Wangling TF300 DK 3.0, 6.0, 9.2, 9.6, 10.2 High-Frequency Laminate and Custom 25mil Subsstrate PCB ENEPIG Finish

Product Description

In the pursuit of reliable microwave and millimeter-wave performance, material selection is critical. Wangling's TF300 high-frequency laminate is a PTFE-ceramic composite dielectric substrate engineered to deliver stable dielectric constant, low loss, and excellent reliability for demanding RF applications. Unlike glass-reinforced laminates, TF300 contains no glass fiber cloth—the dielectric constant is precisely calibrated by adjusting the ratio of ceramic to PTFE resin, resulting in superior dielectric performance and consistent electrical characteristics.

The TF series is available in three configurations: TF (unclad, smooth surface), TF-1 (single-sided copper clad), and TF-2 (double-sided copper clad). TF300 is offered with ED copper foil in 0.018mm and 0.035mm thicknesses, in panel sizes of 150×150mm and 250×250mm, with standard thicknesses from 0.635mm to 2.5mm.

As a specialized manufacturer of high-frequency printed circuit boards, we offer comprehensive fabrication services using Wangling TF300 and other advanced materials. The following specification details a representative 2-layer rigid PCB implementation:

PCB Construction Details:

Precisely Controlled Dielectric Constant:

TF300 offers a dielectric constant of 3.0 ± 0.06 at 10 GHz, with the Dk precisely calibrated by adjusting the ceramic-to-PTFE ratio. The TF series covers a wide Dk range from 3 to 16, with commonly used values including 3.0, 6.0, 9.2, 9.6, 10.2, and 16—enabling engineers to select the optimal material for each application.

Low Dielectric Loss:
With a dissipation factor of just 0.001 at 10 GHz, TF300 minimizes signal attenuation in transmission lines, ensuring excellent high-frequency performance for microwave and millimeter-wave circuits.

No Glass Fiber Reinforcement:
Unlike glass-reinforced laminates, TF300 contains no glass fiber cloth. This eliminates fiber-induced variations in dielectric constant and provides more homogeneous electrical performance across the substrate.

Wide Operating Temperature Range:
TF300 can be used continuously in the range of -80°C to +200°C—a higher continuous operating temperature than TP materials—making it suitable for aerospace and defense applications subject to extreme thermal environments.

Radiation Resistance and Low Outgassing:
The material exhibits radiation resistance and low outgassing properties, critical for space and satellite applications where material degradation and contamination must be minimized.

Excellent Dimensional Stability:
The CTE values (60/60/80 ppm/°C for X/Y/Z) contribute to reliable plated through-holes and consistent circuit performance across temperature variations.

Easy PCB Fabrication:
TF300 is processable with standard manufacturing methods for thermoplastic materials, allowing all common PCB processes to be used without specialized production techniques.

Customizable Thicknesses:
Available in thicknesses from 0.635mm to 2.5mm, with both "total thickness including copper" and "dielectric thickness" options available upon request.
