Taconic TLX-9 RF PCB materials Introduction Welcome back to our channel.. Today, we're going to discuss the TLX-9 high frequency laminate, a form of woven glass reinforced PTFE PCB material. Taconic TLX-9 high frequency PCB material uses combinations of 1080 or 106 style fiberglass and exhibits excellent dimensional and electrical performance. In addition, TLX-9 laminate are available in a wide range of thicknesses, making them ideal for double-sided or multilayer applications. Let’s see the data sheet in details. TLX-9 Typical Properties Taconic TLX-9 PCB substrate possesses a low dielectric constant of 2.5 at 10 GHz, as well as a low dissipation factor of 0.0019 at the same frequency. These characteristics make it an excellent choice for high-frequency applications where signal integrity is paramount. In addition to its impressive electrical properties, TLX-9 also has a moisture absorption rate of less than 0.02%, ensuring stability and reliability in damp environments. It also has a dielectric breakdown voltage of over 60 kV, making it suitable for use in high-voltage applications. Taconic TLX-9's volume resistivity and surface resistivity both exceed 10^7 Mohm/cm, ensuring excellent electrical insulation properties. Its arc resistance is also over 180 seconds, indicating exceptional resistance to electrical arcing. When it comes to mechanical strength, TLX-9 does not disappoint. It has a flexural strength of over 23,000 lbs./in. lengthwise and over 19,000 lbs./in. crosswise, making it a highly durable material. It also has a peel strength of 12 lbs./linear in. for 1 oz. copper. However, TLX-9's thermal conductivity is only 0.19 W/m/K. It has a CTE of 9 ppm/°C in X-direction and 12 ppm/°C in Y-direction, while 130-145 ppm/°C in Z-direction. Finally, TLX-9 has a UL-94 flammability rating of V-0, indicating that it is highly resistant to ignition and will self-extinguish quickly if it does catch fire.

This outgassing test result shows that total mass loss (TML) of TLX-9 is 0.02%. Collected volatile condensable materials (CVCM) is 0.01%, while the amount of water vapor regained (WVR) is zero. As a result of these extremely low levels, the results far exceed the normal needed value.

We can also find its usage in radar systems, mobile communications, microwave test equipment, and microwave transmission devices etc. Conclusion The TLX product lines are the workhorse in the RF microwave substrates industry because the fiberglass provides mechanical support whenever the substrates encounter harsh environments, such as resistance to creep for PCBs fastened to housings that experience high vibration levels during space launch; exposure to high temperatures for engine modules; radiation protection in space; resistance to harsh marine environments for warship antennas; and resistance to a broad temperature range while in flight and so on. Taconic TLX-9 High-Frequency Laminate is a woven glass-reinforced PTFE substrate engineered for high-performance RF and microwave applications. With a low dielectric constant of 2.5 and a dissipation factor of 0.0019 at 10 GHz, it delivers exceptional signal integrity and stability. Featuring high dielectric strength (>60 kV), low moisture absorption (<0.02%), and strong mechanical properties, TLX-9 is ideal for multilayer PCBs, RF modules, and demanding communication or radar systems where reliability is critical. Well, This concludes the episode. Thank you for reading. We’ll see you next time.
