Abstract
Predetermined NC data for inspection including data of a predetermined location of an electronic component to be mounted on a PCB is stored in a microcomputer. A signal representing the image of the PCB on which no electronic component is yet mounted is obtained by using a television camera. From the obtained image signal of the PCB, the patterns of pads for mounting electronic components on the PCB is extracted. On the basis of the extracted pad patterns, the optimum location of the electronic component to be mounted is specified. The NC data of the electronic component location which is stored in the microcomputer is corrected according to the result of the specification.
