Method and system for automatically auditing PCB project files

Abstract

The invention relates to a method and a system for automatically auditing PCB project files. The method comprises the following steps of receiving a file packet submitted by a user, wherein the file packet comprises a Gerber file and / or a plate-making instruction file; on-line displaying the graph of the Gerber file, and using a preset parameter extraction rule to analyze the Gerber file and / or using a general engineering parameter description language rule base to analyze the plate-making instruction file, and acquiring a PCB project parameter; generating an SPEC file according to the PCB project parameter, integrating the analytical results, then outputting and displaying. The method for automatically auditing the PCB project files provided by the invention recognizes the PCB project parameter by comparing with the received Gerber file according to the preset rule, so that the system can automatically recognize the PCB project parameter and standardize the PCB project parameter and then output the PCB project parameter to the user, therefore the manual audit time of the Gerber file is shortened, the efficiency of PCB material collecting and auditing is improved, and the audit process and the audit result are more intuitive.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a method and system for automatically checking PCB engineering documents. Background technique [0002] At present, a PCB (Printed Circuit Board, printed circuit board) project file is usually composed of multiple Gerber files and / or plate-making description files. Traditionally, the review process for PCB project files requires engineering personnel to interpret, and each Gerber corresponds to a layer. Manually judge the format, inter-layer alignment, layer judgment, measure size, establish Profile, judge the total number of holes, the minimum hole diameter, etc., because the graphic elements may exceed 1 million, it takes a long time to check and analyze the rules involved to calculate a large number of the most In case of violation of line width and line spacing, it takes a lot of time for engineers to eliminate false lines, copper skins and characters.
