In modern electronic equipment, high-frequency PCB boards are widely used and are also an indispensable part of many high-frequency devices. Most of them are used in applications with relatively strict requirements for high-frequency PCB boards .
    Application fields of high-frequency PCB boards:
　　1. Mobile communication products;
　　2. Power amplifiers, low-noise amplifiers, etc.;
　　3. Passive devices such as power dividers, couplers, duplexers, filters, etc.;
　　4. In the fields of automotive anti-collision systems, satellite systems, radio systems, etc., high-frequency electronic equipment is a development trend.

　
2. Selection of PCB boards in high-frequency PCB board manufacturing
　　Nowadays, there are many brands and models of PCB boards on the market. How to choose the right PCB board in the manufacturing of high-frequency PCB boards? This is also a very critical factor. The performance parameters of high-frequency PCB boards manufactured by different PCB boards are also different.
　　Good high-frequency boards have the following characteristics:
　　1. High-frequency PCB boards need to be resistant to high temperature, high pressure, moisture, etc., so PCB boards with low water absorption need to be selected. PCB boards with low water absorption have better hydrolysis resistance, which can effectively reduce the impact of moisture on the circuit and improve the reliability of high-frequency PCB boards.
　　2. High-frequency circuit boards need to use materials with good conductivity and low dissipation factor. This material not only has good conductivity, reliability and stability, but also has excellent corrosion resistance and wear resistance.
       3. The thicker the copper foil of the high-frequency PCB board, the faster its transmission speed. However, the thickness of the high-frequency PCB board also needs to match the thickness of the copper foil. If the thickness of the copper foil is too large, it is easy to cause problems such as circuit board breakage or interface breakage. Therefore, when selecting PCB board materials, the thickness of the copper foil and the thickness of the circuit board need to be taken into account.
　　4. When selecting PCB board materials, the balance between cost and performance needs to be considered. PCB board materials can be selected according to the requirements and budget of high-frequency PCB boards to achieve the best cost performance.
