Abstract
In the process of forming a through-hole or blind-hole at desired positions of a the substrate material, the present invention sets a drilling target position for each hole and a plurality of auxiliary drilling positions at a periphery of the drilling target position, and performs a plurality of drillings at the drilling target position and the plurality of auxiliary drilling positions. In another preferred embodiment of the present invention, a plurality of drillings are performed only at the auxiliary drilling positions per one hole at the desired position. According to the present invention, through-holes or blind-holes having several sizes of diameters can be formed by using one drilling jig under a single drilling condition. Accordingly, it is possible to efficiently produce circuit boards at low costs.
