Method of trimming thermistor or other electrical components and the contacts thereof

Abstract From the Canadian patent

A thermistor or other electrical component has electric contact material applied on at least one surface; the surface having the contact material is positioned over the surface of a supporting substrate; the substrate may carry two conductors to which the contact material on the component should be electrically connected; in one embodiment of the invention a gap is, formed to extend through the substrate through which gap an abrading element may extend for abrading the contact material, thereby to form two contacts from the unitary layer of contact material and also to shape the resulting contacts; alternatively the layer of contact material may be removed by a laser beam projected through …
