What is the relationship between PCB multi-layer circuit boards and 5G

The current 5G boom and the arrival of the 5G era,PCB multilayer circuit boards are the mother of the electronics industry and the carrier of all components. The PCB industry has the largest proportion and the most benefit in this chain.

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 the number of 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 circuit boards for a single base station will also be greatly increased, and the demand for communication boards in the construction of 5G base stations will be further driven. First of all, the number of 5G base stations is much larger than that of current 4G base stations, especially in blind spot areas that will cover a certain number of micro base stations, which will undoubtedly drive the demand for communication circuit boards. Secondly, due to the increase in 5G channels, the area and number of layers of single-chip PCB multi-layer circuit boards are higher. 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 (multi-layer circuit boards) . 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 5000 yuan/㎡, while the unit price of 4G base stations is only 2000 yuan/㎡. It can be seen that the PCB value of 5G base stations is 4G. 2.5 times that of the base station, so the value of the communication board has been greatly improved.

According to Prismark's forecast, the compound growth rate of the PCB 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, PCB 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 products and services to different customers.
