Rolled Copper Foil

Overview

Rolled copper foil is more flexible than electrolytic copper foil, and has stable mechanical properties under high temperature conditions. It is an optimal material for high density mounting of electronic devices. Using our excellent metal rolling technology, we provide rolled copper foils that can meet our customers' requirements for fine patterning, which is important for high density mounting circuits, and high quality rolled copper foils that are 1) thin in thickness (0.007 mmt), are 2) high-precision, and 3) have good flatness.
