COPPER FOIL HAVING GLOSSY SURFACE WITH EXCELLENT OXIDATION RESISTANCE AND METHOD OF MANUFACTURING THE SAME

摘要

TO ESTABLISH A TECNIQUE OF FURTHER IMPROVING THE OXIDATION RESISTANCE OF THE GLOSSY SURFACE OF A COPPER FOIL THAT HAS A COMPOSITE LAYER CONTAINING CHROMIUM, ZINC, AND PHOSPHORUS ON ITS GLOSY SURFACE IS ACHIEVED BY A COPPER FOIL HAVING EXCELLENT OXIDATION RESISTANCE CHARACTERIZED BY A COMPOSITE LAYER CONTAINING CHROMIUM, ZINC, PHOSPHORUS, AND NICKEL FORMED ON THE GLOSSY SURFACE OF THE FOIL AND ALSO TO A METHOD OF MANUFACTURING THE SAME BY ELECTROLYSIS.
