Taconic TLY-5 High Frequency PCB Material Introduction TLY laminates, developed by Taconic Company, utilize an advanced lightweight woven fiberglass reinforcement structure that delivers superior dimensional stability compared to traditional chopped fiber-reinforced PTFE composites. This enhanced mechanical consistency makes TLY materials particularly suitable for high-volume manufacturing environments where process reliability and yield are critical. With an optimized low dissipation factor, TLY laminates support high-frequency performance up to and beyond 77 GHz, positioning them as an ideal substrate for advanced automotive radar systems, 5G millimeter-wave antennas, and next-generation wireless communication devices. Among the series, TLY-5 high frequency material stand out as a high-performance grade offering excellent electrical stability, consistent dielectric properties, and reliable thermal performance. Whether used in automotive radar modules, satellite communications, or high-frequency aerospace applications, TLY-5 PCB substrate ensures consistent signal integrity and manufacturing repeatability in demanding environments. TLY laminates combine the benefits of mechanical robustness, millimeter-wave capability, and manufacturability—making them a trusted choice for engineers designing high-frequency systems that require precision, scalability, and long-term reliability. We benefit from its following advantages: 1. Dimensionally stable: High volume fabrication becomes possible. 2. Lowest DF In the low dielectric constant range, the dissipation factor is approximately 0.0009 at 10 GHz. 3. Low moisture absorption It can work in severe environment. 4. High copper peel strength It’s high up to 2.32, dimensionally stable. 5. Uniform and consistent DK For most thicknesses, the dielectric constant can be specified anywhere within this range with a tolerance of +/-0.02 Typical applications include: Automotive radar Cellular communications Satellite communications Power amplifiers, Filters, couplers LNBs, LNAs, LNCs Aerospace, avionics Phased array antennas Conclusion Taconic TLY-5 laminates feature lightweight woven fiberglass reinforcement, providing excellent dimensional stability and mechanical consistency ideal for high-volume production. With a tightly controlled dielectric constant of 2.17–2.40 (±0.02) and an ultra-low dissipation factor, TLY-5 PCB material ensures reliable performance in demanding applications such as automotive radar at 77 GHz and millimeter-wave antennas. Its balanced electrical properties and manufacturing efficiency make TLY-5 a trusted choice for RF, aerospace, and communication systems. There’re 6 members in TLY family.
