Abstract:
1. A method of making a circuit protector, comprising the steps of: providing an electrically insulating substrate having a first major surface and a second major surface opposing the first major surface; coupling a conductive element layer to the first major surface of the substrate, the coupled conductive element layer having a uniform predetermined thickness and being entirely in direct surface contact with the first major surface of the substrate; after coupling the conductive element layer, vaporizing only a portion of the conductive element layer from the electrically insulating substrate with a laser and without damaging the electrically insulating substrate and also while leaving the electrically insulation substrate intact, whereby the vaporizing of only the portion of the conductive element layer is performed to fabricate a configuration of a fuse element having a predetermined geometry and a fine edge acuity extending on the first major surface of the electrically insulating substrate.
