Abstract: This paper reviews on a Bare Printed Circuit Board inspection system using image analysis wherein the inspection algorithm mainly focuses on the defect detection and classification using the real images. In this project, we have built a MATLAB program to detect Bare PCB faults and classify them and results are properly shown on a GUI using MATLAB. This paper reduces the flaws in defect detection using JIG tool and by human visual inspection. MATLAB image processing software combined with Arduino hardware provides a low cost solution for PCB inspection.

Keywords: PCB, MATLAB, Image Subtraction, Classification.
