Electronic technology and radio maintenance technology are by no means easy to learn and can be mastered in a short time. Because this science involves many aspects and all aspects are interrelated, we can only understand and master it as a whole. It is naive to master this technology after learning for three to five months.
This science includes at least three aspects: the working principle of circuits, which is one of them; Fault analysis theory and inspection method, this is the second; Hands-on operation ability is the third. These three skills are indispensable and influence each other.
In terms of learning methods, reading a book once can't solve the problem, and reading a book alone is not enough. When reading a book, read it through once or twice before reciting it when you can understand it. If you don't understand, just put it aside for a while and continue to look down. Don't read it intensively the first time, just want to understand all the problems in the book. This is impossible and unscientific for beginners. Read it through several times, have a certain overall understanding of the working principle of the circuit, and then read the whole book intensively. In learning, we should take a book as the main teaching material, supplemented by many books of the same type as reference books. When there are some incomprehensible parts in the main textbook, refer to the relevant parts of other books.
In the relationship between theory and practice, theory cannot be divorced from practice, and practice should be guided by theory. Reading, doing things and staggering are all good ways. Problems encountered in practice, consult books. This method of reading with questions is much better than simply reading. The perceptual knowledge learned in practice can deepen the knowledge and understanding of theoretical knowledge.
In terms of hands-on operation, we should start with simplicity. For example, you should be familiar with the appearance characteristics of some common components and learn to test their quality with a multimeter. Don't fix the electric appliance in the first place.
After you know something about this science, you should concentrate your energy and time on solving small problems, so as not to blossom in an all-round way. For example, first analyze the working principle of the power supply circuit, then try to install a small regulated power supply yourself, and then study and repair the power supply circuit in a relatively concentrated time, so that you will have a deeper understanding of the power supply circuit.
Where should I start studying?
The scope of learning is very wide, but learning should start with components.
Components are the smallest unit of electronic circuit, the basis of analyzing the working principle of the circuit, and the object of final detection and replacement in maintenance. From understanding and mastering the appearance characteristics, structure, working principle, main characteristics and detection methods of components, we will enter the study of circuit working principle. Of course, it is not required to know all the components, mainly the most basic components such as resistors and capacitors.
How to choose an introductory textbook?
What types of radio books are there?
There are six main types of home radio books: one is the basic circuit working principle books, which can be used as introductory reading materials for theoretical knowledge; Second, books on common sense and detection methods of components can be used as introductory reading materials for hands-on learning; Third, all kinds of books on the working principle of the overall circuit of electronic appliances; Fourth, repair technical books, with examples of fault analysis and repair; Fifth, repair information books; The sixth is to use and maintain books.
What kind of textbooks are better for beginners to choose?
When you are a beginner, you should choose introductory textbooks, such as the basic knowledge of components and transistor circuits. Don't choose textbooks of electronic technology and electronic circuits in middle schools and universities, otherwise you will lose confidence in continuing your study.
Choose books or magazines as the main teaching materials for beginners.
Beginners should choose books as the main teaching materials, because the book content system is not limited by the number of words, with detailed explanations and illustrations, which is suitable for beginners to learn. Of course, some beginner's garden columns in magazines can also be used as reference books.
