ABSTRACT:
A screen printing apparatus for printing solder paste onto a surface of a printed circuit board through the medium of a screen having openings. The apparatus includes a solder paste automatic supply dispenser of a nonflexible box-like structure which is arranged to be displased along a pair of guide rails back and forth and to be raised and lowered relative to the guide rails. The dispenser has a chamber for containing solder paste to be printed on the surface of the circuit board and an adjusting device attached to the dispenser for adjusting the temperature of the solder paste contained in the chamber so as to be capable of maintaining the temperature at a predetermined degree. The chamber is provided, at a bottom potion thereof, with a slit-like aperture extending normal to the direction of travel of the dispenser and arranged to be normally closed and to be kept open to automatically supply a predetemined amount of the solder paste contained in the chamber onto an upper surface of the screen during printing. The aperture is provided, at its rear edge portion, with a squeegee blade extending along the entire length of the aperture and being adapted to be kept in contact with the upper surface of the screen at its lower end during printing.
