Zusammenfassung: | The invention provides a back drilling detection method and system, and the method comprises the steps: obtaining a back drilling program of a to-be-detected board, and calling the theoretical position information of a to-be-back-drilled hole from the back drilling program; acquiring an image of the to-be-detected plate, and determining processing position information of the to-be-back-drilled hole according to the image of the to-be-detected plate; generating a hole position compensation file based on the theoretical position information and the processing position information; correcting the back drilling program according to the hole site compensation file to obtain a compensation back drilling program; performing back drilling on the to-be-tested board by using the compensation back drilling program; and performing back drilling detection on the to-be-detected plate after the back drilling processing by using the compensation back drilling program. The hole site in the back drilling program is compensated |
