The invention discloses a method and a device for acquiring a back drilling hole detection file of a PCB (Printed Circuit Board) and optical detection equipment. The method comprises the following steps of acquiring a back drilling hole file and a through hole file; obtaining a rigid body transformation matrix between the back drilling hole file and the through hole file; performing rigid body transformation on each back drilling hole in the back drilling hole file according to the rigid body transformation matrix so as to obtain a through hole corresponding to each back drilling hole from the through hole file; and obtaining a back drilling hole detection file according to the through hole corresponding to each back drilling hole and the back drilling hole file. Therefore, the back drilling hole information can be obtained by analyzing the through hole file and the back drilling hole file, and the obtaining speed and accuracy of the back drilling hole detection file are effectively improved.
Description
technical field [0001] The invention relates to the technical field of PCB board detection, in particular to a method, device and optical detection equipment for acquiring a PCB board back drilling detection file. Background technique [0002] At present, the AOI (Automated Optical Inspection) used for PCB back-drilling inspection uses the analysis of ODB++ files or Gerber files to extract the back-drilling inspection data. Among them, the ODB++ file integrates all PCB and Functional description of circuit board assembly; Gerber files are a collection of document formats for circuit board industry software to describe circuit board (circuit layer, solder mask layer, character layer, etc.) images and drilling and milling data, and are the standard format for image conversion in the circuit board industry . [0003] However, when extracting the back drilling detection data by parsing the ODB++ file or the Gerber file, since the ODB++ file or the Gerber file contains a large a...
