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.
