Product Description

5G small cell circuit boards are crucial components in 5G networks, known for their higher integration, faster transmission speed, lower energy consumption, and better heat dissipation. As 5G technology continues to advance and become more widespread, the application scope of 5G small cell circuit boards will also expand, bringing more convenient and efficient network services to people’s lives and work.

Key Features of 5G Circuit Boards:

High Density: In the design of mobile terminals, higher space utilization in high-frequency boards means stronger expansion capability. By saving space, larger and higher-resolution displays, bigger batteries, and more complex processors and components can be used. All of these enhance device functionality and overall user experience.
High Heat Generation: In high-frequency board signal transmission, there are “impedance” and “dielectric loss,” which result in continuous heat generation as the signal frequency or high-speed digitization and power increase. The initial commercial frequency band of 5G in China is mainly concentrated below 6GHz, and it will reach 24-30GHz in the later stages. As the transmission rate of 5G continues to increase, the data transmission volume will greatly increase. Additionally, the emergence of applications such as 3D video, cloud gaming, and wireless charging will significantly increase the heat generation capacity of 5G communication terminals compared to the 4G era.
High Frequency and High Speed: Circuit boards in the 5G era tend to be high-frequency and high-speed. With applications like 5G and the Internet of Things adopting higher frequencies, it will gradually rise from below 3GHz to 6GHz or even 24-30GHz. Considering the higher resonance frequency of 5G, stricter impedance control is necessary. Without extremely precise forming, there is a significant risk of increasing the signal attenuation coefficient and reducing data integrity in the fine lines of 5G high-frequency boards.

Testing Methods for 5G Circuit Boards

ICT Testing: This involves testing the voltage and current values of test points on the PCBA board after power-on, without involving functional keys or input-output testing. It mainly includes circuit continuity, voltage and current values, fluctuation curves, amplitudes, noise, etc. ICT testing is more suitable for high-density and small-batch PCBA, using flying probe testing.

FCT Testing: Functional testing (FCT) refers to providing stimulus and load analog operational environments to the PCBA board to obtain various state parameters of the board and check whether the functional parameters of the board meet the design requirements.

Laser Inspection: Laser inspection is one of the commonly used PCB inspection technologies, and practical verification of PCB bare boards is feasible.

X-Ray Inspection: X-ray inspection mainly utilizes the differences in the absorption rates of X-rays by different substances to detect defects. It is mainly used for the detection of ultra-fine pitch and ultra-high-density circuit boards.
