Preface
The book is primarily aimed to serve the acute demand of the students of ECE, EE, EIC
Electrical engineering and diploma, searching useful matter on ‘electronic materials, compo-
nents and process’.
The book covers each and every topic as per the syllabus of university of Rajasthan, of the
third semester B.E./B.Tech courses, but this can also be used profitably by engineering under-
graduates of other Indian Technical Universities.
The book is organized into 10 chapters. Chapter 1 is an additional introduction chapter,
which discusses the basic fundamental concepts of material science. Chapters 2 to 7 provide
characteristic properties exhibited by various electronic materials in response to external
factors like temperature, pressure, stress, electric field, magnetic field etc.
Increasing importance of material science has led to a number of new devices used in
present day electronic engineering. Chapter 8 deals with discrete passive component types
and their fabrication methods. Chapters 9 and 10 provide knowledge on printed circuit boards
and surface mount technology.
At the end of each chapter, the text is followed by a number of theory questions and solved
problems picked from past examination question papers. A list of units and constants, prefixes,
values of multiples and submultiples and greek alphabets have been included at the beginning
of this book.
Throughout the book, stress has been given on fundamental concepts through illustrative
examination. It is kept in consideration to use easy language, keeping in view the different
language background of students. This concise and comprehensive text will present the stu-
dents with a single book containing all essential theories on the subject.
This book would have not been possible without the enormous encouragement, guidance
and good wishes of Prof. M.L. Sisodia.
I deeply acknowledge my parents and other family members for their never-ending encour-
agement, moral support and patience during the preparation of this book.
I also thank New Age International, the publisher of this book, for their keen interest and
kind cooperation in bringing the book well in time.
Last, but not the least, I also thank my friends and colleagues for their valuable suggestions
and help in preparing this book.
