EN-Square Wave-data sheet 10/8/13 10:06 AM Page 1 Square Wave™ 745NC Non-Contact Dispense Valve The Square Wave 745NC high speed non-contact valve applies lowviscosity water soluble and solvent-based liquid fluxes in accurate, repeatable amounts on cell bus bars and solder-coated ribbon used in cell string attachment. Features • High speed capability – innovative solenoid technology delivers cycle rates up to 500Hz • Actuation speeds as low as 2 ms • Compact design • Light weight and easy end-of-arm installation • Low-maintenance design • Small wetted path minimizes fluid waste • Volume output as small as 0.15µL • Adjustable fluid flow • Positive shutoff Benefits • Non-contact dispensing eliminates need for Z-axis motion • Less frequent replacement, less downtime, lower maintenance costs • High production throughput and yield • Easy to service • Integrated solenoid minimizes process variation • High cycle speed creates dot-to-dot “stitching” that flows together to form a continuous line
