ABSTRACT:
An electrical thick-layer fuse 10 and a method of manufacturing such a fuse is described. Here a conductive paste is printed onto a substrate 12 for the manufacture of a resistive layer 24. A dielectric layer 22 is however expediently first applied to the substrate in the manner of a podium to which the resistive layer 24 is then applied in overlapping manner. Two electrodes 14, 16 having a spacing d from one another are then applied onto this resistive layer 24, with a web of the resistive layer 24 forming a thick-film fuse being left between the two electrodes. The web width is set by laser treatment.
