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