Claim One:
1. A computer implemented method for analyzing durability of electronic components, the computer implemented method comprising: creating a first finite element model for a chassis for the electronic components; creating a set of second finite element models for a set of printed wiring assemblies for the chassis; combining the first finite element model with the set of second finite element models to form a combined finite element model; performing a finite element analysis of the combined finite element model to determine a response of the combined finite element model to a vibration spectrum to form results, wherein vibration loads are applied in the finite element analysis through a mounting location for the chassis and propagate through attachment points for the set of printed wiring assemblies in which the attachments points are points at which the set of printed wiring assemblies are attached to the chassis; extracting vibration levels at part locations for the set of printed wiring assemblies from the results to form extracted vibration levels; and performing a fatigue analysis for solder connections and leads in the set of printed wiring assemblies using the extracted vibration levels to identify the durability of the electronic components.
