Tin Whisker Risks and Mitigation
Bright tin finishes can spawn whiskers under stress; mitigation includes matte finishes, alloys and conformal coating.
Why they grow
Compressive stress and intermetallics drive whisker formation.
Mitigation
Matte tin, bismuth-doped tin and coating suppress growth.
Where it matters
Space, medical and high-reliability demand whisker controls.
Key Takeaways
Key Takeaways
- Bright tin can grow whiskers.
- Prefer matte or alloyed tin.
- Coat high-reliability assemblies.
