What is High Frequency PCB?
High frequency refers to a type of printed circuit board whose applications is common in devices that requires transmission of particular signals between objects.
Mostly, the frequency range of these High Frequency PCB is between 500MHZ to 2GHz.
The most common applications that use this PCB include microwaves, mobile phones, and radio frequency.
High-Frequency PCBs usually have High-frequency laminates which are hard to fabricate. This is because they need to retain the thermal heat transfer of the application.
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.
Controlled Impedance applied into high frequency PCB
The design of controlled impedance line is to avoid the signal loss, there are two kind of method to set controlled impedance, that is microstrip and stripline: to support better result, the existence of the trace on the outer layers that come with a ground plane below must be closer to the outer layers. Stripline is better as compared to microstrip because it has an ability to contain radiation and signal.
