Abstract

The invention discloses a back drilling method, device and equipment for a printed circuit board, and a storage medium. The method comprises the steps: obtaining a program for carrying out backdrilling operation on a printed circuit board, and taking the program as an original program; selecting a mode of performing backdrilling operation on the printed circuit board; calculating the drilling depth of a drilling tool into the printed circuit board when the backdrilling operation is performed on the printed circuit board in the mode, and taking the drilling depth as a target depth; adjusting the original program according to the target depth to obtain a target program; distributing a drilling tool suitable for executing backdrilling operation to the printed circuit board; and driving a drilling machine on a production line to use the drilling tool to perform backdrilling operation on the printed circuit board according to the target program. According to the method, the program requiredfor manufacturing the printed circuit board is obtained, the mode of executing the backdrilling operation is autonomously selected, the target depth of backdrilling is calculated according to different modes, the backdrilling program is adjusted according to the target depth, the printed circuit board scrap risk caused by manual misoperation is reduced, and the production efficiency is improved.

Description

technical field [0001] The embodiment of the present invention relates to a printed circuit board processing technology, in particular to a method, device, equipment and storage medium for back drilling of a printed circuit board. Background technique [0002] In the PCB (printed circuit board) manufacturing process, the function of the backdrilling process (backdrill) is to remove the copper in the through-hole segment that does not play any connection or transmission role, so as to avoid this part of the metal residue (stub) causing the signal to be in the air. During the transmission process, the signal is finally "distorted" due to reflection, scattering, delay, etc. Therefore, in the process quality control of the back-drilling process, the back-drilling depth control is a key factor affecting signal integrity, and it is necessary to effectively control the back-drilling depth in actual production. [0003] In the traditional back-drilling process, it is necessary to m...
