Abstract (en)

[origin: WO0178453A1] An electrical device having PTC conductive polymer is made by combining electrodes, in which electroless nickel plating is formed on an electrolytic copper foil, with PTC conductive polymer. The electrodes have electroless-plated nickel layers at both sides of an electrolytic copper foil and the PTC conductive polymer is welded between the electrodes in a sandwich type.Because the electroless-plated nickel of the electrical device has even thickness, the electrical device gives improved PTC characteristics and good chemical and mechanical binding capacity between the electrodes and the PTC conductive polymer.
