PROBLEM TO BE SOLVED: To improve the production efficiency in an automatic mounting stage by that individual printed boards on both main surfaces of a both-side component mounting printed board have the same constitution. SOLUTION: Individual printed boards on one and the other main surfaces 101, 101' of a two-board type both-side component mounting printed board have the same constitution, and hence identical manufacturing jigs and programs for the one main surface of the two-board type board are used for manufacturing them. Thus, the time taken for manufacturing on both main surfaces 101, 101' of the two-board type board is averaged, the indexing time for the manufacturing preparation in an automatic mounting apparatus is reduced half to improve the equipment availability in the automatic mounting process. After mounting components 102, 103 on the main surface 101 of the two-board type board, components 102, 103 are mounted on the other main surface 101' in the same or equivalent process, and hence the production efficiency in the automatic mounting process can be improved. |
