Electronic Production Workshop

The production process for electronic products is generally like this:

1, components into the factory inspection, PCB board into the factory inspection
2, component molding treatment, molding to facilitate the insertion.
3, SMT patch, after reflow welding, the SMD device affixed to the PCB.
4, from the SMT out of the circuit board for manual insertion. It is mainly a perforated device that cannot be pasted.
5, hand-plugged after wave soldering, and then need to carry out welding shaping, commonly known as two times plug.
6, after two plug can be tested.
7, the test generally has three steps: initial test, (assembly), aging, complex measurement.
8, the final inspection and packaging.

Electronic products are based on electrical energy related products, mainly include: watches, smartphones, telephones, televisions, DVD players (VCD, SVCD, DVD), video recorders, camcorders, radios, recorders, combination speakers, CD players (CDs), computers, mobile communications products and so on. Because the early products are mainly based on the electronic tube of the original so famous electronics.

Electronic technology is a new technology developed by Western countries such as Europe and the United States in the late 19th century and early 20th century, starting with the American Morse Invention Telegram of 1837, the 1875 American Alexander Bell invented the telephone, and in 1902 the British physicist Fleming invented the electron tube. Electronic products in the 20th century the most rapid development, the most widely used, has become an important symbol of the development of modern science and technology.

The first generation of electronic products with electron tubes as the core. In the late 40, the world was born the first semiconductor transistor, it is small, lightweight, power saving, long life and other characteristics, quickly used by countries, in a large range of the replacement of electronic tubes. In the late 50, the world appeared the first integrated circuit, which integrates many electronic components such as transistors into a silicon chip, allowing electronic products to develop to a smaller level. Integrated circuits from small-scale integrated circuits rapidly developed to large integrated circuits and VLSI, so that electronic products towards high efficiency low consumption, high precision, high stability, intelligent direction of development.
