テーブルは、元の位置に戻り次の印刷すべき基板
10の載置を待つ。 The operation of the above configuration will be explained below. First, the substrate 10 placed on a conveyor (not shown) is conveyed and reaches a position below the screen printing machine 13. A table is raised by a cylinder (not shown), and after placing it on the substrate 10, it is placed on the table. Adsorb. After suction, the table moves to the printing station, and the table further rises to bring the substrate 10 close to the screen 11. Then, the forward printing squeegee 14 moves to the right while pressing against the screen 11 by the cylinder 30. Therefore,
Cream solder 12 is applied onto the substrate 10 through holes made in the screen 11. At this time,
Since the outward protrusion of the cream solder 12 caused by the running of the squeegee 14 is prevented by the side walls 17 and 18, the frequency of replenishing the screen 11 with the cream solder 12 is reduced. When forward screen printing is completed, the forward printing squeegee 14 is raised by the cylinder 30, and after releasing the adsorption of the substrate 10, the table is lowered, and the substrate 10 is placed on a conveyor (not shown) and moved to the right. transport. The lowered table returns to its original position and waits for the next substrate 10 to be printed.

る。 Regarding the printing operation for the next substrate 10, the conveyance operation and the like are the same as those described above, so a description thereof will be omitted. As described above, when the substrate 10 approaches the screen 11, the reprint squeegee 31 is lowered by the cylinder 44 and travels to the left in FIG. 1 to perform printing.

るものである。 Note that the stepped portions 1 of both side walls 17, 18, 33, and 34
The longer the polymerization width by 9, 20, 35, and 36, the larger the amount of cream solder 12 that is the coating material can be, and the administrator of the screen printing machine 13 can save time and effort in replenishing it. Further, the height of the squeegee 14, 31 can be adjusted depending on the amount of deflection when the squeegee presses against the screen 11 and the viscosity of the cream solder 12.
Loosen holes 4, 39, and 40 to install mounting hole 2, which is a vertically long hole.
1, 22, 37, and 38. That is, when the viscosity is low, if the lower ends of the squeegees 14, 31 are prevented from protruding from the side walls 17, 18, 33, 34 as much as possible, the cream solder 12 can be prevented from protruding outward from the squeegees 14, 31. It is something that will be done.

すことができる。 Furthermore, in the case where a solder return scraper is provided in place of the reprinting squeegee 31 and the cream solder 12 is returned to its original position by the scraper after printing with the squeegee, the present embodiment is applied to both sides of the scraper. By providing both side walls 33 and 34 as shown, the cream solder 12 can be reliably returned to its original position.

I can figure it out. In addition, unlike conventional methods, if the properties of the overflowing coating material and the newly replenished material differ, variations in quality may occur, and furthermore, in order to eliminate this variation, it is necessary to mix the two well before use. However, according to the present invention, such a problem can be solved.
