Materials for Electrical and Electronic Contacts: Processing, Properties, and ApplicationsThe subject of electrical contact materials is of interdisciplinary nature, demanding knowledge of pure sciences such as physics and chemistry, and applied sciences like electrical and electronics engineering, metallurgical engineering and materials science, polymer science and engineering, ceramic science and engineering, over and above the knowledge of environmental aspects particularly when dealing with disposal of products. The aim of this book is to provide state of the art information on materials, and processing and applications of electrical and electronic contacts. The book will introduce the academic community to the subject of electrical and electronic materials. For the industrial users, it is a comprehensive source of information on manufacturing, evaluation and applications of electrical and electronic contact materials. The book would be of immense utility to scientists, engineers and technocrats engaged in the field of switchgear technology, integrated circuits and microelectronics. |
