What is the major of learning PCB board? What major does PCB board belong to? Some students must not understand this, so let's answer it for you below:

　　Mobile phone circuit design belongs to the major of electronic circuit design and technology.

　　Graduates majoring in electronic circuit design and technology can work in electronic factories or research institutes to engage in product design and production preparation of electronic circuits, precision graphics manufacturing, numerical control machining, process control of circuit manufacturing, testing of circuit manufacturing, and quality control of circuit manufacturing. Control work, and can also be engaged in the procurement and sales of electronic circuits and raw and auxiliary materials, and the assembly of chip components.

　　In the application of power electronic technology and various power supply systems, switching power supply technology is in the core position. For large-scale electroplating power supply, the traditional circuit is very large and cumbersome. If the high-speed switching power supply technology is used, its volume and weight will be greatly reduced, and the power utilization efficiency can be greatly improved, materials can be saved, and costs can be reduced. In electric vehicles and variable frequency drives, switching power supply technology is inseparable, and the power frequency is changed by switching power supply, so as to achieve near-ideal load matching and drive control. High-frequency switching power supply technology is also the core technology of various high-power switching power supplies (inverter welding machine, communication power supply, high-frequency heating power supply, laser power supply, power operation power supply, etc.).

　　What industry does circuit board manufacturing belong to?

　　Circuit board manufacturing belongs to the modern electronics industry.

　　Circuit boards are also known as: PCB boards, aluminum substrates, high-frequency boards, PCB boards, PCBs, printed circuit boards, flexible boards, flexible boards, etc.

　　The raw material of the circuit board: glass fiber, which can be seen in our daily life. For example, the core of fireproof cloth and fireproof felt is glass fiber. Glass fiber is easy to combine with resin. The fiber cloth is immersed in the resin and hardened to obtain a heat-insulating, non-bending PCB substrate - if the PCB board is broken, the edges are whitish and layered, which is enough to prove that the material is resin glass fiber.

　　Three major trends in the future development of the circuit board PCB industry

　　1. The demand for PCBs for electric vehicles has grown significantly. Driven by electrification and intelligent two-wheel drive, the automotive electronics market has expanded rapidly, maintaining an annual growth rate of more than 15% in recent years, which has also driven the automotive PCB board market to continue to grow.

　　2. The demand of the 5G communication industry is approaching. my country's 5G construction investment will reach 705 billion yuan, an increase of 56.7% compared with 4G investment. Compared with the 2G-4G communication system, 5G will make more use of the 3000-5000MHz and millimeter-wave frequency bands, and at the same time, the data transmission rate will be increased by more than 10 times. The construction of ultra-dense small base stations brought by 5G commercial use will bring a large number of high-frequency PCBs. need.

　　3. Smartphones have increased demand for FPC. In 2016, the global FPC market reached 85.2 billion yuan. FPC is thin and flexible. FPC applications include antennas, cameras, display modules, touch modules, etc. At present, Apple's annual FPC purchases account for about half of the global market. Each iPhone uses about 14-16 FPCs, and a single ASP is close to $30.
