  • Fluid dispenser with low surface energy orifice layer for precise fluid dispensing
    Patent number: 9427734
    Abstract: The present invention is embodied in a method for precisely dispensing fluid, including treating an orifice of a fluid dispensing apparatus during a fabrication process by applying a low surface energy material layer onto the orifice, adjusting a thickness of the low surface energy material coating to a predetermined threshold and limiting backpressure of a low dead volume fluid delivery system coupled to the orifice to reduce interference or interruptions for precisely dispensing the fluid.
    Type: Grant
    Filed: June 1, 2009
    Date of Patent: August 30, 2016
    Assignee: Hewlett-Packard Development Company, L.P.
