Abstract
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.
