Detection and classification of defects on surface mount device printed circuit board (SMD-
PCB) is an important requirement in electronic manufacturing process. This process which is …

This project is motivated mainly by the need for more efficient techniques in inspection of the
PCB in fabrication process. The objectives of this project are to provide an inexpensive and …

In this paper, based on the images acquired from a 3-CCD color camera and a 3-color
hemispherical circular illumination, a high speed algorithm is given to inspect the chip …

This paper presents the implementation of a number of elitist schemes for a low cost printed
circuit board (PCB) inspection system. This strategy also aims to explore the role of …

With the large variations in appearance for different kinds of defects in Printed Circuit Boards
(PCBs), conventional rule-based inspection algorithms become insufficient for detecting and …

The paper presents a novel integrated system in which a number of image processing
algorithm are embedded within a genetic algorithm (GA) based framework in order to …

This paper investigates the possibility of enhancing a flying probe tester (FPT) with an
automated optical inspection (AOI) module. The goal is to achieve a wider range of defect …

Automated systems based on optical inspection are widely used in the production of
electronic systems, mainly on the printed circuit board level. Detection of defects in the early …

Automated visual inspection algorithms for printed circuit boards have long been focused on
geometric defects of conductive paths that comprise regularly straight line and circular arc …

A technique of PCB layout optical inspection based on image comparison and mathematical
