1, product categories, species complex. Only according to the electronic product classification and code of electronic ministry compiled statistics, electronic components in integrated circuit products other than there are 206 major categories of 2519 kinds, including electric vacuum device in 13 major categories of 260 kinds; discrete semiconductor devices (including laser, optoelectronic devices such as) 18 categories and 379 types of electronic; elements of 17 professional, 161 categories and 1284 types of. Electronic materials have 14 categories and 596 types of.
2, professional and strong, and multidisciplinary collection, production technology and production equipment, testing equipment and technology, great differences. This is not only the difference between electric vacuum device, semiconductor devices, electronic components, each in each industry big category, even small classes are also differences, such as different display devices, different elements, different capacitor, resistor, sensitive components are also different, of course, the similar products of different stage, also need different production technologies and methods, it is a kind of electronic components have a production line, a generation of components is a generation of production line; some professional such as the production of multilayer printed circuit board of the enterprise need to add new equipment every year.
3, complete and series. This is composed of an electronic circuit, the band and frequency characteristic, function, accuracy, power, storage and use of the conditions and environment, the service life of the requirements to decide.
4, investment intensity differences, different time difference is also great, especially the production scale, the rate of finished products is different, different requirements for production conditions, production environment. Which belongs to the high tech, and the need for mass production products its investment scale than the "eight five period" has been increased by an order of magnitude, often up to billions of dollars, the lowest at 000000; and for other products, the technical difficulty is high, limited production, equipment automation is relatively low, the investment intensity is small much.
5, each kind of electronic components and its industry has its different development, but they and electronic machine, system development, including electronic technology, development is closely related to structure, electric machine loading technology, become the one one corresponding relationship. But in industrial development, both between electronic devices and the whole system, or between various types of electronic components, is mutual promotion, mutual restriction. The new electronic components reflects the contemporary and future of electronic components in high frequency, chip, miniaturization, thinness, low power consumption, response trend rate, high resolution, high precision, high power, multi function, component and composite, modular, intelligence, environmental protection and energy saving.
