HIGH FLEXUOUS COPPER FOIL AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: A copper foil having improved elasticity and a manufacturing method thereof are provided to apply a copper foil to the bent portion of electronic devices. CONSTITUTION: A copper foil(40) is manufactured by treating the surface of an unprocessed copper foil by depositing copper particles through electroplating. It takes 80% of entire copper particles, the ratio of short diameter to long diameter is 0.4~0.9. Organic impurity content is 0.5% or less.
