Ultra Low Profile (VLP)

1、Ultra low roughness.

2、Superior chemical resistance good etching factor.

3、Good high-temperature elongation.

PTFE resin, hydrocarbon resin, PPO or PPE, high-frequency high-speed materials

5G high-speed signal transmission product, which can meet the requirements of medium loss, low loss The dem for ultra-low loss circuit boards.
