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： 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.

摘要： A screen printing apparatus and method suitable for applying solder paste on a printed circuit board, wherein a printed circuit board is brought just under a mask plate with patterned holes. The patterned holes are filled with solder paste. The printed circuit board is separated from the mask plate using intermittent movements that lower the adhesivity of the solder paste located nearest to the walls of the patterned holes so that the solder paste is easily separated from the patterned holes and the solder paste, which remains on the printed circuit board, is not deformed.

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： 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.
