5G is expected to greatly increase the demands of PCBs in telecommunication electronics

Telecommunication electronics is the most important downstream application area of the PCB industry, According to data from Prismark , telecommunication electronics accounted for 27.30% of the total output value of PCB in 2017, which is the biggest application field of the PCB industry.

PCBs has a wide range of applications in wireless networks, transmission networks, data communications, and fixed-line broadband, and is often a high value-added product such as backplanes, high-frequency high-speed PCBs, and multi-layer PCBs.5G is the next-generation mobile communication network, and there will be a large number needs for 5G infrastructure construction, which is expected to drastically drive the demand of PCBs in telecommunication electronics, that is, PCBs is needed in every link of telecommunication field

5G will bring major changes to the structure of the base station, and the usage and unit price of telecommunication PCBs are expected to increase substantially. In the 4G era, a standard macro base station is mainly composed of a baseband unit (BBU), a radio processing unit (RRU), and an antenna. Since the 10 Gbps transmission capacity of the conventional CPRI (the public radio interface connecting the RRU and the BBU) is not enough in the 5G era, in order to reduce the transmission bandwidth, the 5G base station structure needs to be reconstructed.

The antenna frame of the 5G base station needs to use the PCBs as a connection. Compared with the PCB of the 4G era, the PCB used by 5G will be upgraded in many aspects, resulting in a significant increase in usage and value.

The first is that the area and number of layers of the PCBs will be greatly improved.

Secondly, the base material of PCBs is to use high-frequency high-speed material, which brings a significant increase in the value.
