Title:
SURFACE-TREATED COPPER FOIL, COPPER-CLAD LAMINATE, METHOD FOR PRODUCING PRINTED WIRING BOARD, METHOD FOR PRODUCING SEMICONDUCTOR PACKAGE AND METHOD FOR PRODUCING ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2016135924
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a surface-treated copper foil capable of removing a copper foil at a good cost without requiring etching treatment and damaging the profile of the surface of the copper foil transferred to the surface of a resin substrate when removing the copper foil from the resin substrate after sticking of the resin substrate to the copper foil.SOLUTION: There is provided a surface-treated copper foil which comprises a copper foil having no roughened particles and a surface roughness of Rz of 0.1 to 5.0 μm as measured in accordance with JIS B0601 (1994 year) and a release layer which is provided on a surface of a copper foil having surface unevenness and makes a resin substrate peelable when sticking the resin substrate to a copper foil from a release layer side, where the surface-treated copper foil is used for a method for producing a resin substrate which comprises a step of sticking the resin substrate to the surface-treated copper foil from the release layer side and a step of peeling the surface-treated copper foil from the resin substrate without etching to obtain a resin substrate in which the surface profile of the copper foil is transferred to the peeling surface or a method for transferring the surface profile of the copper foil to the resin substrate.SELECTED DRAWING: Figure 1
