PURPOSE:To reduce the number of discrimination processes and a display error by providing the following: a discrimination-mark-pattern formation stage; the learning stage of a mounting machine; and a discrimination-mark-pattern display stage. CONSTITUTION:At a discrimination-mark-pattern formation stage 1, discrimination marks for the kind of printed-circuit board, its lot, its manufacturing date and time and the like are formed in parts other than circuit patterns. At the learning stage 2 of a mounting machine, a program by means of which inessential parts on discrimination-mark-patterns are coated with only an adhesive is input in the input process of the coating place of the adhesive when a prescribed chip component is mounted on the coated part. Then, at a discrimination-mark-pattern display stage 3, inessential parts on discrimination- mark patterns are coated with an adhesive in the coating process of the adhesive by using the mounting machine, and only required discrimination-mark- patterns are left. Thereby, when a display for discrimination use is performed on the printed-circuit board, the number of discrimination and display processes and a display error can be reduced. |
