3.0mm Teflon PCB Board


High Frequency PCB Built on 3.0mm PTFE DK2.2 With 1oz Copper and Hot Air Soldering 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.


The F4B series of high frequency materials predominantly comprises PTFE glass fiber cloth and ceramic-filled PTFE glass fiber cloth. This series is a cost-effective choice while also being dependable due to its consistent quality. It finds its use in various modern applications such as navigation, satellite communication, radar, and the latest technologies like 4G and 5G communications.
