Method for checking electric fitting data of printed circuit board

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 t
