Tin Whisker Spreadsheet
The Whisker Risk Model Spreadsheet can be used to calculate the expected number of tin whisker shorts on one or more leaded components, based on user-specified part and lead geometry, whisker density, tin whisker length distribution, applied voltage, and conformal coating coverage. The expected number of shorts is displayed numerically, as is the reliability for not shorting. In addition, graphs depicting the user-specified whisker probability density functions (PDFs), calculated whisker spacing PDFs, and calculated bridge interference PDFs are provided.
The Tin Whisker Risk Spreadsheet was developed by
BAE Systems under funding from the
Department of Defense's Strategic Environmental Research Program (SERDP), WP-1723. For more information please
