SURFACE TREATMENT LIQUID FOR COPPER MATERIAL, METHOD OF SURFACE TREATMENT FOR COPPER MATERIAL, COPPER MATERIAL WITH SURFACE TREATMENT COATING, AND LAMINATE MEMBER

摘要

A surface treatment liquid for copper material; a method of surface treatment therefor; and a surface treatment coating formed on the surface of copper material thereby. There is provided a surface treatment liquid for copper material, characterized by containing a copper oxidation etchant, a compound containing at least one metal element selected from the group consisting of Ti, Zr, Hf and Si and, as an HF supply source, a fluorinated compound. Further, there is provided a method of surface treatment characterized in that a copper or copper alloy material is immersed in the surface treatment liquid. Still further, there is provided a surface treatment coating, disposed on copper or copper alloy by the method, characterized by containing not only at least one metal element selected from the group consisting of Ti, Zr, Hf and Si but also Cu, O and F. Still further, there is provided a laminate member characterized in that the copper material with surface treatment coating and a resin layer are joined together via the surface treatment coating.
