2022 On January 18, the Chinese Academy of communications and communications released the analysis report on the operation of the domestic mobile phone market in 2021. According to the data, in 2021, the total shipments of mobile phones in the domestic market totaled 351 million, with a year-on-year increase of 13.9%. Among them, the shipments of 5g mobile phones were 266 million, with a year-on-year increase of 63.5%, accounting for 75.9% of the mobile phone shipments in the same period; Smartphone shipments reached 343 million, up 15.9% year-on-year, accounting for for 97.7% of mobile phone shipments in the same period.

With the accelerated deployment of 5g commercialization, 5g mobile phones have become a new driving force for the growth of the global smartphone market, driving the overall recovery of the smartphone market. As an indispensable part of mobile phones and peripheral products, the recovery of the smartphone market has not only expanded the market scale of connectors. It is understood that the applications of mobile phones and peripheral connectors mainly include:

Internal connector: 1) FPC connector: rear fingerprint identification module connecting line, main and auxiliary board connecting line, mobile phone screen driving circuit (PCB) connecting line; 2) Board to board connection: connect PCB board to realize electromechanical connection; 3) Wire to board connector;

External connector: 1) earphone interface; 2) I/O connector, power, and signal connection, circular connector, min Iusb connector, MicroUSB connector, USB type-c interface, etc.3) Battery connector: shrapnel type (detachable battery) and knife switch type, FPC + BTB (non-detachable battery); 4) SIM card connector: the SIM card connects and communicates with relevant circuits in the machine; 5) Memory card connector; 6) Antenna / RF connector, including RF coaxial transmission line + RF coaxial connector; 7)cameraSocket.

In the context of the continuous evolution of mobile Internet applications, mobile phones are developing towards light, multi-functional, and high-performance, and also lead the development of connectors to high-speed, micro, and high-performance.

Taking the data transmission application as an example, from the maximum transmission speed of early USB1.1 to USB2.0, the maximum transmission speed is 480mbps. In usb3.1gen2, the transmission speed is increased to 10Gbps, and its communication mode is also improved from semi-dual to full dual to meet the requirements of high-speed transmission. The launch of the new generation USB4 will increase the data transmission capacity to 40Gbps. In addition, the 5g era has come, mobile broadband has been enhanced, and the transmission speed is 100 times that of 4G. This requires upgrading the performance of the connector to meet the requirements of high frequency and high speed of downstream products.

In addition to the improvement of speed, the development trend of consumer electronic products makes the appearance size of connectors smaller and smaller. From the development of USB, driven by smartphones, micro-series products were developed in 2007 to meet the needs of mobile communication, from widely used standards a and Btype to mini-series. At present, the appearance size of USB type-c has been reduced by six times.

While developing towards miniaturization, it puts forward higher requirements for the precision manufacturing technology of upstream manufacturers. At present, the contact spacing of standard connectors is 0.3mm and is developing toward higher accuracy.

The introduction of new functions, new applications, intelligence, and thinness of mobile phone products make the number of connectors increase synchronously. At the same time, the internal structure design of the terminal product is more compact, the level and accuracy are improved together, and the performance and quality requirements of the connector are also improved accordingly, so as to drive the improvement of the function and value of the whole connector product.

BTB connectors are mainly used for mobile phone displays, main and auxiliary boards, fingerprint identification, speakers, headphones, etc. the consumption of iPhone xsbtb connectors reaches 15 pairs, and the consumption of Android machines reaches about 10 pairs.

The popularization of multi camera technology will promote the market demand of BTB connectors. It is expected that the design of three or four cameras will add 1-3 pairs of BTB connectors to a single mobile phone. The new horizontal linear motor needs to be fixed by BTB connector, and FPC fixes the pressure button through BTB connector. Mobile phone brand touch upgrade is expected to increase the number of BTB connectors for a single mobile phone by about 2 pairs.

Generally speaking, the lightweight, multi-function, and high performance of smartphones promote the new development of connector technology. The development and application of 5g technology further enhance the strength of the connector industry, and also improve the sales unit price and price rise of connector products. It is expected that the connector market will enter a new round of growth.
