2) Superior mechanical and thermal stability, withstanding extreme temperature fluctuations and physical stress

3) Low and stable dielectric constant (Dk = 2.55±0.04 at 10GHz) for consistent signal propagation

4) Tight dimensional stability (≤0.10 mm/M after thermal stress) to maintain precision in assembled systems

5) Ultra-low moisture absorption (0.02%), preventing performance degradation in humid environments

6) Low dissipation factor (DF = 0.0018 at 10GHz) for minimal signal loss in high-frequency applications

7) UL 94 V0 flammability rating, enhancing safety in critical systems

Main Technical Properties

The TLX-8 PTFE Laminate PCB’s performance is validated by rigorous testing to IPC-650 and ASTM standards:

1) Electrical Performance: Surface resistivity (6.605 x 10⁸Mohm at elevated temperatures) and volume resistivity (1.110 x 10¹⁰Mohm/cm) ensure reliable insulation, while dielectric breakdown (> 45 Kv) guarantees robustness.

2) Thermal Stability: Decomposition temperature (Td) of 535°C (2% weight loss) and 553°C (5% weight loss) enables operation in high-heat environments.

3) Dimensional & Mechanical Integrity: Coefficient of thermal expansion (CTE) of 21-23 ppm/°C (X/Y axes) minimizes warpage, while excellent chemical resistance ensures longevity in harsh atmospheres.
