Product Features

Finer Nodulation

In response to the trend of thinner electronic products and higher circuit board density, our fine nodulation surface treatment and ultra-small copper nodule size facilitate the fabrication of precise etched circuits for downstream applications.

Ultimate Low Profile and High Adhesion

With ultra-low surface roughness and reduced impedance, signal loss is minimized, allowing faster signal transmission—ideal for high-end, high-frequency applications.
Our specialized surface treatment maintains high peel strength even under ultra-low roughness conditions.

Great Thermal Resistance

Excellent resistance to high temperatures and superior ductility help preserve circuit integrity and improve production yield.

Environment Friendly Issues

All products are SGS-tested and comply with RoHS, REACH, arsenic-free, halogen-free, and other international environmental standards.
