Summary

Ceramic packages for the electronic industry can be modelled as ceramic plates with a part-through center cut-out for the purpose of reliability predictions. The failure probability of such a part under mechanical loading is predicted using the NASA CARES program. The predictions are compared to results obtained from equibiaxial flexure tests for two different materials and geometries. The agreement between predictions and experiments is better for the solid plates than for those containing cut-outs. The predictions are conservative for the solid plate, but non-conservative for the plates with a cut-out.
