F4B High Frequency PCB with 3.0mm Thick
Hello everybody,
Today we talk about a type of F4B high frequency circuit board at 3.0mm thick.
F4B series high frequency material is mainly PTFE glass fiber cloth and ceramic-filled PTFE glass fiber cloth etc. It is a series of high frequency materials of Chinese brand, which is cheap in price and stable in quality. It's widely applied to satellite communication, navigation, radar, 4G communications, 5G communications and the like.
