When to Use Urethane Conformal Coating

Posted by Sean Horn on Tue, May 08, 2012 @ 06:46 AM

Urethane conformal coatings are an excellent choice to use for many conformal coatingprojects.  Because of their resistance to chemical solvents, usefulness at mitigating tin whiskers, and overall hardness, they are a very popular conformal coating choice.

Tin Whisker Mitigation and Conformal Coating

Posted by Sean Horn on Tue, Apr 10, 2012 @ 09:35 AM

 WHAT ARE TIN WHISKERS

 Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from surfaces where tin (especially electroplated tin) is used as a final finish.  Tin whiskers typically grow from lengths of 1-2 millimeters (mm) but have been observed to lengths in excess of 10 mm.  Electronic system failures have been attributed to short circuits caused by tin whiskers that bridge closely-spaced circuit elements maintained at different electrical potentials.
