Migration
Dendritic Electromigration
A classic Sn-Pb dendritic growth image that works especially well for teaching 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 useful 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 especially useful for explaining how contamination, leakage, corrosion product, and eventual shorting can fit into the same progression.
Best comparison value
- Teaching contamination-assisted leakage progression
- Comparing dendrites with harmless residue
- Discussing migration-driven shorting between signals
