Method for checking electric fitting data of printed circuit board

Abstract

The invention discloses a method for checking electric fitting data of a printed circuit board, which mainly solves the problem that the electric fitting data of the printed circuit board cannot be automatically checked in the prior art. The method comprises the following steps of: converting automatic design files of electronic design of different structures into normalized files; digitalizing the assembled design specifications of the printed circuit board into process rules for checking, establishing a surface mounting process rule database and storing the process rules; recovering geometric shapes of a substrate and components of the printed circuit board by using visualization technology, and three-dimensionally and dynamically displaying the mounting process of the printed circuit board; checking the assembly properties of the components to be mounted by using the surface mounting process rule database as a drive, and recording the checking results; and classifying the checking results, and outputting the checking results in a figure or graph mode. By the method, the data for the automatic design files of the electronic design of different structures can be automatically checked, and the checking results can be intuitively displayed; moreover, the method can be used for surface mounting production preparation of the electric fitting industry.

Description

technical field [0001] The invention belongs to the technical field of computers, relates to a method for reviewing electrical equipment data of printed circuit boards, and can be used for pre-production preparation of surface mounting in the electrical equipment industry. Background technique [0002] In electronic design and manufacturing, the printed circuit board (PCB), as a subsystem of electronic products, plays the role of the core module unit. However, there are many types of electronic design automation EDA design software on the market at present, and the PCB design results are generally saved in the format of each EDA software company, and there is no unified data storage format. Although some EDA design software adopts the method of mutually supporting data formats, it cannot directly extract the information for assembly, which brings many difficulties to the assemblability review of various electronic design files.

Problems solved by technology

However, there are many types of electronic design automation EDA design software on the market at present, and the PCB design results are generally saved in the format of each EDA software company, and there is no unified data storage format.

Although some EDA design software adopts the method of mutually supporting data formats, it cannot directly extract the information for assembly, which brings many difficulties to the assemblability review of various electronic design files

[0003] EDA design software generally has the function of error detection according to certain design rules, but there is no rule error detection function for electrical equipment design, so assemblability review cannot be performed

Since there is no assemblability review function, it is even more impossible for users to customize the review rules, so that the design experience or rules accumulated by the design team for a long time cannot be well inherited in the design tool
