For the identification of Failure Modes in various packages it is often necessary to take the approach of destructive analysis using cross-sectioning.
It is a standard two process technique where the specimen is first grinded down and later polished using a fluous solution with diamond fillers.
Various metallographic investigations are carried out after accelerated ageing tests under thermal conditions such as
- Structure analysis
- Detection of delamination, cracks, technological defects etc. in components and systems
- behavior of material interfaces
- Reports on thermal fatigue
