Abstract:
A method for dispensing a plurality of droplets of viscous liquid material in sequence with each droplet tending to separate into a droplet and at least one satellite portion during flight toward a substrate using a dispenser having a liquid discharge passageway in fluid communication with a source of viscous liquid and an air discharge passage in fluid communication with a source of pressurized air, comprising:dispensing the plurality of droplets of viscous liquid in sequence from the liquid discharge passageway in a travel path substantially transverse to the substrate;discharging pressurized air as a sheath from the air discharge passage in a direction substantially parallel to the travel path of the droplets; andsubstantially surrounding each dispensed droplet and the satellite portion associated therewith with the discharged sheath of pressurized air during flight toward the substrate so that the satellite portion is contained within the sheath of pressurized air.
