METHOD FOR SCREEN PRINTING

摘要

PROBLEM TO BE SOLVED: To provide a method for screen printing which can prevent a defective printing caused by curing of a paste. SOLUTION: In the screen-printing method for printing a cream solder 5 on a substrate through pattern holes by sliding a squeegee head 13 on a mask plate 12 by pressuring the cream solder 5 held inside of the squeegee head 13 of a closed type by a pressuring plate 32, the press force to be imposed by press means for pressuring the squeegee head 13 to the mask plate 12 in readiness for printing before print-motion starting is decreased from a press force F2 to F4, then with this condition the press force of the cream solder 5 by a cylinder 16 is increased from a press force F1 to F3. Thereby, the up/ downward motion of the cream solder 5 in the squeegee head 13 is accelerated, and the cream solder 5 is prevented from curing.
