With the rapid development of the communication age, it can be said that every 10 years is a communication era. From 2G in the 1990s to 4G in 2010, the network is constantly upgrading, because the demand for high-performance mobile communication services has not been fully met. In order to realize the leap from communication to personal application, the transition from 4G to 5g is the most important change in the history of communication. As the next generation mobile communication network, the maximum theoretical transmission rate of 5g network can reach 10 GB / s, which is 100 times of the existing 4G network. It takes only a second to download the entire HD movie. The arrival of 5g network will change the world again and lead to great changes.
As a new generation of mobile communication technology, 5g is accelerating the development in the global scope. 154 operators in 66 countries plan to invest in 5g technology. In addition to China, South Korea, Japan and the United States, the United States is also actively building 5g networks. On December 27, 2018, the National Conference on industry and information technology proposed that the commercial deployment of 5g should be accelerated in 2019, and the standards, R & D, testing and security support work should be downward. In the 5g era, wireless signals will be extended to higher frequency bands, and the density of base stations and the calculation of mobile data will be greatly increased. At present, the industry predicts that the number of 5g base stations will be twice that of 4G era. In addition, the number of small base stations used to solve the problem of weak coverage and blind spot coverage is about 10 times of that of small base stations. The number of high-frequency Printed circuit board used in 5g base station antenna will be several times that of 4G. The increase of IDC and communication base station will also bring great demand for high speed Printed circuit board.
Printed circuit board ushers in industrial transfer dividend
Printed circuit board (PCB) is a bridge connecting electronic components and connecting circuits. As the mother of electronic products, PCB is widely used in communication electronics, consumer electronics, computer, automotive electronics, industrial control, medical equipment, national defense, aerospace and other fields. It is an indispensable electronic component in modern electronic information products. In the current accelerated development environment of cloud technology, 5g network construction, big data, artificial intelligence, sharing economy, industry 4.0, Internet of things, PCB industry will become the basic force of the entire electronic industry chain.
In recent years, the downstream industry is more diversified. The product application scope covers communication electronics, consumer electronics, computer, automotive electronics, industrial control, medical devices, national defense, aerospace and other fields. And the development of downstream industries is interrelated and mutually promoting. On the one hand, the good development momentum of the downstream industry has laid the foundation for the development of PCB industry. The downstream industry constantly puts forward stricter requirements for high system integration and high performance of PCB products, and promotes the evolution and upgrading of PCB products towards the direction of "light, thin, short and small".
In recent years, the sales of Printed circuit board terminals have gradually increased, and terminal manufacturers have also increased the proportion of circuit board terminals. The corresponding rail terminals are limited due to the complicated installation and large volume. The sales volume is slow, and the performance is not as good as the circuit board terminal. It is believed that under the influence of 5g technology, there will be more micro terminals.
