FR4 circuit board, how to distinguish Between Ordinary PCB And High Frequency PCB?
The high-frequency printed circuit board is pressed with a whole piece of epoxy glass cloth, and the color of the high frequency circuit board is relatively uniform and bright; at the fracture, you can easily see the white powder with the color of rice by scraping it with your hand or other tools. White. The density is higher than that of ordinary FR4 pcb, and the weight is heavier.

Ordinary FR4 PCB is made of glass fiber board (composite board). The color of the back substrate is different. Large stripes can be seen on the back of the entire board. Check for different types of PCBs.

What Failure Phenomenon Will Occur When The Performance Of The High-Frequency Printed Circuit Board Is Poor
The poor performance of the high-frequency printed circuit board is mainly due to the low dielectric constant value which affects the working stability of the high-frequency circuit. It may cause signal attenuation, frequency offset drift, and severely stop vibration. The overall electrical performance index is reduced.

Materials Used for High Frequency PCB
Here are the common materials used for High Frequency PCBs:

FR-4:This is the most common material used for PCBs in general, and it can also be used for some high-frequency applications. It is a laminate made of woven fiberglass cloth impregnated with an epoxy resin. FR-4 is relatively inexpensive and has good electrical properties, but it starts to become lossy at higher frequencies (above a few GHz).
PTFE (Polytetrafluoroethylene):Also known as Teflon, PTFE is a very low-loss material that is ideal for high-frequency applications. It has a very high dielectric constant (Dk) and low dissipation factor (Df), which means that it will not attenuate signals as much as other materials. However, PTFE is more expensive than FR-4 and can be more difficult to machine.
High-frequency laminates: There are a number of other laminate materials that are specifically designed for high-frequency applications. These materials typically use ceramic fillers or other additives to improve their high-frequency performance. They offer a good balance between cost, performance, and ease of manufacture.
Metal core PCBs:Metal core PCBs are a type of high-frequency PCB that uses a metal core, such as aluminum or copper, sandwiched between two layers of dielectric material. Metal core PCBs offer excellent electrical performance, but they are also the most expensive type of high-frequency PCB.
The choice of material for a high-frequency PCB will depend on a number of factors, including the frequency of operation, the required signal integrity, the cost, and the ease of manufacture.
