<P>PROBLEM TO BE SOLVED: To identify a cause efficiently, without deteriorating the productivity of a substrate as much as possible, when packaging failure occurs. <P>SOLUTION: In a method of identifying the cause of packaging failure in a packaging line, where a screen printer 2, mounting machines 3-5, and an inspection machine 6 form a line, a packaging place on the substrate, in which the packaging failure is detected in the inspection machine 6 is set to be a target point, and one of the screen printer 2 and the mounting machines 3-5 for working the target point is set as the target machine. After the packaging failure is detected, the image of the target point of a subsequent substrate carried in the target machine is captured, at least at one of periods before and after the work to the point, and the cause of the packaging failure is checked, based on the captured image. <P>COPYRIGHT: (C)2008,JPO&INPIT |
