pcb defect detection matlab code

This project presents a new implementation which separates two of the existing groups containing two defects each into four new groups containing one defect each by processing synthetic images of bare through-hole single layer PCBs using MATLAB Image Processing. This also will use Mathematical Morphological Toolbox here. Morphological process involves techniques such as dilation, erosion, opening and closing which helps in partitioning the images and associates certain types of defects with certain patterns. Th ....etc

INTRODUCTION
Lithography was the first fundamentally new printing technology since the invention of relief printing in the fifteenth century. It is a mechanical Plano graphic process in which the printing and non-printing areas of the plate are all at the same level, as opposed to intaglio and relief processes in which the design is cut into the printing block. Lithography is based on the chemical repellence of oil and water. Designs are drawn or painted with greasy ink or crayons on specially prepared limestone. The stone is moistene ....etc

Abstract

The importance of the Printed Circuit Board inspection process has been magnified by requirements of the modern manufacturing environment. In electronics mass production manufacturing facilities, an attempt is often to achieve 100% quality assurance. In this work Machine Vision PCB Inspection System is applied at the first step of manufacturing. In this system a PCB inspection system is proposed and the inspection algorithm mainly focuses on the defect detection and defect classification of the defects. Defect classification is esse ....etc

pcb layout guidelines

1. for prototype Whenever possible avoid using bread-board or vari-board with RF modules The long tracks inside these types of prototyping board introduce large capacitances /inductances to the circuit which can badly distort / detune rf signals. Ideally prototype or evaluation pcbs should be used.

2. Tracks connected to the antenna (RF input / output) pin of transmitter and receiver modules should be as short as possible. Any conductor connected to this track will act as an antenna, so it will lengthen and detune t ....etc

Software Defect Association Mining and Defect Correction Effort Prediction (Java, VB.NET)
IEE Transactions on Software Engineering, Vol. 32, No. 2,

Abstract: Much current software defect prediction work focuses on the number of defects remaining in a software system. In this paper, we present association rule mining based methods to predict defect associations and defect correction effort. This is to help developers detect software defects and assist project managers in allocating testing resources more effectively. We applied the proposed ....etc
