F4BTM High Frequency Laminates
The F4BTM series of high-frequency materials are composed of glass fiber cloth, nano-ceramic fillers, and polytetrafluoroethylene resin, developed through rigorous preparation and precise pressing processes.
This series of products builds upon the F4BM dielectric layer, added with high-dielectric, low-loss nanoscale ceramics, resulting in superior dielectric constants, improved heat resistance, lower thermal expansion coefficients, higher insulation resistance, and enhanced thermal conductivity—all while preserving low loss characteristics.
