As part of CALCE's Pb-free research, CALCE has released a tin whisker risk assessment software program, calceWhiskerRiskCalculator. The software allows the user to evaluate the whisker failure risk presented by a set of tin or tin based Pb-free conductors. The software implements a stochastic approach using measured whisker growth characteristics and if necessary extrapolating the growth based on measured growth trends. An example of the results from the software program is provided below.

The software can be found under the CALCE Simulation Assisted Reliability Assessment (SARA^TM) Software.
