11.1 DEFINITION OF SCREENING STRENGTH. The screening strength of a given stress screen profile, denoted by SS, is defined as the probability that the stress screen will precipitate a latent defect into a detectable failure, given that a defect is present. Mathematically it can be expressed by the ratio of the mean number of observed failures
