เนื้อหาย่อ : Electronics assumes an ever greater role in American daily life. Applications seem un- limited; new equipment is being designed all the time; more and more people seek em- ployment, security, and opportunities for advancement in the electronics industry. However, they cannot merely go to work and pick up a knowledge of the trade on the job; they must be trained. A knowledge of basic electronics theory and hardware is necessary in all but the most routine type of assembly work. This text provides a working knowl- edge of theory and practice for those seeking entry into the dynamic and challenging electronics industry. Essentially, the electronics assembler is part of a technical team composed of engi- neers and technicians. The engineer origi- nates fundamental ideas of product and proceeds to plan and design construction. The electronics assembler manufactures the product, following specifications set forth by the engineer. The technician checks out the finished product to see that it meets specifica- tions and functions properly. He is further responsible for maintenance and repair, sO that the equipment stays in operation. In short, the engineer designs the product, the assembler builds the product, and the tech- nician checks the product and maintains it in proper operating condition. The material in this book will be of most interest to those who wish to become elec- tronics assemblers. But anyone interested in the hardware aspects of electronics can bene- fit by studying these fundamentals. The book requires no technical background. It will help the technician lay the groundwork for more theoretical aspects of electronics; it will help sales and administrative personnel be- come better acquainted with the technical aspects of electronics; and it will help the consumer to understand more about the elec- tronics product he buys. Over a period of several years, the authors have developed and used this material to train electronics assemblers and technicians at Compton College. Many students, with
