Electronic components industry has become an important part of the development of electronic information industry. It contains two aspects, one is the electronic component, the other is the device.

Taking discrete devices as an example, they can be divided into diodes, triodes and transistors, etc., and the integrated circuits in devices also include analog circuits, microprocessors and logic integrated circuit memory, etc. As the basic force of electronic information industry, electronic components industry is the focus of development and innovation in the new era.

The development process of China's electronic components is from shallow to deep, from less to more, until the accumulation of a certain degree, to obtain excellent results. In the middle and late 1950s, North China Radio Equipment Joint Factory was the first comprehensive component factory in China.

Until the 1990s, China's communication industry was comprehensively reformed, and the development speed of computer, Internet, automotive electronics and consumer electronics industries was getting faster and faster. At this time, influenced by the transfer of international manufacturing industry to China, China's electronic components industry gained a lot. According to statistics, the total output value of China's electronic components industry accounts for about 20% of the electronic information industry, and the electronic components industry has become the basic content to guide the sustainable development of China's electronic information industry.

The emergence of electronic components industry in the 20th century has brought new changes to the whole world and people's way of work and life. In a certain sense, the development process of electronic components is the development process of electronic industry. In the early 1900s, Lee Dforester proposed the triode as a way to amplify the sound current of the telephone. After this, people are more eager to appear new solid devices, used to replace the traditional sense of amplifier and electronic switch. In the late 1940s, the emergence of point-contact germanium transistors prompted the development of electronic devices to open a new chapter in history. However, in practice, it is found that the proposed point-contact germanium transistor has the problem of unsteady contact point in its composition.
