Abstract
A liquid material dispensing system includes a nozzle tip that is adapted to dispense droplets of liquid material that expand in flight toward a substrate. The droplets elongate in orthogonal directions in a plane that is substantially transverse to the direction of travel of the droplets toward the substrate. Preferably, each droplet elongates in pattern width and in pattern length during its flight toward the substrate. The elongated droplets impact the substrate and contact adjacent droplets to form a generally rectangular layer of liquid material within a predetermined area on the substrate. Methods for forming a generally rectangular layer of liquid material on a substrate are also disclosed.
