System and Method for Classification of PCB fault and Type of Fault

摘要

The present invention discloses a system and method for classifying PCB defects and defect classes. A PCB defect classification system according to an embodiment of the present invention performs a difference operation between a standard image corresponding to a PCB (Printed Circuit Board) design file and an inspection object image which is an image of a PCB to be inspected, and detects all defective areas in the inspection object PCB Detector; And a classifier for classifying defect types of each defective area including a simple defect and a complex defect by using at least one of a defect type, an edge type change frequency, and a background ratio of each detected defect area .;
