All components are engineered to work together as a complete, integrated system that produces exceptionally fast, accurate deposits of a wide range of fluids. Features and Benefits • Continuous operation up to 500 cycles/second (Hz) permanent • Consistent shots as small as 0.5 nanoliters • Ideal for hard-to-access or uneven substrates • Non-contact jetting systems eliminate Z-axis movement for significantly faster production speeds • Configurable for high-speed needle dispensing • Compatible with a wide range of fluids • Slider valve systems available for solder pastes and other filled material (slider valve cycle rate only 10Hz permanent) Jet Valves (for Non-contact Dispensing) PICO jet valves incorporate two piezoelectric actuators composed of stacked ceramic coins that expand and contract in response to changes in voltage supplied from the valve driver. Both actuators are connected to a vertical rod with a wear-resistant ceramic sealing ball at its lower end. When the valve is closed, the ball is seated in the valve nozzle plate. When voltage is applied to the actuators, the rod and sealing ball are raised so that the pressurized fluid can flow to the nozzle. When the voltage is changed, the rod and sealing ball descend rapidly to “jet” the fluid out of the nozzle and onto the substrate. The extremely fast action of the piezoelectric actuators makes it possible to dispense fluid continuously at speeds of up to 500 cycles per second. Depending on the fluid, the system can produce consistent shots as small as 0.5 nanoliters.
