Company news

Electrolytic copper foil specially developed and manufactured for the FPC industry (FCCL)

Time：2022-10-24Number：1337

Product specifications:

Advanced Institute Technology Company can provide nominal thickness of 9-35 µ m with different widthsFPC specific copper foil.

The surface of the product is gray black or red, with low surface roughness.

Suitable for flexible copper-clad laminate (FCCL), fine circuit FPC, and LED cladding film.

The material itself has high density, high bending resistance, and good etching performance.
