Description
Square Wave™ high-speed, non-contact dispense valve applies controlled amounts of liquid flux on cell bus bars and solder-coated ribbon used in the photovoltaic and other industries. Used in cell string attachment, the innovative integrated solenoid technology allows it to connect PV wafers at cycle rates up to 500Hz with volume output as small as 0.15 µl and minimizes process variation. Features a lightweight, low-maintenance, compact design for easy end-of-arm installation. Eliminates the need for Z-axis motion. High cycle speeds create dot-to-dot “stitching” that flows together to form a continuous line. Actuation speeds as low as 2 ms. Small wetted path minimizes fluid waste. Adjustable fluid flow. Positive shutoff.
