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 |
| Finished thickness | 1.6mm ±10% |
| Finished Copper weight: | 3oz |
| SMOBC: | No |
| Surface finish: | Immersion gold |
The main specifications of this board is double sided board, substrate is F4B, DK at 2.65, 210mm long by 115mm wide, 1.6mm finished thick, finished copper 3oz, no solder mask no silkscreen, and surface finish is immersion gold.
Let’s see the stack up.
Top layer and bottom layer are 3oz copper finished. F4b dielectric material is in the middle of 2 layers copper, showing dielectric constant at 2.65.
From the photo of this board, the track is thicker than normal boards; surface finish is immersion gold and no solder mask and silkscreen.
