Abstract

Achieving 100% defect-free Printed Circuit Boards (PCBs) is imperative in modern manufacturing. The demand for PCB inspection has surged, prompting advancements in CNC machine technology. This project focuses on comparing PCBs fabricated by a 3-axis CNC machine, employing image processing techniques, including Homography transformation, to detect defects. Misalignment poses a significant challenge during comparison. Utilizing a TB-6560 controller, PCBs are automatically fabricated, and images are captured for analysis in MATLAB. Various image processing algorithms, along with Homography transformation, are applied to detect defects and address misalignment issues. The study also evaluates the precision of the CNC machine.
