Unveiling the F4BTMS Series: Ushering in a New Era of High Frequency PCB Excellence

Presenting the highly anticipated F4BTMS series, a quantum leap forward from its predecessor, the F4BTM series. This cutting-edge collection of high frequency printed circuit boards (PCBs) encompasses groundbreaking advancements in material formulation and manufacturing techniques, setting unprecedented benchmarks in terms of material performance and dielectric constants. With a fortified composition comprising an optimal blend of ceramics and ultra-thin, ultra-fine glass fiber cloth reinforcement, the F4BTMS series emerges as a paragon of reliability, poised to supplant similar foreign offerings across the aerospace sector.

Through the seamless integration of ultra-thin glass fiber cloth and the strategic dispersion of nano-ceramics within a polytetrafluoroethylene resin matrix, the F4BTMS series adeptly mitigates the deleterious effects of glass fiber on electromagnetic wave propagation. The result is a remarkable reduction in dielectric loss, augmented dimensional stability, and a notable decrease in X/Y/Z anisotropy. Moreover, this innovative material formulation expands the usable frequency range, fortifies electrical strength, and enhances thermal conductivity, while simultaneously exhibiting exceptional low thermal expansion coefficients and steadfast dielectric temperature characteristics.

At the heart of the F4BTMS series lies the inclusion of RTF (Reduced Transmission Force) low roughness copper foil as a standard feature. This critical addition ensures significant reduction in conductor loss and endows the PCBs with exceptional peel strength. Furthermore, the series offers unparalleled versatility and ease of integration due to its compatibility with both copper and aluminum bases, accommodating a wide range of design requirements.
