ABSTRACT:
A method and apparatus for detecting and enabling correction of a failure in the mounting of electronic parts on substrates, capable of automatically and efficiently accomplishing the detection of a failure in the mounting of electronic parts on substrates, and classification between failed substrates and acceptable substrates to improve the overall operation efficiency of an electronic parts mounting line. The method is adapted to apply a code mark to each substrate on which electronic parts are to be mounted, detect a failure the mounting after, read and store the code marks and failure data of failed substrates, and classify the failed substrates from acceptable substrates and transfer the failed substrates on the basis of the code marks and failure data stored.
