Key PCB Specifications

PCB Capability (TLX-8)

Material Overview: Taconic TLX-8

The TLX-8 laminate is a PTFE-based microwave substrate reinforced with fiberglass for enhanced mechanical stability. It offers a low and stable dielectric constant (Dk=2.55±0.04D_k = 2.55 ± 0.04Dk​=2.55±0.04) and a low dissipation factor (DF=0.0018DF = 0.0018DF=0.0018), making it ideal for high-frequency operations with minimal signal loss. The material’s dimensional stability and resistance to moisture absorption further enhance its reliability in harsh environmental conditions.

Key Features of TLX-8:

• Dielectric Constant (Dk): 2.55 ± 0.04 at 10GHz for consistent electrical performance.
• Dissipation Factor (DF): 0.0018 at 10GHz, ensuring low signal loss.
• Thermal Coefficient of Dielectric Constant: -70 ppm/°K for stable performance over temperature variations.
• Thermal Conductivity: 0.19 W/m*K, providing reliable thermal management.
• Moisture Absorption: 0.02%, ensuring durability in humid environments.
• Flammability Rating: UL 94 V-0 for safe operation in demanding applications.

Benefits of TLX-8 PCB

High-Frequency Performance: The low dissipation factor and stable dielectric constant ensure excellent electrical performance, making this PCB suitable for microwave and RF designs where signal integrity is critical.

Exceptional Durability: The fiberglass reinforcement provides dimensional stability and resistance to mechanical stress, allowing the PCB to perform reliably in harsh environments, such as high-vibration conditions or extreme temperatures.

Thermal Stability: With a CTE (Coefficient of Thermal Expansion) closely matched to copper and a Thermal Decomposition Temperature (Td) of 535°C, the PCB is highly resistant to thermal stress and delamination.

Moisture Resistance: The low moisture absorption rate (0.02%) ensures consistent performance in humid or marine environments, such as warship antennas or offshore communication equipment.

Ease of Fabrication: The TLX-8 laminate supports standard fabrication processes, making it a cost-effective choice for low-layer microwave designs without compromising on performance.

Applications

The TLX-8 PCB is engineered for a wide range of RF and microwave applications, including:

Antennas: Ideal for radar systems, satellite communications, and warship antennas.
