Flexible circuit board manufacturing process automatic monitoring and intelligent analysis system and method

Abstract

The invention provides a flexible circuit board manufacturing process automatic monitoring and intelligent analysis system and method. The flexible circuit board manufacturing process automatic monitoring and intelligent analysis system includes a basic information module, a parameter acquisition module, a comprehensive database module, an intelligent data analysis module and a monitoring display and data report module; the parameter acquisition module includes a microscope automatic data acquisition device and a copper thickness testing device; the microscope automatic data acquisition device acquires line width and line distance of an etching processing procedure and aperture of a drilling processing procedure, the copper thickness testing device is adopted to measure copper thickness, and to procedure defect data are put into statistics; and a multivariate statistical process control method, a neural network and a support vector machine are adopted as basic analysis methods so as to perform intelligent analysis on acquired data, and predict processing procedures and production line abnormalities, and identify generated abnormality sources. With the flexible circuit board manufacturing process automatic monitoring and intelligent analysis system and method of the invention adopted, automatic monitoring on the manufacturing process and the quality of a flexible circuit board can be realized, and the stability of the procedures and the yield of products can be improved.

Description
