Abstract :
This paper describes a clustered yield model for complex surface mount technology (SMT) assemblies and multichip modules (MCM´s). Based on yield modeling techniques that have been proven in the manufacturing of integrated circuits (IC´s), this model uses the negative binomial distribution of defects to calculate board yield after test. Manufacturing data validates that this: model accurately predicts the clustering of defects and the yield predictions are significantly better than traditional binomial models
