摘要： PROBLEM TO BE SOLVED: To provide a method for screen printing in which a driving apparatus is simpler than the conventional one, and even when a printed circuit board for high density assembly is repeatedly printed at a high speed, time for adjusting it can be shortened.
SOLUTION: Printing is performed by moving a squeegee head 10 back and forth, and a viscous body 4 at a finishing position of the printing is recovered and returned to a starting position of the printing by using a set of a squeegee 11 for filling and a squeegee 12 for scraping used for the printing, and additionally, a squeegee 13 for pushing-in. As the printing is performed only one way like this, fluctuation of printing result which has been generated before is solved, and as the viscous body 4 is recovered and returned to the starting position of the printing by using a set of the squeegee 11 for filling and the squeegee 12 for scraping used for the printing, the driving apparatus becomes simple.

摘要： PROBLEM TO BE SOLVED: To form a stable print film even when physical properties of paste is changed by detecting the properties of the paste supplied onto a screen mask, calculating squeegee sliding conditions for sliding a squeegee on a screen mask according to a detected value, and driving the squeegee according to it. SOLUTION: A squeegee 3 is held by a squeegee holder 6, and moved on a guide rail 7 according to a command signal from a controller 9 in a direction of an arrow. A base plate support table 8 holds the plate 2 to be printed on its upper surface. A pressure sensor 10 is mounted on the surface of the squeegee 3 to a front side to its moving direction, and disposed so that in the case of moving the squeegee 3 by supplying cream solder to the surface of a screen mask 1, its measuring surface is brought into contact with the supplied solder. When the squeegee 3 is moved while pushing the solder on the mask 1, the viscosity of the solder can be obtained from the pressure of the solder.
