Part 2: In-Depth Technical Breakdown of TLY-5 Core CCL Substrate
2.1 TLY-5 Material Core Introduction & Differentiation
AGC TLY-5 is an avionics and aerospace-grade woven lightweight fiberglass-reinforced PTFE copper clad laminate, engineered to outperform chopped-fiber PTFE composite substrates in dimensional stability and mass-production yield while retaining ultra-low high-frequency signal loss. Unlike discontinuous chopped fiber PTFE materials that suffer inconsistent dielectric uniformity and high thermal expansion variation, TLY-5’s continuous woven glass matrix delivers superior mechanical rigidity and predictable DK/Df across all operating frequencies from 10GHz up to 77GHz automotive radar and Ka/E/W band satellite hardware.
Independent OEM 77GHz insertion loss testing confirms TLY-5 matches the RF electrical performance of competing chopped-fiber PTFE laminates, with a dramatic uplift in production yield–a critical commercial differentiation for high-volume automotive radar manufacturing. The material supports laser ablation via formation, compatible with fine-line 6/10mil trace routing specified on the matching PCB hardware, and is available in incremental thickness steps starting at 7.5mil (0.191mm), the exact dielectric core selected for this PCB design.

2.4 Core Functional Advantages of TLY-5 CCL (Differentiated Value Points)
1)Exceptional Dimensional Stability: Woven glass fiber matrix eliminates uneven shrinkage/expansion seen in chopped PTFE, delivering consistent impedance across thousands of RF PCBs in mass production.
2)Ultra-Low Dissipation Factor (Df=0.0009 @10GHz): Industry-leading low loss tangent minimizes millimeter-wave signal attenuation, critical for long-range automotive radar and high-gain satellite antennas.
3)Near-Zero Moisture Absorption (0.02%): Resists humidity-induced Dk shift, preserving stable RF performance in harsh automotive and aerospace temperature-humidity cycling environments.
4)High Copper Peel Strength: Maintains robust copper foil adhesion under high-temperature rework and thermal cycling, reducing delamination field failures.
5)Uniform, Tightly Toleranced Dk: Customizable dielectric constant with±0.02 tolerance eliminates unpredictable impedance drift for precision mmWave filter and coupler circuits.
6)Laser Ablatable Dielectric: Compatible with laser microvia processing for fine-line dense RF layouts, matching the 6/10mil trace routing capability of the target PCB design.
7)Aerospace-Qualified Low Outgassing: NASA outgassing metrics of 0.01% TML/CVCM/WVR meet satellite and avionics vacuum environment reliability standards, with UL-94 V-0 flame retardant safety rating.
