How long does it take to apply for the electrician IC electrician certificate in Shilong, Dongguan in 2016? Are there good training institutions?

IC(rr,). It concentrates a large number of components, such as resistors, diodes, transistors, etc., including the connections between them, on a small piece of semiconductor silicon. On a silicon chip, dozens to hundreds of thousands of components can be accommodated to form a powerful circuit system. Semiconductor technology is improving day by day. The integrated circuits that appeared in the 1990s marked the electronic technology. Integrated circuits are not only small in size, low in quality, low in cost, and low in energy consumption, but also have high reliability in circuit operation and are easy to assemble and debug. They have been It is widely used in various fields such as electronic computers, electronic equipment and household appliances. It should be noted here that there are many types of semiconductor integrated circuits, among which operational amplifiers and digital integrated blocks are widely used. It is covered extensively in both analog electronics and digital electronics courses. This project mainly introduces power integrated circuits and time-based circuits that are widely used in the field of electronic technology.

The so-called analog integrated circuits are used for An integrated circuit that processes analog signals, which are changing signals. Analog integrated circuits are widely used in various audio-visual equipment. Even though radio cassette recorders, televisions, audio equipment, etc. have a good reputation as "digital equipment," they are inseparable from analog integrated circuits.
