As we enter 2019, news about 5G technology continues to emerge. Whether it’s large-scale testing by carriers or the release of 5G smartphones by device manufacturers, these developments have filled people with anticipation for the commercial prospects of 5G. Recently, South Korea’s official launch of 5G services has further signaled the arrival of the commercial 5G era. The commercialization of 5G will bring enormous market opportunities to upstream and downstream industries. Among them, as one of the key components of electronic devices, what role will PCBs (printed circuit boards) play? What are the technical requirements for PCBs under 5G? How can domestic PCB companies make their mark amid the 5G wave?
1. 5G Presents Huge Market Opportunities for PCBs
PCBs are often referred to as the ”mother of electronic products.” They not only provide electrical connections but also perform critical functions such as the transmission of digital and analog signals, power supply, and the transmission and reception of radio frequency and microwave signals. Virtually all electronic devices rely on PCBs.
It is understood that every 1 yuan invested in PCBs can support the development of 30 yuan worth of end products. Therefore, the 5G era offers tremendous market opportunities for the PCB industry. According to forecasts, the direct economic benefits generated by 5G in 2020, 2025, and 2030 will reach 484 billion yuan, 3.3 trillion yuan, and 6.3 trillion yuan, respectively, while the indirect economic benefits will reach 1.2 trillion yuan, 6.3 trillion yuan, and 10.6 trillion yuan, respectively.
The development of 5G will encompass the construction of communication networks, terminal devices, and various application scenarios, all of which require large quantities of PCBs. For example, 5G will significantly increase the use of PCB hardware in 5G wireless base stations, transport networks, transmission networks, and core network infrastructure, including 5G RF boards, backplanes, high-speed network boards, server motherboards,Microwave Board, power supply boards, and so on. In addition, 5G terminal devices, such as cell phones and smartwatches, also need to be upgraded in tandem with communication technology, which will further increase the demand for PCBs. According to estimates, a single 5G base station requires twice as many PCBs as a 4G base station.
2. Technical Requirements for PCBs in 5G
However, while 5G has created market opportunities, it has also introduced higher and more stringent technical requirements, with metrics such as speed, integration, heat dissipation, frequency, and multilayer design all showing significant improvements over 4G.
In the deployment of 5G networks, full-spectrum access, Massive MIMO, and ultra-dense networks will be key technologies. The application of these technologies also poses challenges for PCBs. First, the RF units and antennas in base stations have undergone significant changes; the number of RF channels has increased, and PCB area has also grown. Second, to achieve ultra-dense network coverage, 5G will make extensive use of millimeter-wave bands such as 28 GHz and 39 GHz, which will significantly increase the demand for PCBs in high-frequency microwave base stations. Finally, under the 5G standalone (SA) network architecture, data transmission equipment—such as baseband units, network boards, backplanes, and servers—will place even higher demands on PCBs.
Therefore, PCB manufacturers need to continuously improve their technical capabilities to meet the demands of 5G technology. This includes research into high-frequency components, signal integrity, and simulation. At the same time, thermal management for PCB products has become particularly important, as high-power-density and high-power devices require better heat dissipation capabilities.
3. Pursue a Strategy of Differentiation
Unlike the contract manufacturing of standard products, PCBs are highly customized products that require a deep understanding of customer needs. Therefore, in the 5G era, PCB manufacturers need to gain a deeper understanding of customer needs, keep pace with technological and market trends, and provide customers with products that better meet their requirements.
PCB manufacturers need to strengthen technical communication with raw material suppliers, as products in the 5G era place higher demands on both raw materials and manufacturing processes. In addition, PCB manufacturers need to research new, highly thermally conductive materials to meet heat dissipation requirements.
In summary, 5G technology presents enormous market opportunities for the PCB industry, but it also imposes higher technical requirements. Only by continuously improving their technical capabilities, meeting customer needs, and actively collaborating with raw material suppliers can PCB manufacturers make their mark in the 5G era.
Conclusion
The rise of 5G technology has brought unprecedented market opportunities to the PCB industry, while also raising technical requirements. PCB manufacturers must strengthen their R&D efforts, keep pace with market trends, and gain a deep understanding of customer needs in order to succeed in the 5G era.
