The importance of electronic components

The electronic components industry has now become an important part of the development of the electronic information industry. It contains two aspects, one is electronic components, the other is devices. Take the discrete device in the device as an example, it can be divided into diodes, transistors and transistors, and the integrated circuits in the device also include analog circuits, microprocessors and logic integrated circuit memories. As the basic force of the electronic information industry, the electronic component 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, and it is not until they have accumulated a certain degree that they have achieved excellent results. In the middle and late 1950s, North China Radio Equipment Joint Factory was the first comprehensive component factory in my country in the true sense. Until the 1990s, China's communications industry has been completely reformed, and the development of industries such as computers, the Internet, automotive electronics, and consumer electronics is becoming faster and faster. , Promote a lot of gains in China's electronic components industry. According to statistics, the current total output value of my country's electronic component industry accounts for about 20% of the electronic information industry, and the electronic component industry has also become the basic content that guides the sustainable development of my country's electronic information industry.

The electronic component industry that emerged in the twentieth century has brought new changes to the world and people's work and lifestyle. In a certain sense, the development process of electronic components is the development process of the electronics industry. At the beginning of the twentieth century, Lee DeForest proposed a vacuum triode, which was used to amplify the sound current of telephones. After this, people are eager to appear new solid-state devices to replace traditional amplifiers and electronic switches. In the late 1940s, the emergence of point-contact germanium transistors prompted a new chapter in the development history of electronic devices. However, in practical application, it was found that the newly proposed point-contact germanium transistor has the problem of unstable contact point in the composition.
