Taconic TLY-5 2-Layer 125mil Thick PCB with Immersion Gold Finish for RF Applications
1.Introduction to Taconic TLY-5 High-Frequency PCB Material
Taconic TLY-5 laminates utilize precision-woven fiberglass for superior dimensional stability, outperforming standard chopped fiber PTFE composites. Engineered for high-volume manufacturing, this material delivers ultra-low signal loss, making it ideal for:
77GHz automotive radar (ADAS/autonomous driving)
Millimeter-wave antennas (5G, satellite, defense)
Mission-critical aerospace & telecom systems
2.Key Features of Taconic TLY-5 PCB
Superior Electrical Performance
Dielectric Constant (Dk): 2.2 ± 0.02 @ 10GHz (industry-leading consistency)
Loss Tangent (Df): 0.0009 @ 10GHz (minimizes RF signal loss)
Moisture Absorption: 0.02% (ensures reliability in harsh environments)
Mechanical Reliability
CTE: X/Y/Z = 26/15/217 ppm/°C (prevents warping in thermal cycles)
Density: 2.19 g/cm³ (lightweight yet robust)
Copper Peel Strength: High adhesion for durable interconnects
Benefits Summary
Best-in-class dimensional stability
Lowest loss tangent for mmWave/77GHz designs
NASA-grade moisture resistanc
Proven in automotive, aerospace & 5G infrastructure
