5G circuit boards not only provide electrical connections for electronic components, but also carry complex functions such as digital and analog signal transmission, power supply, RF and microwave signals for electronic devices. High speed, high frequency, high density and large capacity are the important trend of PCB board development. 5GPCBA process is complex, including PCB board manufacturing process, component inspection, SMT patch assembly, DIP plug-in, PCBA detection and other important processes. The main features of 5G circuit board are as follows:

1.High density: In the design of mobile terminals, the higher space utilization of high-frequency board means stronger expansion ability. By saving space, you can use larger, higher-resolution displays, larger batteries, and more complex processors and components. All of these can enhance the functionality of the device and enhance the overall user experience.

2.High heating: there are "impedance" and "dielectric loss" in the signal transmission of the high-frequency board. With the increase of the high-frequency or high-speed digitalization of the signal and the power, the high-frequency board continues to heat. China's 5g commercial frequency band is mainly under 6GHz in the first phase, and will reach 24-30ghz in the later phase. With the continuous improvement of 5g transmission rate, the amount of data transmission will be greatly increased. In addition, the emergence of 3D video, cloud gaming, wireless charging and other applications, these factors will lead to a significant increase in the heating capacity of 5G communication terminals compared with the 4G era.

3.high frequency and high speed: 5g era circuit board generally tends to high frequency and high speed. Since 5G, iot and other applications will adopt higher frequencies, it will gradually rise from below 3GHz in the past to 6GHz or even 24-30GH22. Considering the high resonance frequency of 5g, more strict impedance control is required. Without a very precise form, the thin wires of the 5G high-frequency board are likely to increase the risk of signal attenuation coefficients and reduce data integrity.
