In the field of communication PCB, it is widely used in wireless networks, transmission networks, data communications, and fixed-line broadband. Related products involve backplanes, high-speed multilayer boards, high-frequency microwave boards, and multifunctional metal substrates.

　　The current situation of the communication circuit board industry

According to relevant data, the communication PCB market reached US$19.06 billion in 2018, accounting for about 30% of the total PCB output value. Is 5-10%.

　　 From 4G to 5G industry development prospects

According to the relevant calculations of the brokerage firm, the PCB usage of a single 5G base station is about 3.21 square meters, which is 1.76 times the consumption of 4G base stations (1.825 square meters). At the same time, because the frequency of 5G communication is higher, the demand for PCB performance is greater, so 5G The unit price of PCB for base station is higher than that for 4G base station. Taken together, the value of PCB for a single base station in the 5G era is about three times that of the 4G era.

In addition, due to the higher frequency spectrum of 5G, the coverage of base stations is smaller. According to estimates, domestic 5G base stations will be 1.2-1.5 times that of 4G base stations. At the same time, more small base stations are required. Therefore, the base stations brought by 5G The total number will be much more than that of 4G. It is estimated that the newly added 5G macro base stations in China during the peak of 5G construction in 2023 will be 1.5 times the peak of 4G construction in 15 years. Based on comprehensive calculations, we believe that the market size of the communication PCB industry for base stations in the next few years is about 5 to 26 billion. Compared with the market of 5 to 9 billion in the 4G era, the PCB industry for base stations is undoubtedly an explosive growth in the past few years.
