Model for reliability prediction of thick film resistors

Abstract

A model for time-to-failure prediction based on component parameter drift is described. The idea for creation of this model is based on the influence of time-dependent random and non random factors on the distribution of the random variable.The reliability interpretation of the data from thick film resistor ageing tests has been completed with the model developed. Two different drift functions are described for two ruthenium-based thick film methods with equal resistivity 10s2/square.
