Abstract:
1. A method of manufacturing a circuit board, said method comprising: setting a target position at a drilling position of a substrate material; setting a plurality of auxiliary drilling positions at a periphery of the target position; and performing a plurality of drilling operations at the plurality of auxiliary drilling positions to form one of a through-hole and a blind-hole at the drilling position, wherein the drilling operations at the plurality of auxiliary drilling positions are performed using an energy beam, wherein the energy beam is applied to the substrate material by one of a collecting optical system and an image transfer method using a mask built in an optical system for image transfer, wherein the one of the through-hole and the blind-hole is used as one of a positioning mark and a guide mark, wherein two or more of the one of the through-hole and the blind-hole are each used as a positioning mark or a guide mark, and wherein one of an average position of coordinates and an area center of a gravity position of the two or more through-holes or blind-holes is used for positioning.
