Introduction
Wangling’s TFA300 high frequency material utilizes a large amount of uniform special nano-ceramics mixed with PTFE resin, eliminating the fiberglass effect during the propagation of electromagnetic waves.
A new manufacturing process is employed to create prefabricated sheets, which are pressed using a special lamination process. This material exhibits outstanding electrical, thermal, and mechanical properties with excellent dielectric constant at the same level, making it an aerospace-grade high-frequency and high-reliability material that can replace similar foreign products.
Features
TFA300 features a low dielectric constant of 3 at 10GHz, enabling minimal signal delay and optimal impedance control for high-speed/high-frequency applications (e.g., 5G, radar, mmWave circuits).
Ultra-low dissipation factor of 0.001 at the same frequency ensures minimal signal loss and high-quality signal integrity in RF/microwave PCBs and antennas.
It also features a great TCDk value of -8 PPM/℃,providing exceptional dielectric constant stability across a wide temperature range (-40°C to +150°C), critical for automotive, aerospace, and outdoor telecom systems.
The peel strength is greater than 1.6N/mm, indicating superior adhesion between copper layers and substrate, reducing delamination risks in multilayer PCBs.
18 PPM/ºC of X/Y axis CTE, closely matching copper’s CTE of 17 ppm/°C, minimizes the stress-induced warpage during thermal cycling. 30 ppm/°C of Z axis, balances rigidity and flexibility for reliable plated through-hole (PTH) integrity.
TFA300 also shows low water absorption of 0.04%, a higher thermal conductivity of 0.8W/MK.
Finally, it meets the flammability standard of UL-94 V-0.
