Abstract
A liquid material dispensing system includes a nozzle assembly that is adapted to dispense a droplet of liquid or viscous material, such as solder flux or adhesive, onto a substrate. The nozzle assembly includes a liquid discharge passageway for dispensing the droplet, and an air discharge orifice for discharging a sheath of pressurized air. The sheath of pressurized air substantially surrounds the dispensed droplet and any satellite portions associated therewith during flight toward the substrate. The sheath of pressurized air advantageously contains the satellite portions within the discharged sheath to prevent them from falling onto areas of the substrate where it is undesirable to have a coating of liquid or viscous material. Methods for dispensing a droplet of liquid or viscous material onto a substrate are also disclosed.
