ABSTRACT:
A dummy work (DW: a work for printing a reference necessary for subsequent printing) is moved to a printing position while the dummy work is fixed to a work alignment mechanism2, and solder printing is made. The printed dummy work is then returned to the work alignment position and its image is taken by image processing cameras7and an image of position coordinates of a solder bump specified for alignment is stored. Positioning of subsequent works W is conducted on the basis of the image of the dummy work stored and solder printing of the works is subsequently made at the printing position.
