4. TLY-3 Material: Overview & Key Features
Taconic TLY-3 is a woven fiberglass-reinforced PTFE laminate engineered to address the most demanding high-frequency and high-reliability requirements. Unlike chopped fiber PTFE composites, its woven matrix delivers superior dimensional stability—making it ideal for high-volume manufacturing (where consistency reduces waste and boosts yields).
A key advantage of TLY-3 is its performance at millimeter-wave frequencies: OEM testing at 77 GHz (critical for automotive radar) shows it matches the insertion loss and dielectric properties of competing chopped fiber materials, while delivering higher manufacturing yields (a major cost-saving benefit).
Below are TLY-3’s critical technical features (measured at 10 GHz unless noted):
| Feature | Specification |
| Dielectric Constant (Dk) | 2.33 ± 0.02 (uniform and consistent) |
| Dissipation Factor (Df) | 0.0012 (ultra-low for minimal signal loss) |
| Thermal Conductivity | 0.22 W/mK (unclad, efficient heat transfer) |
| CTE (x/y/z) | 26 ppm/°C / 15 ppm/°C / 217 ppm/°C |
| Peel Strength (1oz Cu) | 17 lbs/in (strong bond between copper and substrate) |
| Moisture Absorption | 0.02% (near-zero, preventing performance degradation from humidity) |
| Flammability Rating | UL 94 V-0 (flame-retardant, safe for automotive/aerospace use) |
| Outgassing (TML/CVCM/WVR) | 0.01% / 0.01% / 0.01% (meets strict aerospace outgassing requirements) |
| Laser Ablatability | Yes (enables precise, high-resolution fabrication for complex designs) |
5. Core Benefits of the TLY-3 PCB
This PCB leverages TLY-3’s inherent advantages to solve key challenges in high-frequency and high-reliability applications:
Superior Dimensional Stability: Woven fiberglass matrix eliminates warpage or shrinkage during manufacturing, boosting yields and ensuring consistent fit in assemblies.
Ultra-Low Dissipation Factor (0.0012): Minimizes signal loss at high frequencies (e.g., 77 GHz automotive radar, Ka-band satellite communications), preserving data integrity.
Consistent Dielectric Constant (±0.02): Ensures predictable signal behavior across the PCB, critical for precision components like filters and couplers.
High Peel Strength (17 lbs/in for 1oz Cu): Reinforces the bond between copper layers and the TLY-3 core, preventing delamination under thermal stress (e.g., automotive temperature cycles).
Near-Zero Moisture Absorption (0.02%): Protects performance in humid environments (e.g., aerospace or outdoor telecommunications), avoiding dielectric breakdown or signal degradation.
Laser Ablatability: Enables high-precision fabrication of fine features, supporting miniaturized designs for space-constrained applications.
6. Typical Applications
Automotive Radar: Optimized for 77 GHz systems (adaptive cruise control, collision avoidance), with low signal loss and dimensional stability to withstand automotive temperature cycles.
Satellite/Cellular Communications: Performs reliably in Ka, E, and W band frequencies, supporting high-speed data transfer for satellite links and 5G/6G infrastructure.
Aerospace & Avionics: Meets strict outgassing and flame-retardant standards (UL 94 V-0), suitable for in-cabin electronics and radar systems.
High-Frequency Amplifiers & Receivers: Ideal for Low-Noise Amplifiers (LNAs), Low-Noise Blocks (LNBs), and Low-Noise Converters (LNCs), where low Df preserves signal quality.
Precision Passive Components: Supports filters, couplers, and phase shifters, thanks to TLY-3’s consistent Dk and low moisture absorption.
Conclusion
This 2-layer PCB with Taconic TLY-3 material represents a perfect blend of precision, performance, and reliability. Its tight manufacturing tolerances (e.g., ±0.15mm dimensions, 4/6 mil trace/space), industry-standard quality (IPC-Class-2), and TLY-3’s ultra-low Df and dimensional stability make it a trusted solution for high-frequency and high-reliability applications.
