Wangling TP High Frequency PCBs A Unique Thermoplastic Solution for Demanding Applications

October 9, 2025

In the world of high-frequency materials, true innovation is rare. Wangling’s TP series breaks the mold as a unique thermoplastic laminate that combines ceramic and Polyphenylene Oxide (PPO) resin—without traditional fiberglass reinforcement. This distinctive composition allows for unprecedented control over dielectric properties, making TP materials a top choice for specialized, high-reliability applications.

What Makes TP Material Unique?

TP stands out as a high-frequency thermoplastic where the dielectric layer is composed solely of ceramics and PPO resin. This fiberglass-free construction offers several key advantages:
Tunable Dielectric Constant: Dk can be precisely adjusted between 3 and 25 by modifying the ceramic-to-resin ratio
Excellent Dielectric Performance: Low loss and stable electrical properties across a broad frequency range
High Reliability: Superior copper adhesion compared to vacuum-coated ceramic substrates
Robust Environmental Performance: Radiation-resistant and low outgassing, suitable for harsh environments

Key Material Properties

Wide Dk Range: Common values include 3.0, 4.4, 6.0, 6.15, 9.2, 9.6, 10.2, 11, 16, and 20
Low Dielectric Loss: Minimal increase within the 10 GHz range
Broad Temperature Range: Operates from -100°C to +150°C with excellent low-temperature performance
Thermal Limitations: Avoid sustained temperatures above 180°C to prevent deformation and performance degradation

Common Applications

TP high-frequency PCBs are ideal for demanding applications where performance and reliability are critical:

Beidou navigation systems
Missile-borne electronics
Weapon fuzes
Miniaturized antennas
Aerospace and defense systems
High-reliability communications

Why Choose TP Material?

For engineers designing systems that require specific dielectric constants, extreme environmental stability, or miniaturization, TP material offers unique advantages. The ability to precisely tune the Dk between 3 and 25—without fiberglass-related limitations—provides design flexibility unavailable in conventional materials.

While the maximum board size is limited compared to some materials, TP's exceptional electrical performance, temperature resilience, and radiation resistance make it indispensable for specialized military, aerospace, and high-frequency applications.
