Third, the welding technology

Students need to learn and master welding technology, including the correct use of welding table, solder, welding wire and other tools and materials. Task requirements may include the ability to make welding connections, repair welding errors and check welding quality.

Fourth, welding practice

Students need to practice welding and make welding connection according to the given task requirements. Task requirements may include soldering electronic components to printed circuit boards (PCB), making simple electronic circuits, etc.

Verb (short for verb) resolves disputes.

Students need to learn and master the basic methods and skills of troubleshooting. Task requirements may include determining and repairing faults in electronic circuits by checking solder connections, measuring circuit parameters, etc.

Brief introduction and development history of electronic components

I. Introduction of Electronic Components

Electronic components are electronic components and parts of small machines and instruments, which are often composed of several parts and can be used in similar products. It often refers to some parts of electrical appliances, radios, meters and other industries, and is the general term for capacitors, transistors, hairsprings, clockwork and other electronic devices. Common ones are diodes and so on.

Electronic components include: resistors, capacitors, inductors, potentiometers, electron tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, electroacoustic devices, laser devices, electronic display devices, photoelectric devices, sensors, power supplies, switches, microprocessors, etc.

Second, the history of development

Due to the needs of social development, electronic equipment has become more and more complex, which requires electronic equipment to have the characteristics of reliability, high speed, low power consumption, light weight, miniaturization and low cost.

Since the idea of integrated circuits was put forward in 1950s, the first generation of integrated circuits was successfully developed in 1960s due to the progress of material technology, device technology and circuit design.
