Introduction to Electronic Maintenance and Repairs.

Abstract

Technology has propelled modern world into an outstanding status not just in product development but also in automation. The extent to which the world has automated her systems is dazzling and it does not seem to have gotten to her wit’s end in this development. Technology which is the driving force behind the world’s outstanding developments draws heavily from electronic principles and applications. Practical application of principles in many engagements places a demand for cognitive and psychomotor skills of manpower in the blue collar job sector which is so critical for development and self-reliance of individuals and nations. Blue collar jobs are major essentials for industrial development and sustainable healthy economic growth of any nation or society. Blue collar jobs are essentially skilled jobs, and equipping for such jobs in a structured educational system calls for ‘mind-on hands-on’ experiences. This, the authors have taken into consideration in authoring the Book, Introduction to Electronic Maintenance and Repairs. The Book is carefully authored to provide the cognitive and psychomotor knowledge and skills that can easily engross learners into sustained study of the subject matter of electronic maintenance and repairs. The authors have included electronic principles and applications to contemporary devices, such as were not captured in older Textbooks in the subject area. The authors, in this five-chapter Book, judiciously delivered concepts and detailed practical steps and approaches that should lead to acquisition of appropriate knowledge and functional skills in principles, tools, equipment, materials, troubleshooting, operation and practices in electronic maintenance and repairs. The blend of rich practical experiences and high academic backgrounds of the three authors coupled with broad content areas that are relevant across the three tiers of Nigerian education make the Book of high and relevant quality. The Book contains enough to empower one to be self-reliant. It is therefore an unemployment tackling textbook for anyone who will want to build skill in electronic maintenance and repairs for either self-employment or paid employment. The hue and cry about non employability of programme graduates from educational and training institutions should be a non-issue in electronic maintenance and repairs for those who will use this Textbook in their training. The exercises at the end of each chapter of the Book provide immediate check of materials learnt at each stage. The Book, Introduction to Electronic Maintenance and Repairs portrays an intensive and comprehensive research into the subject matter lazed with great wealth of experiences. I therefore, strongly recommended it as a good resource text for all that are or will be engaged in maintenance and repairs of electronic devices.
