Features of High Frequency PCB
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.
Minimize the size of your land patterns
One thing that you will notice with High Frequency PCB is that they have a smaller pad than the rest of the PCBs.
Actually, minimizing the space of your PCB is key to ensuring that you have a useful PCB.
On a general note, you can maintain the size of your Pad to be between 0 to 5% the size of the component pins. Other PCBs have a capacity of 30% of the component pins.
There are several advantages of minimizing space. It will maximize the mechanical strength as well as reduce the parasitic capacitance
Also, by reducing the space, you will have more space for differential pairs and high pin count space for your PCB.
