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.
