Abstract
A method of applying a bonding paste efficiently and uniformly by discharging the bonding paste from an application nozzle is presented. For applying the paste along a drawing pattern including a cross shape pattern composed of crossing plural application lines, the nozzle moves from the center of the cross shape to an end point along one application line, turns to a reverse direction at the end point, and moves to an end point at opposite side of the application line. Then, the nozzle returns from the end point to the center of the cross shape. The nozzle repeats this unit application line drawing operation for each application line. As a result, the nozzle stops less frequently near the center, has a shortened cycle time, and applies the paste uniformly.
