Hello everyone, Today, we’ll be discussing the TLF-35 high-frequency PCB material.
Taconic’s TLF-35 is an advanced organic-ceramic laminate that utilizes woven glass reinforcement as its core structure. This material is engineered through a combination of innovative ceramic filler technology and a specialized coating of PTFE (polytetrafluoroethylene) on fiberglass. |

We gain several key advantages from using TLF-35:
1. Enhanced Phase Intermodulation Distortion (PIMD) with Dk 3.5
TLF-35 is engineered to deliver superior PIMD performance, making it ideal for compact PCB designs in antenna applications. With a dielectric constant (Dk) of 3.5, it aligns perfectly with the requirements for optimal PIMD levels.
2. Superior Plated Through-Hole (PTH) Quality
This material ensures excellent PTH quality, providing stronger hole wall stability and improved insulation resistance, even for smaller drilled holes.
3. Exceptional High-Frequency Stability
TLF-35 is specifically designed to maintain outstanding performance in high-frequency environments, ensuring reliable signal integrity and minimal loss.
4. Ultra-Low Moisture Absorption
Thanks to its extremely low moisture absorption rate and low dissipation factor, TLF-35 minimizes phase shifts across varying frequencies, ensuring consistent performance.
5. Cost-Effectiveness
TLF-35 offers a cost-efficient solution, enabling high-volume production for commercial microwave and radio frequency applications without compromising on quality. |
