RELIABILITY EVALUATION, ASSESSMENT AND FAILURE ANALYSIS

formation of dendrites from
the migration test
defective area of through-hole

analysis using cross-sectional photos


Characteristics of the Migration Tester


  • Observation of dendrites and CAF (both surface and internal layers)
  • Elemental analysis of dendrites and CAF
  • Analysis of the crystalline structure of dendrites and CAF


Analysis of Connections


  • Cross-sectional observation of cracks in the solder connections
  • Nondestructive observation of delaminations of solder connections
  • Elemental analysis of the alloy used in solder connections


Analysis of Buildup


  • Observation of buildup construction of multilayer boards
  • Observation of delaminations


Analysis, Evaluation and Advisory for Preventative Measures


It is imperative to establish a solid preventative measure based on the results of the failure analysis in order to improve product reliability and quality.


We provide advisory services for developing a sound prevention measures drawing upon accumulated testing data and experience.
