PCB Faults Detection Using Image Processing

This paper reviews the digital image processing for PCB fault detection by using MATLAB software. In this project we are implementing different algorithms in sequentional manner with GUI. In this process we are giving two input images one to be inspected for errors i.e. layout of circuit which is implemented on PCB and other one is reference image or standard image of PCB. After these process we can obtained numbers of faults in any respect like hole, Breakout etc. it helps to detect the fault at primary stage of designing. Hence to improve the image quality of compared image we use sharpened process, so we get sharpen images and fault can be detected easily and it is fast and accurate .it reduce the manufacturing cost of PCB
