At present, 5G is booming, and with the arrival of the 5G era, PCB, as the mother of the electronic industry and the carrier of all components, occupies the largest proportion and benefits the PCB industry in this chain.

　　The development of 5G cannot do without the construction of large-scale data centers, which will inevitably increase the number of servers. The development of servers cannot do without PCBs. Due to the huge traffic carried by data centers and the high requirements for transmission speed, the requirements for the number of layers and materials of PCBs will also become 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, and the demand for communication boards in 5G base station construction will be further stimulated. Firstly, the number of 5G base stations is much higher than the current 4G base stations, especially the coverage of a certain number of micro base stations in blind spot areas, which undoubtedly drives the demand for communication PCB boards. Secondly, due to the increase in 5G channels, higher requirements are placed on the area and number of layers of a single PCB. The area has increased from 15cm to 35cm, and the number of layers has also been upgraded from double-sided boards to around 12 layer boards. In addition, the value of 5G base stations is much higher than that of 4G base stations. The high-speed and high-frequency boards used in 5G base stations are priced at 5000 yuan/㎡, while the unit price of 4G base stations is only 2000 yuan/㎡. This shows that the PCB value of 5G base stations is 2.5 times that of 4G base stations, so the value of communication boards has significantly increased.
