![]() In order to minimize scrap caused by the wrongly etched PCB panel, inspection has to be done in early stage. The main objective of Etching process is to remove the exposed unwanted copper other than the required circuit pattern. Printed circuit board ( PCB) fabrication is a multidisciplinary process, and etching is the most critical part in the PCB manufacturing process. are to be considered to ensure good quality of the image which can then be used for defect detection. Many practical issues like tilt of the images, bad light conditions, height at which images are taken etc. In this PCB inspection system the inspection algorithm mainly focuses on the defect detection using the natural images. To meet such expectations, identifying various defects and their types becomes the first step. The importance of the Printed Circuit Board inspection process has been magnified by requirements of the modern manufacturing environment where delivery of 100% defect free PCBs is the expectation.
