The state of the art in printed wiring board inspection
Automated visual inspection of printed wiring is providing research opportunities in completely utomated optical systems technology. This paper addresses device design considerations, articularly the important problem of turning an optical inspection device into a tool for lanufacturing process analysis and control.
متن کاملWavelet - Based Printed Circuit Board Inspection System
An automated visual printed circuit board (PCB) inspection system proposed in this paper is designed specifically to detect various types of defects occurred during circuit printing process in manufactory. Two-dimensional HAAR wavelet transform is incorporated in the PCB inspection algorithm of the inspection system. During the inspection, two type of images are required; reference and tested P...
متن کاملPrinted circuit board inspection
This paper provides a general overview of immediate and long-term aims of the printed circuit board inspection project of The Robotics Institute. Its purpose is to highlight some of the significant issues specific to printed circuit board inspection and to provide a discussion of our basic thesis that machine inspection should be coupled with machine diagnosis of the causes of observed printed ...
متن کاملComputer Vision System for Printed Circuit Board Inspection
In this paper we present a Computer Vision system for printed circuit board (PCB) automated inspection. In the last years PCB industry has been invested in manufacturing automation improvement. This is known, especially in measurement and inspection field. We can note that the tolerances on PCB assembly become more accurate. With computer hardware and cameras advances, new Computer Vision algor...
متن کاملOptical interconnect on printed wiring board
Integration of high-speed parallel optical interconnects into printed wiring boards (PWB) is studied. The aim is a hybrid optical–electrical board including both electrical wiring and embedded polymer waveguides. Robust optical coupling between the waveguide and the emitter/detector should be achieved by the use of automated pick-and-place assembly. Different coupling schemes were analyzed by c...
