Abstract
A screen printing apparatus is designed so that cream solder 17 disposed on a mask plate 12 can be preserved at a certain appropriate temperature by the limited use of blown air. An air nozzle unit 20 is provided above the mask plate 12 at a place on the side edge running in parallel with the moving direction of a squeegee 16. The temperature-conditioning air is blown sidewise from the air nozzle unit 20 towards the cream solder 17 during the operation of printing the cream solder 17 on the surface of a substrate through the mask plate 12 disposed in contact therewith.
