A method of forming an electrical circuit on a surface of a substrate, the method comprising:
- providing a substrate having a surface with at least one groove formed therein, the groove having a bottom textured surface;
- and
- applying an electrically conductive material onto the bottom textured surface of the groove.
A method of forming an electrical circuit on a surface of a substrate, the method comprising:
- providing a substrate having a surface;
- forming at least one groove within the surface of the substrate, the groove having a bottom textured surface;
- placing a masking film against the surface of the substrate;
- subsequently removing portions of the masking film to expose the grooves;
- applying at least one layer of a first metallic material onto the bottom textured surface of the groove;
- and
- applying at least one layer of a second metallic material onto the layer of zinc.
