F4BTM350 Material Introduction

Wangling's F4BTM350 laminates are manufactured through scientific formulation of fiberglass cloth, nano-ceramic filling, and polytetrafluoroethylene resin, followed by strict pressing processes. Based on the F4BM dielectric layer, this material incorporates high-dielectric, low-loss nano-ceramics, which significantly enhance its dielectric constant, heat resistance, insulation resistance, and thermal conductivity, while reducing the thermal expansion coefficient and retaining low-loss characteristics.

F4BTM350 and F4BTME350 share the same dielectric layer but differ in copper foil matching: F4BTM350 is paired with ED copper foil, suitable for applications without PIM requirements; F4BTME350 uses reverse-treated (RTF) copper foil, providing excellent PIM performance, more precise line control, and lower conductor loss.
