PROBLEM TO BE SOLVED: To provide a method for screen printing capable of surely correcting and holding a printed circuit board by a suction block even for a case when a high density assembling is performed, and decreasing vertical vibration of a screen when a printing plate is released. SOLUTION: The printed circuit board 2 is supported by delivering parts 24a and 24b and are carried in at a printing position, and the arrived work is lifted up from the delivering parts and the delivering parts are retreated. The underside of the printed circuit board 2 including parts supported by the delivering parts is sucked with a wider width W2 than before by the suction block 4, and is corrected and held, and the printed circuit board 2 under the corrected and held condition is screen-printed with a solder paste. In addition, when the printed circuit board 2 is separated from the plate face part of the screen (b), it is separated therefrom by sucking and holding the screen 6. COPYRIGHT: (C)2005,JPO&NCIPI
