A Study of the Influence of L-Cut on Resistance of Chip Resistor Based on Finite Element Method

Abstract

The resistance increase by transverse cutting is more quickly than by ordinate cutting when using laser trimming. Therefore, the precision and efficiency of laser trimming can be improved at low cost through reasonable design of the L-cut. In this paper, the finite element method is used to study the influence of L-cut on the resistance of chip resistor. Experiments proved that the qualitative and quantitative conclusions of the influence of L-cut on the resistance obtained by the finite element method are consistent with the experimental results. Thus, using the conclusions of the influence of L-cut on the resistance obtained by the finite element method can provide the control basis for improving the trimming precision and trimming efficiency.
