The difference between high frequency PCB and ordinary board​

High-frequency and high-speed PCB boards, as printed circuit boards with frequencies exceeding 1GHz, may have different definitions in the industry. However, this type of board is known for its excellent physical properties, high precision and strict technical parameter requirements, and is widely used in cutting-edge fields such as communication systems, automotive ADAS systems, satellite communications and radio systems.

High Frequency PCB

In addition to RF systems, modern devices also cover digital processing and interface parts. Driven by consumer demand for faster Internet connections, mobile HD video and the Internet of Things, PCB boards must not only meet high-frequency performance, but also support high-speed digital data transmission. Commercial applications such as IoT, 5G, and big data centers, as well as an increasing number of personal applications, are constantly refreshing the speed requirements of digital communication systems. According to statistics, driven by data rates, the bandwidth of high-speed digital systems doubles almost every three years.

Although the production process of high-frequency and high-speed PCB boards is similar to that of ordinary PCB boards, the core difference lies in the properties of their raw materials. The main material used in high-frequency and high-speed PCB boards is high-frequency and high-speed copper clad laminate, which has a low dielectric constant (Dk) and a low dielectric loss factor (Df). These two parameters are crucial to ensure the speed and quality of signal transmission.

Type High Frequency PCB Ordinary PCB
Dielectric constant (Dk) High-frequency and high-speed PCB boards require the dielectric constant of the substrate to be small and stable, because the signal transmission rate is inversely proportional to the square root of the material dielectric constant. High dielectric constants can easily cause signal transmission delays. In contrast, ordinary PCB boards have relatively low requirements for dielectric constants and focus more on meeting general circuit connection needs.
Dielectric loss factor (Df) High-frequency and high-speed PCB boards require that the dielectric loss of the substrate must be small to reduce attenuation and heat generation during signal transmission. Ordinary PCB boards have relatively low requirements in this regard.
Impedance characteristics One of the basic principles of high-speed design is impedance control, and high-frequency and high-speed PCB boards have strict requirements for this to ensure the stability and integrity of signal transmission. Ordinary PCB boards usually have looser requirements for impedance control.
Water absorption High-frequency and high-speed PCB boards require low water absorption of the substrate to prevent changes in dielectric constant and dielectric loss when wet. Ordinary PCB boards usually have lower requirements in this regard.
