Abstract

An improved method of manufacturing thick film chip resistors in mass production is described. By applying two or more resistance layers per chip resistor, less variance in the eventual resistance value is obtained if the resistors are manufactured in mass production using substrate plates. Less variance in the resistance value implies less trimming activity, which leads to a considerable cost reduction. Moreover, the use of two or more sub-layers enables application of TCR compensation by applying a resistive material having a positive TCR for one sub-layer and a resistive material having a negative TCR for the other sub-layer.
