Electrician refers to the personnel engaged in power production and electrical manufacturing, electrical maintenance, construction and installation and other industrial production systems. Summary III of XX electrician training Report, I hope it will help you! Training purpose: The main purpose of electronic technology practice is to cultivate our hands-on ability, so that we can identify common electronic components, operate corresponding electrical tools, use related instruments, understand the whole process of electronic equipment manufacturing, assembly and debugging, and master the common methods of finding and troubleshooting electronic circuits. Make us have a certain perceptual and rational understanding of the installation and debugging of electronic components and radios, master the actual production knowledge and assembly skills of radios, and cultivate the ability to integrate theory with practice! The specific points are as follows: 1) Master the correct use of electric soldering iron and be familiar with the use and maintenance of manual welding tools. 2) Basically master the welding technology of manual soldering iron, and be able to independently complete the installation and welding of simple electronic products. Familiar with the production process of electronic product installation process. 3) Be familiar with the categories, models, specifications, performance and application scope of commonly used electronic devices, and be able to consult relevant electronic device books. 4) Be able to correctly identify and select common electronic devices, and skillfully use common multimeter and digital multimeter.

5)? Learn to read the circuit diagram, be familiar with the identification of symbols of electronic components, and master electricity? Sub-product welding and circuit debugging. ? 6)? Understand the structure and working principle of some common electronic products. ? Second,? Internship content? 1)? Understand the common sense of standardized operation and safe use of electricity, and learn to recognize simple electronics? Ok, learn the correct welding method and know the composition of the radio. ? 2)? Understand the types and working principles of radios and design electronic devices? Work flow, understand the types, models, scope of use and methods of radio components? Methods, master how to choose electrical components correctly. ? 3)? Learn the operation methods and precautions of welding, practice and master welding? Connection technology. ? 4)? Distribute and inventory electronic equipment and learn to use tools to test electronic equipment. Check whether the equipment works normally. ? 5)? Learn to read the circuit diagram, complete the soldering of the circuit board and debug the radio. A lot of work. ? Third,? Internship equipment:? 1)? Electric soldering iron: Because there are many components to be soldered, external thermoelectric is used? The power of soldering iron is 30w, and welding head is made of copper. ? 2)? Screwdriver, tweezers and other necessary tools. ? 3)? Rosin and tin can be welded quickly because of their low melting points? Scattered on the metal surface, the welding is firm and the solder joint is bright and beautiful. ? 4) Two No.5 batteries. ?

Fourth, the internship principle? Electrical components? Resist? 1)? Resistance is divided into fixed resistance and variable resistance. ; From materials? Is it divided into carbon film, metal film and metal oxide film? ; From the production, it is divided into winding and pottery making. Porcelain, cement, film, thick film, glass glaze, etc. ? 2)? The nominal resistance value of resistor is generally expressed by color ring method. Among them? 4? The error of 4-ring resistor is larger than that of commonly used 5-ring resistor. In electronic products, what else? 5 ring resistance is generally metal oxide film resistance, mainly? Used for precision equipment or instruments. ? Capacitance? According to the structure, it can be divided into fixed capacitance, variable capacitance and fine tuning capacitance.
