The methodology presented in this document, see Annex A for process flow, is applicable for
studying tin whisker growth from finishes containing a predominance of tin (Sn). This test
method may not be sufficient for applications with special requirements, e.g., military or
aerospace. Additional requirements may be specified in the appropriate requirements
document.
The purpose of this PAS is to:
? Provide an industry-standardized suite of tests for measurement and comparison of
whisker propensity for different plating or finish chemistries and processes.
? Provide a consistent inspection protocol for tin whisker examination.
? Provide a standard reporting format.
