PROBLEM TO BE SOLVED: To provide a method of determining a mechanical gravure aptitude and a Ballard separation aptitude that have not been determined by a conventional Vickers hardness evaluation method.;SOLUTION: By the determining method, the mechanical gravure aptitude and Ballard separation aptitude are determined from tensile strength and elongation percentage of a stress-elongation curve obtained when a copper piece in a dumbbell shape obtained from copper-plated coating is pulled at a fixed speed by a tensile tester until the copper piece is ruptured instead of management using indentation hardness, such as conventional Vickers hardness.;COPYRIGHT: (C)2012,JPO&INPIT
