Beschreibung
Zusammenfassung:	A defect may occur in which as the amount of fluid discharged by a fluid discharge device decreases, a mask is not filled with the fluid even when the fluid is discharged. In order to fill a workpiece with the fluid, it is necessary to replace air in the workpiece corresponding to a discharge part with the fluid. The air in the workpiece is removed in advance, thereby filling the workpiece with the discharged fluid. A fluid discharge device for applying a fluid into a mask on a workpiece of an electronic component, the fluid discharge device comprising:a head part including a tank capable of containing a fluid, and a discharge head, whereinone end of the discharge head is provided with a suction port for sucking air in the mask on the workpiece, and a discharge nozzle for discharging the fluid,the suction port is installed in an advancing direction of the discharge head,the head part further comprises a heater unit for keeping the fluid in the tank at a desired temperature, andduring preparation for fluid discharge, the discharge head moves closer to the workpiece until the discharge head contacts the workpiece, and during the fluid discharge, air in the mask is sucked from the suction port in a state where the discharge head is in contact with the workpiece, and then the fluid is discharged into the mask.
