Rogers TC350 laminates are composite substrates of PTFE, highly thermally conductive ceramic fillers and woven glass reinforcement, offering outstanding thermal conductivity to enhance heat transfer, thereby reducing dielectric and insertion loss, which results in higher gains and efficiencies in amplifiers and antennas. Its increased thermal conductivity handles higher power, reduces hot-spots, and boosts device reliability.

TC350 laminates are effective in designs with limited thermal management, improving heat transfer through the laminate, lowering junction temperatures, and extending the lifespan of active components. Its lower operating temperatures and matching thermal expansion characteristics with chips enhance component attachment reliability, reducing issues like solder fatigue and joint failure.

Features and Benefits

The TC350 laminate has a Dk of 3.5, ensuring precise impedance control and efficient signal transmission in high-frequency applications.

It exhibits excellent thermal conductivity of 0.72W/m-K, allowing for effective heat dissipation through the laminates.

TC350 maintains low thermal coefficient of Dk at -9 ppm/°C (-40°C to 140°C) minimizing the impact of temperature changes on the PCB, ensuring reliable signal transmission.

It features a low loss tangent of 0.002 at 10GHz, resulting in minimal signal loss. This feature improves bandwidth utilization and increases the efficiency of amplifiers and antennas operating at high frequencies.

TC350 exhibits low coefficients of thermal expansion on X, Y, and Z axes (7, 7, and 23 ppm/°C, respectively), providing reliable plated through hole connections and excellent dimensional stability.
