Plain-language definition
Chemical damage that degrades metal contacts, traces, or components.
Why it matters
Liquid-exposed devices may keep failing until corrosion and its underlying contamination are addressed.
Technical detail

Examples
- Green residue around a connector can indicate copper corrosion after liquid exposure.
