F4BME-2-A Teflon PCB Glass Fabric Copper-Clad Laminates
F4BME-2-A Teflon PCB glass fabric copper-clad laminates are manufactured using imported woven glass fabric, Teflon PCB resin, and filler with a Nano-ceramic membrane. This product adheres to scientific formulations and stringent technological processes, utilizing low roughness copper foil. It surpasses the F4BM series in electrical performance and surface insulation resistance stability, boasting a higher intermodulation index than F4BME-1/2.

Mechanical Strength:
- Cutting/Punching:
- Thickness <1mm: No burrs after cutting; minimum space between two punching holes is 0.55mm, no delamination.
- Thickness >1mm: No burrs after cutting; minimum space between two punching holes is 1.10mm, no delamination.
- Peel Strength (1oz copper):
- Normal state: ≥14N/cm; No bubble or delamination peel strength: ≥12N/cm (under constant humidity and temperature, kept in melting solder at 265°C ±2°C for 20 seconds).
Chemical Property: The chemical etching method for PCB can be used without altering the dielectric properties of the laminate. Plating through holes requires sodium treatment or plasma treatment.
