Title:
METAL-CLAD LAMINATE, WIRING BOARD, METAL FOIL PROVIDED WITH RESIN, AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/071288
Kind Code:
A1
Abstract:
One aspect of the present invention is a metal-clad laminate comprising an insulating layer and a metal foil that is in contact with at least one surface of the insulating layer, the insulating layer including a cured product of a resin composition that contains a polyphenylene ether, and the metal foil being such that: a first quantity of elemental nickel measured by X-ray photoemission spectroscopy in a surface on the side of the metal foil that is in contact with the insulating layer is 4.5 at% or less with respect to the total quantity of elements measured by X-ray phtotoemission spectroscopy; and when the surface on the side of the metal foil that is in contact with the insulating layer is sputtered for one minute at a speed of 3 nm/min in terms of SiO2, a second quantity of elemental nickel measured by X-ray photoemission spectroscopy in the aforementioned surface is 4.5 at% or less with respect to the total quantity of elements measured by X-ray photoemission spectroscopy.
