Neural-fuzzy machine learning approach for the fatigue-creep reliability modeling of SAC305 solder joints

Weibull reliability distribution and ANOVA analysis

The experiment was performed with seven replicates in each condition, and the fatigue life data were collected when the solder joints underwent complete failure. A two-parameter Weibull distribution was implemented to analyze the reliability performance at each experimental condition based on the obtained fatigue life. The fatigue life was measured as the number of cycles that the solder joint survived before failure. Failure was defined as the complete fracture in the bulk solder joints or in the intermetallic compound (IMC) layer. The…
