Wangling’s F4BM high frequency DK (dielectric constant) options spanning from 2.17 to 3.0
What circuit boards do we do? (1)
F4BM High Frequency PCB
brief introduction
Wangling’s F4BM high frequency materials are PTFE glass fiber cloth copper clad laminates that combine glass fiber cloth, PTFE resin, and PTFE film through a meticulous manufacturing process.
These series laminates offer improved electrical performance compared to F4B due to their wider range of dielectric constants, low dielectric loss, increased insulation resistance, and enhanced stability. Consequently, they can serve as replacements for similar foreign products.
F4BM is cladded with forward-rotating ED copper foil, making it suitable for applications without PIM (Passive Intermodulation) concerns.
Features
You have the flexibility to choose from a range of DK (dielectric constant) options spanning from 2.17 to 3.0.
The DF (dissipation factor) falls within the range of 0.001 to 0.0018.
There is a wide selection of thickness options to accommodate your specific requirements and the availability of diverse sizes allows for cost savings.
All these characteristics make it well-suited for commercial applications, large-scale production, and cost-effectiveness.
