Title:
COPPER STRIP FOR EDGEWISE BENDING, AND ELECTRONIC/ELECTRICAL DEVICE COMPONENT AND BUSBAR
Document Type and Number:
WIPO Patent Application WO/2023/277199
Kind Code:
A1
Abstract:
A copper strip for edgewise bending, which involves performing edgewise bending at a ratio R/W for a bending radius R and width W of 5.0 or less, for which the thickness t is set within a range of 1 mm to 10 mm, inclusive, and in a cross-section orthogonal to the longitudinal direction, defining, as a reference point, an intersection point of a straight line touching a surface parallel to the width direction and a straight line touching an end face perpendicular to the width direction, an area ratio B/(A+B) is within a range exceeding 10% but not more than 100%, said area ratio being calculated from an area (A) of a portion where copper is present and an area (B) of a portion where copper is not present in a square region in which the length of one side is 1/10 of the thickness t.
