A method for generating high-precision drilling files for PCB boards and a drilling method

Abstract

The invention discloses a method for generating a high-precision drilling file of a PCB board, which comprises the following steps in sequence: obtaining data information; obtaining coordinates Xmin, Xmax, Ymin and Ymax based on the actual size of the PCB board; synchronizing an Oracle database, obtaining an information list and looping the list information one by one, and then judging whether it is segmentation information, if so, proceeding to the next step, otherwise directly outputting the data, the segmentation information refers to a PCB board whose segmentation mode has been determined, the segmentation mode includes 2-segmentation and 4-segmentation, determining the segmentation mode and the segmentation point; determining the segmentation area according to Xmin, Xmax, Ymin, Ymax and the segmentation point; the drilling compensation values ​​of the same segmentation area on the PCB board are the same, the data information in the data is screened, arranged in the order of the segmentation area, the data is sorted, and the drilling file is generated. The method of the invention is conducive to improving the accuracy of drilling holes in the PCB board, each area is compensated according to the same expansion and contraction coefficient, the process is not cumbersome, the drilling effect is good, the quality of the PCB board is ensured, and the efficiency is high.
