Gartner Says Worldwide Semiconductor Market to Grow 4.6 Percent as Revenue Reaches $314 Billion in 2011

Industry News | 2010-12-10 14:49:08.0

As the semiconductor industry completes one of its most successful years in 2010, the market is positioned for continued, albeit slower, growth in 2011, according to the latest outlook by Gartner, Inc. Worldwide semiconductor revenue is forecast to total $314 billion in 2011, up 4.6 percent from 2010's estimated revenue of $300.3 billion.

Characterization, Prevention and Removal of Particulate Matter on Printed Circuit Boards

Technical Library | 2016-12-22 16:44:04.0

Particulate matter contamination is known to become wet and therefore ionically conductive and corrosive if the humidity in the environment rises above the deliquescence relative humidity (DRH) of the particulate matter. In wet condition, particulate matter can electrically bridge closely spaced features on printed circuit boards (PCBs), leading to their electrical failure. (...) The objective of this paper is to develop and describe a practical, routine means of measuring the DRH of minute quantities of particulate matter (1 mg or less) found on PCBs.

An Automatic Surface Defect Inspection System for Automobiles Using Machine Vision Methods

Technical Library | 2020-08-27 01:15:10.0

Automobile surface defects like scratches or dents occur during the process of manufacturing and cross-border transportation. This will affect consumers' first impression and the service life of the car itself. In most worldwide automobile industries, the inspection process is mainly performed by human vision, which is unstable and insufficient. The combination of artificial intelligence and the automobile industry shows promise nowadays. However, it is a challenge to inspect such defects in a computer system because of imbalanced illumination, specular highlight reflection, various reflection modes and limited defect features. This paper presents the design and implementation of a novel automatic inspection system (AIS) for automobile surface defects which are the located in or close to style lines, edges and handles. The system consists of image acquisition and image processing devices, operating in a closed environment and noncontact way with four LED light sources. Specifically, we use five plane-array Charge Coupled Device (CCD) cameras to collect images of the five sides of the automobile synchronously. Then the AIS extracts candidate defect regions from the vehicle body image by a multi-scale Hessian matrix fusion method. Finally, candidate defect regions are classified into pseudo-defects, dents and scratches by feature extraction (shape, size, statistics and divergence features) and a support vector machine algorithm. Experimental results demonstrate that automatic inspection system can effectively reduce false detection of pseudo-defects produced by image noise and achieve accuracies of 95.6% in dent defects and 97.1% in scratch defects, which is suitable for customs inspection of imported vehicles.
