Taconic TLY-5 high-frequency circuit boards, renowned for exceptional dielectric stability, have become the core substrate for 5G millimeter-wave and satellite communications. When enhanced with ENIG surface treatment, their high-frequency characteristics and reliability are significantly improved. Below are the key features professional high-frequency RF PCB manufacturers must master about ENIG TLY-5 boards:
Five Core Advantages of ENIG TLY-5 HF Boards
Ultra-Stable Dielectric Properties
TLY-5 substrate offers an ultra-low dielectric constant of 2.20±0.02 (@10GHz) with less than 0.25% variation across -55℃ to +150℃. ENIG processing improves high-frequency RF PCB phase consistency by 35%, meeting stringent requirements for millimeter-wave phased array antennas.
Extremely Low-Loss Transmission
With a dissipation factor of 0.0019 (@10GHz) optimized by ENIG, 60GHz millimeter-wave transmission efficiency increases by 20%. Professional high-frequency PCB factories using this process can reduce base station antenna insertion loss by 15%.
Excellent Thermo-Mechanical Performance
Z-axis CTE as low as 17ppm/℃ perfectly matches copper foil. The ENIG layer withstands 6×260℃ lead-free reflows, solving thermal stress issues in multilayer HF boards.
Outstanding Environmental Resistance
Passing 120-hour 85℃/85%RH testing, ENIG’s corrosion resistance outperforms conventional processes by 5×. The nickel-gold barrier ensures reliable performance for automotive radars in harsh conditions.
High-Density Interconnect Assurance
ENIG delivers:
- Pad flatness <5μm
- Solderability window >15 hours
- Void rate <3% (better than IPC Class 3)
