PROBLEM TO BE SOLVED: To solve a problem that surface mounting components and insertion mounting components are mounted in different steps when both of the surface mounting components and the insertion mounting components are mounted on a printed circuit board.SOLUTION: A manufacturing method of a printed circuit board includes: a step where a metal mask, in which openings are disposed at positions corresponding to lands and through holes formed on a printed circuit board, is placed on the printed circuit board; and a step where a solder paste is applied to surfaces of the lands and inner parts of the through holes through the openings.SELECTED DRAWING: Figure 1 |
