What is a high frequency PCB board

High frequency PCB boards are special circuit boards with higher electromagnetic frequencies. Generally speaking, high-frequency can be defined as frequencies above 1GHz. Its various physical properties, accuracy, and technical parameters require very high requirements, and are often used in automotive anti-collision systems, satellite systems, radio systems and other fields.

With the rapid development of science and technology, more and more equipment designs are applied in the microwave frequency band (>1GHZ) and even in the millimeter wave field (30GHZ), which also means that the frequency is getting higher and higher, and the requirements for the circuit board are getting higher and higher. For example, the substrate material needs to have excellent electrical properties, good chemical stability, and the loss on the substrate with the increase of the power signal frequency is very small, so the importance of the high-frequency PCB board is highlighted.

Advantages of high frequency PCB board

1. High efficiency

High-frequency PCB boards with small dielectric constants will have very low losses, and advanced induction heating technology can achieve the target heating requirements with very high efficiency. Of course, while focusing on efficiency, it also has the characteristics of environmental protection, which is very suitable for the development direction of today’s society.

2. Fast transmission speed

The transmission speed is inversely proportional to the square root of the dielectric constant, which means that the smaller the dielectric constant, the faster the transmission speed. This is the advantage of the high-frequency printed circuit board. It uses special materials, which not only guarantees the low dielectric constant, but also maintains the stable operation, which is very important for signal transmission.

3. Large degree of controllability

High frequency PCB board is widely used in various industries that require precision metal material heating treatment. In the process of its field, not only can heating of different depth components, but also focus on heating according to local characteristics, whether it is surface or deep level; centralized or decentralized heating methods can be easily completed.

4. Strong tolerance

Dielectric constant and medium have certain requirements on the environment, especially in the south, where wet weather will seriously affect the use of circuit boards. High-frequency circuit boards made of materials with extremely low water absorption can challenge such an environment. At the same time, they 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 .

Applications of high frequency PCB board

  1. Mobile communication products.
  2. Power amplifier, low noise amplifier, etc.
  3. Passive components such as power splitters, couplers, duplexers, filters, etc.
  4. Automobile anti-collision systems, satellite systems, radio systems and other fields.
