TF High Frequency PCB

Introduction

Wangling’s TF laminates are a composite of microwave and temperature-resistant polytetrafluoroethylene (PTFE) resin material and ceramics. These laminates are free from fiberglass cloth and the dielectric constant is precisely adjusted by adjusting the ratio between ceramics and PTFE resin. With the application of special production processes, they demonstrate outstanding dielectric performance and offer a high level of reliability.

Features

TF laminates exhibit a stable and wide range of dielectric constant, which ranges from 3 to 16, with common values including 3.0, 6.0, 9.2, 9.6, 10.2, and 16.

TF laminates feature exceptionally low dissipation factor, with loss tangent values of 0.0010 for DK ranging from 3.0 to 9.5 at 10GHz, 0.0012 for DK from 9.6 to 11.0 at 10GHz, and 0.0014 for DK spanning 11.1 to 16.0 at 5GHz.

With a long-term working temperature surpassing TP materials, they can operate within a wide range of -80°C to +200°C

The laminates come in thickness options ranging from 0.635mm to 2.5mm, catering to various design requirements.

They boast resistance to radiation and exhibit low outgassing properties.
