Abstract:
A method of manufacturing a chip fuse includes the steps of depositing a plurality of columns of electrically conductive metal film on a green, unfired ceramic substrate, and disposing a plurality of wire elements on the substrate over the film columns and perpendicular to the film columns. A cover of green, unfired ceramic is bonded to the substrate over the wire elements and film columns to form a laminate. The laminate is then die cut into individual fuses, which are then fired to cure the ceramic and form an intermetallic bond between the wire elements and the metal film. End termination coatings are then applied to the fuses to facilitate connecting the fuses in an electrical circuit. The invention relates to a chip fuse manufactured according to the method.
