Abstract
An apparatus and method for dispensing one or more liquid beads on a substrate utilizes a liquid dispenser with one or more liquid dispensing outlets and one or more movable electrostatic point sources. Liquid material dispensed from an outlet is attracted to, or otherwise electrostatically influenced by, the electrostatic point source(s) resulting in controlled placement of the liquid material on a substrate passing or positioned between the outlet(s) and the point source(s).
