An AI-based manufacturing design rule checker and path optimizer for PCB production preparation and manufacturing

Abstract

The authors discuss printed circuit board (PCB) manufacturing design rule checking (MDRC) in combination with the path optimizing of the assembly process in a heterogeneous, distributed, and networked information system environment linked with databases in a defined factory infrastructure. An increase in the degree of automation requires greater continuity of information flow starting with the customer order through to the sensor and actuator layer of manufacturing machinery. After the presentation of information infrastructure models such as the hierarchical production control system and the Y-model, the manufacturing design system (MDS) for the production preparation environment is derived which contains also the manufacturing design rule checking and path optimizing applicable to the PCB assembly process. In particular, the linkage between the design rule checking and the path optimizing process via the hierarchical two-phase cross-linked unit formation method based on technical and strategic characteristics is considered. The assembly process of a PCB with different components is cited as an example. The software package is written in the artificial-language Common LISP with the dialect SCHEME.<>
