    摘要: A printing operation is repeatedly performed with respect to one substrate 2, the printing operation including the step of loading the substrate 2 (the step ST1), then contacting an upper surface of the substrate 2 with a mask 13 (the step ST4), reciprocating a squeegeeing operation to slide squeegees 33b on the mask 13 in contact with the substrate 2 to transfer a paste Pt on the mask 13 to the substrate 2 (the step ST7 and the step ST8), separating the substrate 2 from the mask 13 for a snap off (the step ST9), and while unloading the substrate 2 (the step ST11), performing mask cleaning to remove the paste Pt that is adhered to a lower surface of the mask 13 (the step ST12).

    摘要: Pattern holes are completely filled with paste. As a result, occurrence of defects is prevented, and an excellent printing performance is obtained, high speed screen printing is possible, and the printing efficiency is enhanced. By sliding in the running direction above the mask plate having pattern holes, this squeegee for screen print can print the paste supplied on the mask plate to the substrate through the mask plate. It includes a contacting portion for contacting with the surface of the mask plate, a filling portion disposed at the running direction side of the contacting portion, and an agitating portion disposed at the running direction side of the filling portion. The agitating portion has a function of rotating the paste by sliding. The filling portion has a function of filling the pattern holes with the paste along with the sliding motion. The paste applied in the pattern holes can be printed on the substrate.

    摘要: A component mounting method includes: identifying, by image processing, a dark color region from image data obtained by imaging a two-dimensional region including a pickup face of a component to be picked up; deriving position data indicating a position of the identified dark color region; and deriving, based on the derived position data, a pickup position indicating a position at which a nozzle picks up the component. The imaging is performed by an imaging unit, and the dark color region indicates a dark color portion between electrodes of the component.

    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 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 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.
