Migration
Dendritic Electromigration
A classic Sn-Pb dendritic growth image that is a clear example of the difference between electrically meaningful conductive growth and incidental residue.
Interpretation
Why this image matters
The dendritic morphology is visually clear, which makes the image a reference for training engineers to recognize conductive growth rather than treating all surface residue as equivalent.
The report context confirmed Sn-Pb electromigration between several pins and also noted associated corrosion product with chlorine and bromine, supporting a contamination-enabled migration mechanism.
That makes this image a strong reference for explaining how contamination, leakage, corrosion product, and eventual shorting can fit into the same progression.
