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.
PCB Capability
We provide a comprehensive range of PCB manufacturing capabilities
to fulfill your specific requirements.
At first, we can accommodate both Single Sided and Double Sided
PCBs.
Then you have the option to select from different copper weights,
such as 1oz (35µm) and 2oz (70µm), to meet your conductivity needs.
A diverse selection of dielectric thicknesses are available in our
house, ranging from 0.635mm to 2.5mm.
Our manufacturing capabilities support PCB sizes up to 240mm X
240mm and various solder mask colours like Green, Black, Blue,
Yellow, Red, and more.
Additionally, we offer various surface finish options, including
Bare copper, HASL, ENIG, Immersion silver, Immersion tin, OSP, Pure
gold, and ENEPIG etc.
Shot 4: Applications
TF high-frequency PCBs are utilized in applications of microwave
and millimeter-wave domains, such as millimeter-wave radar sensors,
antennas, transceivers, modulators, multiplexers, as well as power
supply equipment and automatic control equipment.
