  • a. providing a substrate having a top, a bottom and opposing sides, the opposing sides each having a groove therein;

    b. depositing, upon the top of the substrate, a first conductive layer to simultaneously form a fusible link and terminal pads at opposite ends of the fusible link, the fusible link and terminal pads being electrically connected; and

    ,c. applying a protective layer, wherein the protective layer is a layer of polymeric material which is applied as a gel and is smoothed across the upper surface of the supporting substrate and the fuse link to provide the polymeric material with a substantially flat upper surface.
