Hi Barrie,
There is no such thing as a generalized accelerated reliability test or
reliability model. Both the testing and the modeling need to be specific for
the failures you are interested in, e.g. solder joints,plated-through
holes/vias, components, insulation resistance, etc. You certainly can test
product in some Burn-In test, which would be some worst-case operating
condition, but that would tell you little about long-term reliability. An
appropriate reliability assurance program needs to include 'Design for
Reliability (DfR) ', which assures that quality product will meet your
relability goal in its service environment, and controlled processing, which
assures quality product.
