Abstract

The invention discloses a back-drilling method, device, equipment and storage medium of a printed circuit board. The method comprises: obtaining a program for performing a back-drilling operation on a printed circuit board as an original program; selecting and executing the printed circuit board The mode of the back drilling operation; calculate the depth of the drill bit into the printed circuit board when performing the back drilling operation on the printed circuit board in the mode, as the target depth; adjust the original program according to the target depth to obtain the target program; for the printed circuit The board distributes drills suitable for performing back-drilling operations; drives the drills on the production line to use the drills to perform back-drilling operations on printed circuit boards according to the target program. Obtain the programs required for making printed circuit boards, independently select the mode of back-drilling operation, calculate the target depth of back-drilling for different modes, adjust the back-drilling program according to the target depth, and reduce the printing caused by manual operation errors The risk of circuit board scrapping 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...
