The current standards to assess the tin whisker susceptibility of lead-free finishes in electronic components are problematic. Key problems include lack of data collection, lack of agreement on proper techniques for measuring whisker length, lack of established acceleration transforms for prescribed tests, and disagreement over acceptance criteria. This paper overviews the tin whisker standards and then describes the problems listed above. Recommendations for improvements are then presented and discussed.</p> <p><b>Index Terms:</b> Environmental test, lead-free electronics, standard, tin whisker.</p> <p><a href="../../fulltext/2009/ShibutaniOstermanPecht.pdf">Complete article</a> is available to CALCE Consortium Members.</p> <p><font size="-2"><font color="red">&copy; IEEE.
