The automatic checkup method for PCB processing data based on knowledge

The PCB production and quality are directly affected by processing data in the design and manufacture file. At present, the existing checkup tools for processing data have some shortages, such as too few objects examined, inconvenience, poor flexibility and scalability, and so on. An automatic checkup method based on knowledge for PCB processing data is presented in this paper, which automatically checks the processing data by the rules, predicate logic operating, deductive reasoning, and the given reasoning model. Experimental results show that this method works well and has strong flexibility, adaptability and scalability.
