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 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.

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 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 printer for printing paste on a board by sliding a squeegee head on a mask plate. A pushing plate pressurizes solder paste in the squeegee head, and pressurized paste is led to a paste container from both outer parts in a printing width direction inward towards a printing center through a solder dispensing hole provided on both ends of the paste container. This configuration allows to print in accordance with the time-line supply sequence, regardless of the printing width of the board to be printed. This screen printer thus prevents the degradation and the consequent need for disposal of solder paste due to its retention in the squeegee head for long periods.

摘要： A screen printing method and apparatus are capable of maintaining a constant attack angle between a squeegee and a mask plate, regardless of the surface condition of the mask plate. A squeegee head, including a pair of squeegees, is rotatably supported by a retainer with respect to a horizontal axis that is at a right angle to a squeegeeing direction. The rotatably supported squeegee head is pushed by a cylinder against the mask plate. Accordingly, the attack angle is kept constant to improve the printing quality even if a substrate has a curved portion.

摘要： It is possible to obtain a screen printing apparatus and a screen printing method wherein a high pressing force is not required to print paste on a substrate thereby assuring reliable printing qualities. In the screen printing apparatus which prints the paste on the substrate through pattern holes, the paste in a storage section is pressurized and forced out of a printing space portion through a transfer passage. The paste is given a rolling motion while it is guided by rolling guide surfaces disposed at the printing space portion, and then, the paste is filled into the pattern holes from a printing aperture formed by two scraping members.
