Electrolytic copper foil

An electrolytic copper foil optimized for installation in multilayer boards suitable for a wide range of applications, from general printed wiring boards to high-function digital devices

The electrolyte copper foil is capable of foil-making of unlimited length because a manufacturing method is adopted wherein copper is electrically deposited and wound onto a drum.The source foil lineup has thicknesses of 6 to 70 μm suitable for various applications, from general printed wiring boards to high-function digital devices.In addition, we have a lineup for lithium batteries and flexible printed wiring boards.

• High peel strength
• Good heat resistance
• Foils for flexible boards with high-temperature/high extensibility foils due to heat, and flexibility
