摘要： In a screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate, a predetermined measuring position of the mechanisms in the screen-printing apparatus is measured three-dimensionally by a three-dimensional measuring device. Based on the measured result, a predetermined measuring point on an object to be measured is determined on a position relative to the origin of the mechanical coordinate system in the screen-printing apparatus, and the origin position on a control program can be set. As a result, machine adjusting operation and teaching operation in the screen-printing apparatus can be simplified with high accuracy.

摘要： A squeegee head having a volume-variable container and a printing space is used. The volume-variable container is variable in capacity with pressures applied thereto. The volume-variable container includes a projecting portion having a plurality of projections, a push-plate with a plurality of through-holes formed therein, and a side wall. A paste is stored in the volume-variable container. The projecting portion is pressurized to move and the paste is pushed out into the printing space from the through-holes, and then, the projections are fitted into the through-holes. In this way, the paste being stable in viscosity is completely pushed out into the printing space without wasting at all.

摘要： A screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate. A laser-measuring device mounted in the apparatus measures the top surface of the screen mask at a printing position and the top of the substrate at a substrate-measurement position by three-dimensional measurement, and detects a shape of the substrate or the screen mask, and determines whether or not they are acceptable. After screen printing is completed, the substrate and the screen mask undergo a printing inspection where their shapes are inspected. This provides not only inspection data of the printing results but also data for identifying the causes of print failures. As a result, the screen-printing apparatus, which has high-printing accuracy and can prevent printing failures from occurring, is provided.

摘要： A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. The mask plate, to which the substrate is positioned, is three-dimensionally measured from its above, thereby detecting a positioned status. Based on the detection result, the positioned status is corrected by driving a substrate-positioning-section. As a result, the substrate is always exactly positioned to the mask plate, and quality print is thus maintainable.

摘要： 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.

摘要： A screen printing apparatus prints cream solder through a pattern hole of a mask plate, to which a substrate is brought into contact, by sliding a squeegee head. A three dimensional detector, such as a laser, is used to determine the extent to which the pattern hole is filled with the cream solder. Based on the determination result, the printing operation is modified, with respect to the positioning of the mask plate and substrate, to maintain the printing quality.
