Patent ID: 7506434

Claim:
An electronic parts mounting method of picking up a plurality of electronic parts simultaneously by a transfer head having a plurality of suction nozzles from a plurality of tape feeders aligned in parallel in a parts feeding portion and having tape feeding mechanisms to feed the electronic parts held on tapes to parts suction positions of the suction nozzles, and then mounting the electronic parts on a substrate, comprising: a correction data generating step of generating stop position correction data to correct parts stop positions of the tape feeding mechanisms; a correction data storing step of storing the stop position correction data in a correction data storage; a registering step of controlling the tape feeding mechanisms based on the stop position correction data read from the correction data storage to mate the parts stop positions with the parts suction positions; a stop position detecting step of detecting parts stop positions at which the electronic parts fed by the tape feeding mechanisms are stopped, wherein the stop position correction data are generated in the correction data generating step based on stop position detection results; and a nozzle displacement detecting step of detecting displacements of respective suction nozzles in the transfer head, wherein the stop position correction data are generated in the correction data generating step in light of nozzle displacement detection results detected in the nozzle displacement detecting step.
