F4B High Frequency PCB DK 2.2 PTFE PCB with 3.0mm Thick 1oz Copper
and HASL Lead Free for Patch Antenna
(PCB's are custom-made products, the picture and parameters shown
are just for reference)
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.
