Introduction to F4BM High Frequency PCBs
Wangling's F4BM high frequency PCB materials are premium PTFE glass fiber cloth copper clad laminates, meticulously crafted by combining glass fiber cloth, PTFE resin, and PTFE film. These advanced laminates deliver superior electrical performance compared to standard F4B materials, making them ideal for high-frequency applications.
Key Advantages of F4BM PCBs:
Wider range of dielectric constants (DK): 2.17 to 3.0
Ultra-low dielectric loss (DF): 0.001 to 0.0018
Enhanced insulation resistance and stability
PIM-free performance with forward-rotating ED copper foil
Cost-effective replacement for imported high-frequency PCB materials
