Quality control expert system and method for FPC manufacturing process

Abstract

The invention discloses a quality control expert system and method for an FPC manufacturing process. The system comprises a data collection module, an intelligent analysis module, a warning management module and a database management module. Key physical parameters and FPC defect data of FPC manufacturing procedures are collected through the data collection module; afterwards, the physical conditions of the procedures are evaluated through a neural network; finally, defects generated in the procedures are automatically diagnosed and analyzed through an expert system, and early warning and warning are performed according to the diagnosis results and analysis results of the defects. The expert system diagnoses and analyzes the corresponding defects on the basis of the neural network, so that the bottleneck problem of knowledge acquisition for the expert system and the problems of misdiagnosis and rule conflicts in the diagnosis process are solved. According to the quality control expert system and method, the problems existing in quality control and defect analysis of the key working procedures in the FPC manufacturing process at present can be effectively solved, increase of the automation degree of the whole FPC manufacturing process and improvement on the production efficiency in the whole FPC manufacturing process are facilitated, and production failures are reduced.

Description

technical field [0001] The invention relates to the technical field of quality control in the manufacturing process of a flexible printed circuit board (FPC for short), in particular to an expert system and method for quality control in the FPC manufacturing process. Background technique [0002] As the new darling of the modern electronics industry, flexible circuit boards are developing at an astonishing speed. Finished product testing and other processes. Among them, etching, drilling, copper plating, and finished product inspection are the key processes in the FPC manufacturing process, and the working status of these processes largely determines the quality of the FPC. Through the monitoring of these key processes, measures can be taken in time when the key processes are abnormal, so as to reduce the risk of production line failure and help reduce enterprise costs. Therefore, research on the monitoring of key processes has attracted more and more attention in the indus...
