Method for automatic check of process data of printed circuit board

The invention discloses a method for automatic check of process data of a printed circuit board (PCB), comprising formulating a manufacturability check rule according to a PCB manufacturability design specification; establishing a check rule database including the manufacturability check rule and PCB manufacturer processing information; reading PCB process data from light-plotting and drilling files introduced from an EDA; designing a universal data structure to integrate the process data; hierarchically and visually displaying a PCB light-plotting effect drawing; and calling the check rule during the check process to perform manufacturability check on the process data, performing a qualification check to the PCB manufacturer processing, and classifying and outputting the check result list. The method causes a user to be independent from an EDA (electronic design automation) design environment; the method is suitable for PCB manufacturers, professional EDA/CAD (computer aided design) companies and independent
