The physical processes of arc erosive micromachining and the influence of trimming on the parameters of resistors have been examined, and thin film resistors without trimming are compared with those trimmed by arc erosion and laser beam machining.In the paper a theoretical model for arc erosion of thin films is proposed. The optimal conditions of arc erosive trimming are determined. The shape of the cuts are recorded and examined. The applicability of arc erosive trimming with respect to stability is proved. A measuring method is introduced for resistors trimmed by arc erosion using a direct current generator.
