TLX-8 2-Layer 10mil Thin PCB with ENIG Finish for High-Frequency Applications
1.Introduction to TLX-8 High-Volume Antenna Material
TLX-8 is a PTFE fiberglass laminate designed for high-performance RF applications. This versatile material is widely used in low-layer-count microwave designs due to its exceptional mechanical and thermal properties. It is engineered to withstand severe environments, making it ideal for:
Space launch applications: Resists creep and vibration in bolted PWBs.
High-temperature engine modules: Maintains stability under extreme heat.
Spacecraft: Offers radiation resistance and low outgassing (NASA-approved).
Military antennas: Endures harsh maritime conditions.
Aviation altimeters: Performs reliably across wide temperature ranges.
2.Key Features
Benefits of TLX-8 PCB
Superior RF Performance: PIM values below -160 dBc.
Excellent Thermal & Mechanical Stability: Low CTE and high dimensional stability.
Low Loss: Stable dielectric constant (Dk) and low dissipation factor (DF).
Robust Construction: UL 94 V0 flammability rating and low moisture absorption.
Ideal for Microwave Designs: Perfect for radar, mobile communications, and amplifiers.
Electrical & Physical Properties
Dielectric Constant (Dk): 2.55 ± 0.04 @ 10 GHz.
Dissipation Factor (DF): 0.0018 @ 10 GHz.
High Resistivity: Excellent surface and volume resistivity under humidity and elevated temps.
Thermal Stability: CTE (X/Y/Z) of 21/23/215 ppm/°C.
High Decomposition Temp: 535°C (2% weight loss), 553°C (5% weight loss).
