Product Description
TF960 High-DK Ceramic-Filled PTFE Laminate & Custom 2-Layer PCB Solution
1. Introduction to TF960 High-Frequency Laminate
TF960 is a high-performance ceramic-filled PTFE composite laminate manufactured by Taizhou Wangling Insulation Material Factory. Unlike traditional PTFE fiberglass laminates, TF960 is composed of microwave-grade PTFE resin combined with ceramic fillers, without any fiberglass cloth reinforcement. This unique composition allows for precise dielectric constant adjustment by varying the ceramic-to-PTFE ratio, resulting in exceptional electrical performance and high reliability.
TF960 specifically features a dielectric constant of 9.6 ± 0.19 at 10 GHz, making it an ideal choice for high-frequency impedance matching, miniaturization, and phase-sensitive applications. The material contains no fiberglass reinforcement, which eliminates glass-fiber-induced anisotropy and provides superior electrical performance compared to woven-reinforced PTFE materials.
The material supports lead-free assembly (compatible with 260°C reflow processes) and offers excellent thermal stability, moisture resistance, and low outgassing, making it suitable for aerospace, defense, and high-reliability commercial applications.

TF960 delivers a comprehensive set of advantages for high-frequency and high-reliability applications:
| Feature | Description |
| High Dielectric Constant (9.6) | Enables circuit miniaturization and reduced wavelength |
| Tight Dk Tolerance (±0.19 / ±2%) | Excellent batch-to-batch consistency |
| Ultra-Low Dissipation Factor | 0.0012 @ 10 GHz – minimizes insertion loss |
| No Glass Fiber Reinforcement | Eliminates anisotropy and reduces dielectric loss |
| Wide Operating Temperature Range | -80°C to +200°C – exceeds standard PTFE materials |
| Radiation Resistance & Low Outgassing | Suitable for space and aerospace applications |
| UL 94 V-0 Flammability | Meets stringent safety requirements |
| Lead-Free Assembly Compatible | Supports 260°C reflow processes |
Superior Electrical Performance: The absence of fiberglass cloth eliminates the "glass-fiber effect" that can cause variations in dielectric constant and increased loss at high frequencies. The ceramic-filled PTFE composition provides stable, isotropic electrical properties.
Circuit Miniaturization: The high Dk of 9.6 allows for significant reduction in circuit size compared to low-Dk materials, enabling compact RF and microwave designs.
Excellent Temperature Stability: With a TCDk of -260 ppm/°C, TF960 maintains stable electrical performance across a wide temperature range.
Low Moisture Absorption (≤0.05%): Ensures consistent dielectric properties in humid environments.
Enhanced Thermal Management: Thermal conductivity of 0.68 W/(m·K) supports efficient heat dissipation in power applications.
Easy Processing: Can be processed using standard thermoplastic PCB manufacturing techniques – no specialized processing required.
High Reliability: Excellent dimensional stability with low CTE (50/50/65 ppm/°C) ensures reliable plated-through-hole integrity.
