What is the relationship between 5G and multilayer circuit boards

At present, 5G is hot. With the advent of the 5G era, PCB, as the mother of the electronics industry, is also the carrier of all components. The PCB industry has the largest proportion and the most benefit in this chain. So, what is the relationship between 5G and multilayer circuit boards?

The development of 5G is inseparable from the construction of large-scale data centers, which will inevitably increase servers. The development of servers cannot The requirements for PCB layers and materials will also become higher and higher. In this case, the demand for high-end communication boards will be greatly increased.

With the continuous advancement of 5G construction, due to the high-speed and high-frequency characteristics of 5G, the value of communication boards for a single base station will also be greatly increased. The construction of 5G base stations will further drive the demand for communication circuit boards. First of all, the number of 5G base stations is much more than the current 4G base stations, especially in blind spot areas will cover a certain number of micro base stations, which undoubtedly stimulates the demand for communication PCB boards (multilayer circuit boards). Secondly, due to the increase in 5G channels, there is a higher requirement for the area of single-chip PCB circuit boards and the number of layers of multi-layer circuit boards. The area has been increased from 15cm to 35cm, and the number of layers has also been upgraded from double-sided circuit boards to 12-layer boards (multilayer Circuit board) around. In addition, the value of 5G base stations is much higher than that of 4G base stations. The unit price of high-speed and high-frequency plates used in 5G base stations is 5,000 yuan/㎡, while the unit price of 4G base stations is only 2,000 yuan/㎡. This shows the value of PCB circuit boards for 5G base stations. It is 2.5 times that of 4G base stations, so the value of communication PCB boards has been greatly improved.

According to Prismark's forecast, the compound growth rate of the PCB multilayer circuit board industry will reach 3% from 2016 to 2020, that is, the output value in 2020 will approach US$60 billion. In the current environment of rapid development of cloud computing and 5G, PCB is an important basic force in the entire electronic industry chain, and the ever-changing environment drives the new direction of PCB demand growth. Therefore, circuit board manufacturers should continue to invest resources in PCB engineering research and development, actively practice intelligent production management, steadily improve the level of production automation, and achieve a strong ability to provide a full range of PCB multi-layer circuit board products and services for different customers.
