Electronic parts mounting on printed circuit board

A method of mounting electronic parts on the predetermined position of a printed circuit board is capable of simultaneously correcting the mis-registration of electronic parts by one cycle of operations so as to precisely position and mount the parts on the PCB. The misregistration of individual electronic parts with respect to suction tubes of a suction head in the apparatus is corrected 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 centre of each of the parts with that of the corresponding suction tube.
