Abstract
A method of controlling edge definition of viscous material applied to an application area on a substrate comprises dispensing a row of droplets of the viscous material onto the application area with a dispensing apparatus. While moving relative to the substrate along a path proximate the row of droplets, the dispensing apparatus dispenses a fan spray pattern of the viscous material. At least some of the viscous material dispensed in the fan spray pattern impinges and mixes with the row of droplets to define an edge of the fan spray pattern.
