Terminal blocks are electronic components. I believe that many workers in the electrical industry often say that electronic components, but can not clearly point out which are not part of the scope of electronic components, to sort out today.

 

       Electronic components and components is the general term.

 

       Electronic components: refers to the factory production and processing does not change the molecular composition of the finished product. Such as resistors, capacitors, inductors. Because it does not produce electrons, its voltage, current control and conversion, so called passive devices.

 

       Electronic device: refers to the production and processing in the factory to change the molecular structure of the finished product. Such as a transistor, an electron tube, an integrated circuit, a connector, and a connection terminal. Because it can produce electrons, the voltage, current control, transformations (amplification, switching, rectification, detection, oscillation and modulation, etc.), it is also known as active devices.

 

       Electronic components and electronic components and small electrical machinery, instrument components, which itself often consists of several parts, can be common in similar products; often refers to the electrical, radio, instrumentation and other industrial parts, such as capacitors, transistors , Gossamer, winding and other sub-devices in general. Electronic components include: resistors, capacitors, potentiometers, tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro motor , Electronic transformer, relay, printed circuit board, integrated circuit, all kinds of circuit, piezoelectric, crystal, quartz, ceramic magnetic material, printed circuit substrate substrate, electronic function craft special material, electronic glue (belt) Chemical materials and parts. The terminal block is a connector, and then belong to the scope of electronic components.

 

       Development of electronic components

 

       The development history of electronic components is actually a condensed history of electronic development. Electronic technology is the late 19th century, beginning of the twentieth century began to develop new technologies, the twentieth century, the most rapid development, the most widely used, as modern science and technology development is an important symbol.

 

       The first generation of electronic products to the core of the tube. At the end of the 1940s, the first semiconductor transistor was born in the world. It is small, light, energy saving, long life, etc., and soon to be countries to use, in a large range to replace the tube. The end of the fifties, the world's first integrated circuit, which put a lot of transistors and other electronic components integrated in a silicon chip, so that electronic products to a more compact development. ICs from small-scale integrated circuits to the rapid development of large-scale integrated circuits and VLSI, so that the electronic products toward high-performance low-consumption, high precision, high stability, intelligent direction. As the four stages of the development of electronic computer can just fully explain the four stages of the development of electronic technology, so the following four from the development of electronic computer to illustrate the four stages of development of electronic technology features.

 

       Emergence in the 20th century and the rapid development of electronic components industry so that the whole world and people's work and living habits have undergone enormous changes. The development history of electronic components is actually the development history of electronics industry.

 

       In 1906, Lee de Forrester invented the vacuum transistor, used to amplify the voice of the phone current. Since then, there has been a strong expectation that a solid device can be developed as a light weight, low cost and long life amplifier and electronic switch. In 1947, the birth of point-contact germanium transistors, in the history of the development of electronic devices opened a new page. However, such a point-contact transistor has a fatal weakness in the contact point instability. Junction-type transistor theory has been proposed for the successful development of point-contact transistors, but junction transistor materials have emerged until one can produce ultra-high purity single crystals and can arbitrarily control the conductivity type of the crystal. In 1950, with the use of the earliest germanium alloy type transistor was born. In 1954, the junction type silicon transistor was born. Since then, the idea of a field-effect transistor has been proposed. With the development of non-defective crystallization and defect control technology, extracrystal growth techniques and diffusion doping techniques, fabrication techniques of pressure-resistant oxide films, the emergence and development of corrosion and photolithography techniques, various excellent electronic devices appear successively , Electronic components gradually from the era of the vacuum tube into the transistor era and large-scale, very large scale integrated circuit era. The formation of the anchor as a representative of the high-tech industry of the semiconductor industry.

 

       Because of the need of social development, electronic devices become more and more complex, which requires the electronic devices must be reliable, fast, low power consumption and light weight, miniaturization, low cost. Since the 20th century, put forward the idea of integrated circuits in the 1950s, due to material technology, device technology and circuit design and other integrated technology advances in the 20th century, 60 years successfully developed the first generation of integrated circuits. In the history of semiconductor development. The emergence of integrated circuits has epoch-making significance: the birth and development of copper core technology and computer advances, so that all areas of scientific research and industrial society has undergone a historic change in the structure. By virtue of superior science and technology invented the integrated circuit so that researchers have more advanced tools, resulting in a number of more advanced technology. These advanced technologies have further led to the emergence of higher performance, less costly integrated circuits. For electronic devices, the smaller the volume, the higher the integration; the shorter the response time, the faster the processing speed; the higher the transmission frequency, the greater the amount of information transmitted. Semiconductor industry and semiconductor technology is called the foundation of modern industry, but also has been developed as a relatively independent high-tech industry.

 

       Current Status of Electronic Components Industry

 

       China's electronic components production accounts for nearly 39% of the world. Production of the world's first products are: capacitors, resistors, electro-acoustic devices, magnetic materials, piezoelectric quartz crystal, micro-motor, electronic transformers, printed circuit boards.

 

       With the expansion of China's electronic information industry, the Pearl River Delta, the Yangtze River Delta, the Bohai Bay region, part of the central and western regions of the four major electronic information industry base initially formed. These areas of electronic information enterprise concentration, the industry chain is more complete, with considerable size and supporting capacity.

 

       China's electronic materials and components industry there are some major problems: the middle and low product surplus, high-end products mainly rely on imports; the lack of core technologies, product profit is low; small-scale enterprises, technology development investment.

 

       Development Trend Analysis of Electronic Components

 

       The State Council issued the "Twelfth Five-Year" National Strategic Emerging Industries Development Plan ", and strive to make strategic emerging industries in 2015 as a share of gross domestic product (GDP) from less than 4% in 2010 to 8% , By 2020 the proportion of the fight for 15%. Meanwhile, the "second Five-Year" period, a new generation of information technology industry sales revenue an average annual growth of more than 20%. The "next generation of information technology" includes: ultra-high-speed fiber and wireless communications, Internet of things, cloud computing, digital virtual, advanced semiconductor and new display. Among them, the core industries related to the electronics industry are: integrated circuit product design, advanced and characteristic chip manufacturing process technology, advanced packaging, testing technology and key equipment, instruments, a new generation of semiconductor materials and device technology.

Thus, the next three to five years, is the golden age of the development of electronic components industry, a national policy of good support, while scientific and technological progress will promote the electronic components industry to a deeper level of development. main performance:

 

       First, in the integrated circuit design, the integration of domestic chip and software applications to strengthen. Looking forward to 2015, IC design industry output value of the domestic market share increased from 5% to 15%.

       Second, in display technology, to actively and orderly development of large-size membrane transistor liquid crystal display (TFT-LCD), accelerate the organic light-emitting diode (OLED), three-dimensional (3D), laser display technology and other new generation display industry research and development .

       Third, in the LED industry, capture LED, OLED industry, common key technologies and key equipment to improve the LED, OLED lighting economy.

       Fourth, in the new components, the master intelligent sensors and new power electronic devices and systems of the core technology to improve the emerging field of special equipment, equipment support and support capabilities, the development of chip, miniaturization, green new components.

 

       In summary, in the next few years, the development of electronic components industry worthy of attention, which is closely related to our lives and a high-tech industry, it will shine in the next few years.
