materials in Contact with the Fluid Viton, Perfluoroelastomer, stainless steel 303 / 1.4305 Min.
