Abstract
A film carrier tape for mounting electronic components or devices that excels in not only migration resistance but also adhesiveness of wiring to insulating film; and a process for producing the same. The film carrier tape for mounting electronic components or devices has seed layer comprising a zinc layer superimposed on a treated surface of insulating film and a nickel base metal layer superimposed on a surface of a zinc layer, or comprising a layer of alloy containing elemental nickel and elemental zinc in specified proportion, superimposed on a treated surface of insulating film). In the film carrier tape for mounting electronic components or devices, at least part of a region extending across a width of wiring from an edge side thereof to the treated surface of the insulating film may be continuously covered with a zinc coating layer comprising elemental zinc.
