Neural Network Diagnosis for Visual Inspection in Printed Circuit Boards
In this paper we present an Automatic Optical Inspection system to diagnose Printed Circuit Boards mounted in Surface Mounting Technology. The diagnosis task is handled as a classification problem with a neural network approach. The Printed Circuit Board tested images are preprocessed by means of several methods to reduce the amount of data to feed to the neural networks. We compare the results...
متن کاملCrosstalk on Printed Circuit Boards
This document treats the crosstalk between parallel conductors. The conductors can represent either conductors in a multiconductor cable or traces on a printed circuit board (PCB). An analysis method based on a lumped circuit equivalent for the problem as well as a method to calculate the per unit length parameters are presented. The computed results are validated by comparison with measurement...
متن کاملA Neural Network Approach to the Inspection of Ball Grid Array Solder Joints on Printed Circuit Boards
In this paper; we described an approach to automation of visual inspection of BGA solder joint defects of surface mounted components on printed circuit board by using neural network. Inherently, the BGA solder joints are located below its own package body, and this induces a diflculty of taking good image of the solder joints by using conventional imaging system. To acquire the cross-sectional ...
متن کاملArtificial neural network approach for functional fault diagnosis of complex Printed Circuit Boards
With the continuous increase in the complexity of electronic systems the issue of testing such systems is becoming an increasingly difficult task. The large number of constituent components on a printed circuit board and their internal complexity rules out traditional simulation-based techniques and emphasis upon using techniques which are based on artificial intelligence. This work is a contin...
متن کاملFoldable Printed Circuit Boards on Paper Substrates
This paper describes several low-cost methods for fabricating flexible electronic circuits on paper. The circuits comprise i) metallic wires (e.g., tin or zinc) that are deposited on the substrate by evaporation, sputtering, or airbrushing, and ii) discrete surface-mountable electronic components that are fastened with conductive adhesive directly to the wires. These electronic circuits—like co...
