ABSTRACT:
A method of mounting electronic parts on the predetermined positions of a printed circuit board is disclosed which is capable of simultaneously correcting the misregistration of a plurality of electronic parts by one cycle of operations so as to precisely position and mount the electronic parts on the printed circuit board. In the present invention, the misregistration of individual electronic parts with respect to suction tubes of a suction head in an automatic chip-mounting apparatus is corrected at the time when the suction tubes suck up the electronic parts from the cavities of the jig in which the electronic parts are charged to thereby place each of the suction tubes on the predetermined or exact suction position of the electronic parts or align the center of each of the electronic parts with that of the corresponding suction tube.
