Document Type and Number:
WIPO Patent Application WO/2011/136061
Kind Code:
A1
Abstract:
Disclosed is a laminate for flexible wiring, in which a copper plate is applied entirely or locally on a copper foil that is cladded on an insulating resin substrate, and which is characterized in that the ratio (A) of the area intensity of an X-ray peak in the X-ray diffraction on the surface of the copper plate (A = [(200)/{(111)+(200)+(220)+(311)}]×100) is larger than 90. Also disclosed is a laminate for flexible wiring, in which a copper plate is applied entirely or locally on a copper foil that is cladded on an insulating resin substrate, and which has particularly high flexibility and enables the formation of fine patterns (highly dense patterns) of a wiring line.
