As the basic material for electronic products, PCB is considered as the mother of electronic products, driving a grand market of far-reaching demands. Its applications include the fields of communication, computers, consumer electronics, and automotive electronics. Of these, communication and computers are recognized as the largest sectors of application for PCB, accounting for over 25%.

               Right now, the era of 5G is gradually approaching, and it will march into commercialization in 2019 and be officially commercialized in 2020. It is reported that various 5G application scenarios will require higher connection speeds, delay, and connection density. Besides, 5G radio frequency will introduce Massive MIMO (large-scale antenna array) technology, which will require the use of wider spectrum and bandwidth of millimeter wave-bands to carry out communication.
 

       Compared to the scale and number of million-level base stations required during the 4G era, the development of the millimeter wave will push the scale of base stations in the 5G era to exceed that of ten-million. It can, therefore, be foreseen that the mass construction and upgrading of communication base stations will create a huge demand for high-frequency and high-speed boards such as PCBs, along with the approaching full-scale commercialization of 5G, and a brand-new wave of needs to upgrade and replace PCB.
