The systems of non-destructive control have been widely practiced in science and industry. This paper focuses on the development of the technique of detection and localization of differences on the images of printed circuit boards, which is achieved by comparing of the images with the reference ones.

The increase in the use of electronic products has increased production printed circuit boards, boards etching, micro-etching process, will produce a large number high concentration copper-containing etching waste liquid, these if directly discharged, not only cause serious pollution to human living environment, but also copper resources be wasted. Therefore, this paper adopts closed circulatio...

In the present work, a new sensor for morphine (MO) measurement, based on modification of screen-printed carbon electrode (SPE) by using magnetic core shell manganese ferrite nanoparticles was reported. The electrochemical behaviour of MO was investigated in phosphate buffer solution (pH 7.0) by voltammetry. The electrochemical response of the modified electrode toward morphine was studied by m...

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 ...

Zusammenfassung Neue Entwicklungen in der Elektronik wie massengedruckte Einfachelektronik ermöglichen den Einsatz von Computersystemen an oder gar in Objekten, für die bisher ein solcher Einsatz nicht wirtschaftlich sinnvoll war. Dieser Beitrag untersucht die prinzipiellen Rahmenbedingungen bei der nahtlosen Integration von Smart Objects in bestehende IT-Strukturen. Probleme bei der Einbindung...

An innovative technology for the mass production of stretchable printed circuit boards (SCBs) will be presented in this paper. This technology makes it possible for the first time to really integrate fine pitch, high performance electronic circuits easily into textiles and so may be the building block for a totally new generation of wearable electronic systems. An overview of the technology wil...

INTRODUCTION During the library loan process, the printed resources can be a carrier of pathogenic bacteria. In this study, it was tried to compare the Bacterial Contamination Rates and their antibiotic sensitivity pattern in printed resources of a hospital and a non-hospital library. METHODS This is a cross-sectional study. Returning books from the Al-Zahra hospital library and library of Sc...
