F4BTM450 3.2mm High Frequency PCB

Shipped: 8th-FEB-2024

1. F4BTM Introduction
F4BTM is a series of high-frequency circuit laminates composed of glass fiber cloth, nano-ceramic filling, and polytetrafluoroethylene resin. It undergoes a scientific preparation and strict process pressing.

This product series is based on the F4BM dielectric layer and incorporates high-dielectric and low-loss nanoscale ceramics. As a result, it achieves a higher dielectric constant, improved heat resistance, reduced coefficient of thermal expansion, enhanced insulation resistance, and better thermal conductivity. These improvements are achieved while maintaining the low-loss characteristics of the material.

F4BTM is paired with forward rotating ED copper foils, making it suitable for applications where PIM (Passive Intermodulation) indicators are not a concern.
