The simple way of understanding High Frequency PCBs is by understanding its features.The features give you an idea of what a High Frequency PCBs are.To avoid any delay in the transmission of the frequency signal, the DK needs to be smaller and stable. Actually, the lower it is, the better for efficient frequency transmission.The DF needs to be small since it affects the quality of the transmission of the signal. If possible, use a smaller DF for clear signal transmission.To avoid separation of the copper foil when there is temperature change, you need to check on the thermal expansivity of the PCB.
For effectiveness, you need to ensure that the thermal expansivity of the PCB materials is the same as that of the copper foil.Ensure that the heat resisting property, impact endurance, chemical resistance and peel of resistance needs to be appropriate.
High speed and high frequency pcb is different. High-speed circuit refers to that the voltage rises or falls in a short period of time, and High Frequency circuit refers to that the circuit has a short period. But there is no exact difference between a high-speed PCB and a High Frequency PCB. Even the basic materials are the same. So if you ask the difference between high-speed PCB and High Frequency PCB, ignore the name of the circuit board, and focus on how to maintain the signal integrity of the circuit.

Characteristics of High Frequency PCB Laminate Material
Understanding the characteristics of your High Frequency PCB
laminate material is critical when manufacturing your PCB.
Dielectric constant (Er)
You will be able to identify and understand the behavior of your
PCB.
Dielectric constant is a measure of the ability of a material to store electrical energy while in an electric field.
This ability depends on the direction of the current implying that the dielectric current changes as the axis of the material changes.
What you need to understand is the frequency range that you will subject the material to while testing.
Also, you need to know the testing method and any variable present for the frequency range.
Lastly, you have to consider the constant dielectric conditions of your PCB that can match that of your application.
