F4BTM High Frequency PCB

Introduction

Wangling’s F4BTM series laminates are fiberglass cloth, nano-ceramic fillers, and PTFE resin, followed by strict pressing processes. They are based on the F4BM dielectric layer, with the addition of high dielectric and low loss nano-level ceramics, resulting in higher dielectric constant, improved heat resistance, lower thermal expansion coefficient, higher insulation resistance, and better thermal conductivity, while maintaining low loss characteristics.

F4BTM and F4BTME share the same dielectric layer but use different copper foils: F4BTM is paired with ED copper foil, while F4BTME is paired with reverse-treated (RTF) copper foil, offering excellent PIM performance, more precise line control, and lower conductor loss.

Features

F4BTM offers a wide range of features. With a DK range from 2.98 to 3.5, it provides flexibility in design. The addition of ceramics further enhances its performance, making it suitable for demanding applications. This material is available in various thicknesses and sizes, catering to different project requirements while offering cost savings. Its commercialization and suitability for large-scale production make it a highly cost-effective choice. Additionally, F4BTM exhibits radiation-resistant and low out-gassing properties, ensuring its reliability even in challenging environments.
