PCB Technical - Exciting PCB printed circuit boards in the 5G era

PCB (PrintedCircuitBoard), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed" circuit board

PCB circuit boards are mainly used in communications, automotive electronics, consumer electronics and other fields. Among them, computers and communications are the main downstream markets. This is also the reason why multi-layer boards still occupy a large market share.

As the basic industry of the electronics industry, its development direction is determined by the development direction of downstream industries. The strongest voice of the downstream industry in the future is undoubtedly 5G, smart phones, and automotive electronics.

The evolution of each generation of communication technology has not only brought new ways of communication and collaboration to mankind, but also gave birth to unimaginable business forms in the past.

The 4G era ushered in new industries and new models such as mobile payment, online video, food delivery, and the sharing economy. The brilliant mobile Internet era was started by 4G.

For the time being, people can only imagine that 5G can promote the rapid development of industries such as AI, virtual reality, and autonomous driving, but just these few fields are enough to detonate all parties' imaginations about the future.

In the 5G era, wireless signals will extend to higher frequency bands. Since the coverage area of base stations is inversely proportional to the communication frequency, the density of base stations and the amount of mobile data calculations will increase significantly.

The industry currently predicts that the number of 5G base stations will reach twice that of the 4G era.

In addition, there are about 10 times the number of small base stations to solve the problem of weak coverage and coverage blind spots.

The amount of high-frequency PCB used for 5G base station antennas will be several times that of 4G, and the increase in IDC and communication base stations will also bring huge demand for high-speed PCBs.

In addition to the increase in the number of base stations, the value of a single base station PCB board will also increase significantly.

As the 5G communication frequency band increases, the number of RF front-end components, the area of the PCB board, and the number of layers will also increase.

The larger area, more layers, and the use of high-frequency and high-speed substrates have shifted the value of base station antennas to PCBs.

The PCB value of a single macro base station can reach twice that of the 4G era.

According to estimates, the number of newly built 5G communication base stations will reach 8-9 million, and the PCB value of a single base station will be between 20,000 and 40,000, which will bring hundreds of billions of market to communication PCBs.

Therefore, with the arrival of the 5G wave, the local PCB industry will usher in a golden age in the next few years.
