Application of worst case analysis to failure analysis of hybrid IC
the root cause of component failure is usually due to manufacturing defects or external overstress,but there is a situation in hybrid IC which is cannot find the corresponding manufacturing defect or overstress when it failure,this kind of failure is often because of the system of the hybrid IC triggered the worst working condition when it running.When the electrical parameters of the components in the hybrid IC run into a worst combination by coincidence,it will lead to some components in system stress than their own abilities which they can afford,then the failure happened,that is to say,system of hybrid IC goes into worst case working conditions.Therefore,when the failure case shows randomness or elusive,we should fully consider the possible of the worst working conditions in system.This paper detailed introduction the worst case analysis(WCA)applied through a failure analysis case of a hybrid IC.
