F4BTM300 Material Introduction

F4BTM series laminates are produced through a precision manufacturing process, blending glass fiber cloth, nano-ceramic fillers, and polytetrafluoroethylene (PTFE) resin in a scientifically formulated mixture. Built on the F4BM dielectric layer, F4BTM300 incorporates high-Dk, low-loss nano-ceramics, yielding enhanced dielectric constant, superior heat resistance, reduced thermal expansion coefficient, elevated insulation resistance, and improved thermal conductivity—all while maintaining low-loss performance.

F4BTM300 laminates are specifically matched with reverse-treated RTF copper foil, delivering excellent PIM performance, precise line accuracy, and minimized conductor loss. These characteristics make it ideal for demanding applications that require stable performance across extreme temperature ranges and harsh operating environments.
