About TP960 Laminate

The TP960 laminate is a high-frequency thermoplastic material combining ceramics and polyphenylene oxide (PPO) resin. Its unique composition eliminates fiberglass reinforcement, reducing negative impacts on electromagnetic wave propagation while maintaining dimensional stability and low dielectric loss. This material is ideal for miniaturized, high-frequency applications requiring exceptional reliability.

Key Features of TP960:

• Dielectric Constant (Dk): 9.6 ± 0.19 at 10GHz, providing precise impedance control.
• Dissipation Factor (Df): 0.0012 at 10GHz, ensuring minimal signal loss.
• CTE (Coefficient of Thermal Expansion): X-axis: 40 ppm/°C, Y-axis: 40 ppm/°C, Z-axis: 55 ppm/°C
• Thermal Coefficient of Dk: -40 ppm/°C, ensuring stable performance across -55°C to 150°C.
• Thermal Conductivity: 0.65 W/mK, enabling efficient heat dissipation.
• Moisture Absorption: 0.01%, ensuring stability in humid environments.
• Flammability: UL 94-V0, meeting safety standards.

TP960 laminates allow for dielectric constants ranging from 3 to 25, tailored to circuit requirements, and maintain stability across a wide frequency range.

Benefits of TP960-Based PCBs

The low dissipation factor (Df) and stable dielectric constant (Dk) ensure minimal signal distortion and high-frequency reliability.

With low TCDk (-40 ppm/°C) and high thermal conductivity (0.65 W/mK), the PCB provides consistent performance even in extreme temperature environments.

The material's low moisture absorption (0.01%) ensures dimensional stability, even in humid or harsh environments.

The ENIG surface finish enhances solderability, corrosion resistance, and wire-bonding compatibility, making it suitable for critical applications.

The ability to select dielectric constants between 3 and 25 makes TP960 versatile for a wide range of high-frequency applications.

TP960 laminates' dimensional stability and smooth surface simplify fabrication while ensuring consistent results.
