How does F4BM220 PCB compare to F4BME220?
F4BM220 PCB and F4BME220 PCB are two variants of laminates with slight differences in their copper foil combinations. Here's a comparison between the two:
- Dielectric Layer:F4BM220 and F4BME220 share the same dielectric layer material, which consists of a combination of fiberglass cloth and polytetrafluoroethylene (PTFE) resin.
- Copper Foil Combination: The main difference lies in the copper foil used in each laminate. F4BM220 is paired with ED (Electro-Deposited) copper foil, whereas F4BME220 is paired with reverse-treated foil (RTF) copper foil.
- PIM Performance:F4BM220, with its ED copper foil, is suitable for applications without PIM (Passive Intermodulation) requirements. On the other hand, F4BME220, with RTF copper foil, offers excellent PIM performance. This makes F4BME220 a preferable choice when precise line control, lower conductor loss, and superior PIM performance are needed.
- Electrical Performance:While both laminates offer improved electrical performance compared to F4B220, F4BM220 exhibits lower dielectric loss, increased insulation resistance, and improved stability. The precise control of the dielectric constant achieved by adjusting the ratio between PTFE and fiberglass cloth in F4BM220 leads to lower loss and enhanced dimensional stability.
In summary, F4BM220 and F4BME220 share the same dielectric layer, but F4BM220 is paired with ED copper foil for applications without PIM requirements, whereas F4BME220 is paired with RTF copper foil to provide excellent PIM performance, precise line control, and lower conductor loss. The choice between the two depends on the specific requirements of the application hand.
