Introduction to F4BTME-1/2
F4BTME-1/2 is a laminated material created by combining imported varnished glass cloth with Teflon PCB resin and filler, incorporating a Nano-ceramic membrane. This product adheres to strict scientific formulations and technology processes. It employs low roughness copper foil, offering superior electrical performance compared to the F4BM-2-A series, enhanced heat dissipation, and a smaller thermal expansion coefficient. It is stable in PIM and suitable for 4G and 5G communications.
