F4BTM300 PCB 2-layer, 40 mil thick, immersion gold, suitable for radar, microwave, and RF applications

Introduction of F4BTM300:
Wangling's F4BTM300 laminates are meticulously crafted by blending fiberglass cloth, nano-ceramic filling, and polytetrafluoroethylene resin through precise pressing processes. Leveraging the F4BM dielectric layer as a foundation,

the F4BTM300 series integrates high dielectric and low loss nano-level ceramics, enhancing the dielectric constant, heat resistance, thermal expansion coefficient, insulation resistance, and thermal conductivity while preserving low loss attributes.

F4BTM300 and F4BTME300 share a common dielectric layer but differ in copper foils: F4BTM employs ED copper foil,

suitable for applications not requiring PIM compliance, while F4BTME is paired with reverse-treated (RTF) copper foil,

ensuring superior PIM performance, precise line control, and reduced conductor loss.
