The high frequency PCB is a kind of PCB used for signal transmission in a variety of applications, including mobile, microwave, RF and high-speed design applications. High frequency boards with high frequency laminates are difficult to manufacture because they need to maintain the heat transfer of the application due to the sensitivity of the signal.


As the complexity of electronic components increases, the one thing that becomes imperative is signal rates and high frequency of transmission. As the signal flow rates grows, the demand for high frequency PCBs is on the rise. They find use in a variety of high-speed design applications that require a frequency range of 500MHz to 2GHz.

In this article, we will introduce you some tips of high frequency PCB.


Here is the content list:

1. First up, the benefit that high frequency PCBs offer is that they have high density and improved signals. This kind of PCB is suited for high-speed designs.

2. The use of the ground plane further enhances the quality of signals as also reduces the electromagnetic waves.

3. With the careful determination of the length and trace width of the board, excessive heating is prevented even at high frequencies.


1. First up, the benefit that high frequency PCBs offer is that they have high density and improved signals.

The high frequency PCB offers a frequency range of 500MHz-2GHz, making it suited for high-speed designs. The use of multi-layered PCBs and the right combination of materials enables designers to achieve small size, high functional density, improved signals, and all this at reduced costs. The design of high frequency PCBs is similar to multilayer PCBs and they are made of Rogers, FR4 material or materials such as Teflon, ceramic, and polyimide among others with good dielectric properties are used for substrates.


2. The use of the ground plane further enhances the quality of signals as also reduces the electromagnetic waves.

They work well in reducing circuit impedance and provide a shielding effect. With the reduced distance between plane and trace layer, crosstalk is avoided. High-frequency circuit boards are widely used in various fields where require precision metal heating treatment. In the process of the field of high frequency PCB, it can not only control the temperatures of different depth components, but also focus on heating according to local characteristics, whether it is surface or level. High frequency PCBs can easily complete the method of centralized or decentralized heating.


3. With the careful determination of the length and trace width of the board, excessive heating is prevented even at high frequencies.

Skin effect occurs due to the resistance of traces, and it increases the temperature of the board. Hence, we ensure that the length and trace width of the board is selected such that they don’t heat the board at high frequencies.


What’s more, humid weather will seriously affect the use of circuit boards. High-frequency circuit boards made of materials with very low water absorption can tolerate such an environment. At the same time, high-frequency circuit boards also have the advantages of resistance to chemical corrosion, moisture, high temperature and great peel strength, allowing high-frequency circuit boards to exert powerful performance.
