PTFE High Frequency PCB 1.5mm DK 2.65 PTFE RF Circuit Board with 3oz Copper Coating Immersion Gold
(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.
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 radar, navigation, satellite communication, 4G communications, 5G communications and the like.
PCB Specifications
| Layer count: | Double sided |
| Base material: | F4B DK 2.65 |
| Dimension: | 210 x 115mm |
