PROBLEM TO BE SOLVED: To provide a screen printing apparatus reducing an amount of cream solder to be discarded, and also to provide a squeegee mechanism. SOLUTION: Each of the squeegee mechanisms 11 and 12 has a main squeegee 13 and a pair of auxiliary squeegees 14 and 15 provided at both width direction ends of the main squeegee 13. The whole auxiliary squeegees 14 and 15 are arranged on the back side of the sliding direction of the main squeegee 13, and they are tilted a predetermined skew angleθwith respect to the main squeegee 13. The outside ends 14a and 15a of the auxiliary squeegees 14 and 15 are disposed more on outer sides than the ends 13a and 13b of the main squeegee 13. Their inside ends 14b and 15b are disposed more on inner insides than the ends 13a and 13b of the main squeegee 13. By the auxiliary squeegees 14 and 15, cream solder 4 that has leaked sideways from the end portions of the main squeegee 13 is returned to an inner side of the screen 1 and circulated. As a result, the amount of cream solder 4 to be discarded is reduced. COPYRIGHT: (C)2011,JPO&INPIT |
