5G PCB Has Fully Exploded And Ushered in New Growth Momentum

Jan 15, 2021

PCB refers to a printed board on a general base material that forms connection between points and printed components according to a predetermined design. Its main function is to make various electronic components form a predetermined circuit connection, which plays a role of relay transmission and is an important electronic component. It is the support of electronic components and the carrier of electrical connection of electronic components.

With the iteration of 5G technology, the product structure of PCBs has also differentiated. Multilayer boards still occupy the mainstream position in the PCB market. With the rapid development of electronic circuit industry technology, the integrated functions of components are becoming more and more extensive, and electronic products have more high-density requirements for PCBs. In order to highlight, high-end PCB products such as high-multilayer boards, flexible boards, HDI boards and packaging substrates have gradually occupied a leading position in the market. With the development of electrification and automation in human society, the desire for mobile devices and progressive "smart" digitization will further increase, and the application range of PCBs will become more and more extensive, and at the same time, it will bring new momentum to the PCB industry.

The downstream of the PCB industry covers almost all electrical circuit products, and the core application areas include communication equipment, computers, consumer electronics and automotive electronics. At present, the communications field is the largest downstream of PCB, and the communications market accounts for about one-fifth of the global output of electronic products, which includes mobile and fixed devices and their infrastructure. In particular, mobile devices have driven the demand for rigid, flexible and flexible substrates. PCBs are mainly used in the communication field in transmission networks, wireless networks, data communications, and fixed broadband equipment. The 5G base station is characterized by high frequency and high speed, which requires the use of millimeter waves with higher frequencies and wider bandwidths. Band (frequency from 30GHz to 300GHz). Because millimeter waves belong to the extremely high frequency range, the transmission characteristics of electromagnetic waves are that the higher the frequency, the shorter the wavelength, the weaker the diffraction ability, and the stronger the penetration ability. However, the signal penetration process will lose a lot of energy, which leads to the shorter the transmission distance. To solve the problem of serious signal attenuation, the only way to increase the number of 5G base stations is to increase the number of 5G base stations and 5G electronic equipment. The increase in 5G base stations and 5G electronic equipment has led to a sharp increase in PCB demand, which will bring broad market space to PCB and strongly promote the rapid development of the PCB industry. 5G has become the new main force driving the growth of PCB business.
