Since the squeegee 3 is moved linearly along the printing direction by the squeegee moving mechanism 4 in a state where the squeegee 3 is in contact with the mask 1 by the printing pressure, the tip of the squeegee 3 is elastic by the printing pressure. Deformation has occurred. In this state, the cream solder 10 is filled in the opening 2 of the mask 1 for printing, so that when the squeegee 3 passes over the opening 2, the deformation of the tip due to the printing pressure is partially restored, and The amount of deformation changes. Therefore, in particular, like the print pattern of the above QFP part, the length of the pattern is parallel to the printing direction (the opening 2 cut by the line XX 'in FIG. 7) and at the right angle (the line YY' is the same). When the squeegee 3 passes through the opening 2 when the squeegee 3 is arranged in each of the cut openings 2), the deformation amount of the tip of the squeegee 3 is parallel to the direction (XX) as shown in FIG. 8A. Since the vertical direction (YY cross section) is larger than the'cross section ', the amount of the cream solder 10 filled in the opening 2 is smaller in the perpendicular direction than in the parallel direction. Therefore, the cream solder 10 printed on the printed circuit board 8 as shown in FIG.
Similarly, the amount of is smaller in the orthogonal direction (Y-Y 'cross section), and even when the size of the opening 2 is the same, the amount of printing varies depending on the directionality of the pattern, and a uniform amount of the cream solder 10 is applied. There was a problem that it was difficult to print.

望ましい。In the printer for cream solder having the above-mentioned structure, the printed circuit board 8 is used in the same manner as the conventional method.
The air cylinder 7 to the mask 1
Thus, the squeegee 3 is brought into contact with the mask 1 with an appropriate printing pressure. In this state, the squeegee 3 is linearly moved along the printing direction by the squeegee moving mechanism 4, and is moved at a right angle to the printing direction by the squeegee right angle moving mechanism 14 in synchronization with the linear movement. After that, when the squeegee 3 moves by a preset distance, the rotation of the motor 12 is reversed. At this time, it is desirable to move the squeegee 3 in the printing direction and the squeegee 3 in the right angle direction at the same speed.

する。By repeating the above operation, the squeegee 3 is moved in parallel to the printing direction and is reciprocated in the direction perpendicular to the printing direction. In this way, the squeegee 3 is reciprocally moved along the screw shaft 13 to fill the cream solder 10 into the opening 2 of the mask 1, and then the printed board 8 is separated from the mask 1 to print through the mask 1. The cream solder 10 is printed on the substrate 8 in a desired pattern.

2, the squeegee moving mechanism 4 moves linearly along the printing direction and the squeegee right angle moving mechanism 14 reciprocates at right angles to the printing direction so that the squeegee 3 moves in the directions of arrow A and arrow A'shown in FIG. The reciprocating movement of the squeegee 3 is synchronized with the movement of the squeegee 3 in the printing direction, so that the movement of the squeegee 3 in the directions of arrow A and A'is alternately repeated.
