Abstract
A method for fabricating wire fuse elements is provided. The method includes providing a continuously extending high resistance fuse wire having a first electrical resistivity. The method also includes applying a conductive material to the wire, and reducing the first electrical resistivity of the wire to a second electrical resistivity lower than the first electrical resistivity. The method also includes selectively removing a portion of the conductive material from the wire, and forming at least one high resistance portion having the first electrical resistivity wherein the conductive material is removed, and the wire having the second electrical resistivity in portions thereof wherein the conductive material remains.

A method for fabricating wire fuse elements comprising:
- providing a continuously extending high resistance fuse wire having a first electrical resistivity;
- applying a conductive material to the wire, thereby reducing the first electrical resistivity of the wire to a second electrical resistivity lower than the first electrical resistivity;
- and
- selectively removing a portion of the conductive material from the wire, thereby forming at least one high resistance portion having the first electrical resistivity wherein the conductive material is removed, and the wire having the second electrical resistivity in portions thereof wherein the conductive material remains.
A method for fabricating wire fuse elements comprising:
- providing a continuously extending high resistance fuse wire having a first electrical resistivity, the wire being plated with a conductive material, thereby reducing the first electrical resistivity of the wire to a second electrical resistivity lower than the first electrical resistivity;
- and
- selectively removing portions of the conductive material from the wire, thereby forming a plurality of high resistance portions having the first electrical resistivity in a plurality of portions of the wire wherein the conductive material is removed, and low resistance portions having the second electrical resistivity in portions of the wire wherein the conductive material remains.
A method for fabricating wire fuse elements comprising:
- providing a continuously extending high resistance fuse wire having a first electrical resistivity, the wire being overlaid with a conductive material, thereby reducing the first electrical resistivity of the wire to a second electrical resistivity lower than the first electrical resistivity;
- winding the overlaid wire onto a spool;
- and
- selectively removing portions of the conductive material from the wire by dipping a portion of the spool into a stripping solution such that designated portions of the overlay is removed from the wire while unaffecting other portions of the overlay, thereby forming high resistance portions having the first electrical resistivity in portions of the wire wherein the conductive material is removed.
