[Summary of the Invention 1 That is, the method for drilling holes in a printed circuit board according to the present invention involves inputting a program for drilling along a predetermined pattern to a drilling device, and drilling one side of the printed circuit board based on this program. At the same time, a program is inputted into the drilling device to drill along a pattern corresponding to a mirror image of the pattern, and drilling is performed from the other side of the printed circuit board based on this program. This makes it possible to drill in a predetermined pattern into a printed circuit board that is thicker than the blade length.
