ij] is the probability of latent failure of the j-th components of the i-th subsystem; [P.
Although both scenarios can be modeled, we consider only the main failure path as represented by the Markov chain in Figure 3 where the first failure is the latent failure and the next failure will be the primary component failure which leads to the system failure as shown by state marked "F".
Knowledge of these latent failure types could also be used as the basis for the improvement and design of incident reporting systems.
The combination of these two factors has led to a potential latent failure mode for thick film chip resistors, which has become more prevalent in the past five years.
The goal of stress testing is to accelerate latent failure mechanisms that would eventually lead to a device failure in the field.
The result is either immediate damage, or catastrophic failure of the device, but most often results as a latent failure that ultimately causes the device to fail.
Consequently, product that has no new latent failure modes should pass the screen undamaged.
If a latent failure occurs after the product is established in its market it is still possible to judge the effect of further failures and make the appropriate decision.
Ground loops can cause latent failure or immediate destruction of serial cards and other system components.
