Why CLTE-AT™is in a League of Its Own:

This PCB leverages the commercial-grade excellence of Rogers CLTE-AT laminate, a micro-dispersed ceramic PTFE composite with woven fiberglass reinforcement. This specific formulation strikes the optimal balance between premium performance and cost-effectiveness for high-volume, demanding applications. With a stable dielectric constant (Dk) of 3.00±0.04 and an ultra-low loss tangent (Df) of 0.0013, it ensures minimal signal attenuation and superior insertion loss (S21) figures, second only to its premium sibling, CLTE-XT™.

The CLTE-AT material's woven glass construction provides unparalleled dimensional stability, which is absolutely critical for maintaining registration in multilayer designs and for the fine 4/6 mil trace/space geometry on this board. Its extremely low coefficient of thermal expansion (CTE: 8, 8, 20 ppm/°C in X, Y, Z) guarantees electrical phase stability and mechanical reliability over a wide operating temperature range (-55°C to 150°C). Furthermore, its high thermal conductivity (0.64 W/m/K) and inherent flame retardancy (UL 94-V0) make it a robust and reliable choice for power-handling and automotive environments.

Key Features & Direct Benefits for Your Design:

• Superior High-Fidelity Signal Integrity: Ultra-low loss tangent and stable Dk ensure minimal signal distortion and phase shift, crucial for radar and microwave frequencies.
• Exceptional Mechanical & Thermal Stability: The low, balanced CTE and high thermal conductivity prevent delamination, warping, and via cracking under thermal stress, ensuring long-term reliability.
• Robust and Process-Friendly: Features excellent peel strength without requiring lossy, rough copper foils. It has low moisture absorption (0.03%) and is compatible with standard PCB processing techniques.
