摘要:PROBLEM TO BE SOLVED: To provide a method of controlling the quality of the products of electronic components by an electronic component mounting device, which can enhance the quality of the products, mounted on a printed board, for the electronic components by a method, wherein the sucked positions and attitudes of the components are objectively grasped and the electronic component mounting device. SOLUTION: The positions and attitudes of electronic components 15 at the time when the components 15 are sucked from electronic component feeding units 3 using suction nozzles 2 and are held on a printed board 5 are measured by a measuring means 31. When the components 15 are mounted on the printed board 5 by the nozzles 2 in after a required correction is made to the nozzles 2 by a correction means 32 on the basis of the results of the measurements, the individual measured values are kept stored in a memory 33, and a prescribed statistical application is performed on the assembling of these measured values for outputting the result of the statistical application in each electronic component feeding unit 3 by an output means 35, whereby the sucked positions and attitudes of the components 15 can be grasped objectively.
