摘要： A screen printing apparatus in which a squeegee head 13 is moved on a mask plate 12 thereby to print paste on a substrate through pattern holes 12a, slide contact portions 37A and 37B form respectively front and rear walls in the squeegeeing direction of a printing space 35 which reserves cream solder 5 therein and makes the cream solder contact with the surface of the mask plate 12 through an opening portion formed at the lower surface thereof. Each of the slide-contact portions is configured by a partition plate 39 for partitioning between the printing space 35 and the outside and a filling block 38 having a filling surface 38a which forms an acute angle with respect to the surface of the mask plate 12. In the squeegeeing operation, the filling surface 38a rolls the cream solder 5. Thus, the cream solder 5 can be filled into the pattern holes 12a without pressurizing the cream solder, and a problem caused by the leakage of the cream solder can be eliminated.

摘要： Cream solder stored in a squeegee head is pressurized by a pressurizing plate, and the squeegee head is slid on a mask plate, so that the cream solder is printed onto a substrate via pattern apertures. This is done by a screen printing apparatus, in which pressurized solder is accommodated, and the solder is brought into contact with a surface of the mask plate via an opening formed on a lower face of the cell. A rectifier is disposed in the cell for blocking the cream solder from flowing into a specific area just above the opening. This structure allows the solder to flow into the opening in a slant direction, and causes the solder to roll. This mechanism prevents the solder from being hardened due to staying stagnant just above the opening, and thus prevents defective printings.

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.
