In this study, failure analysis of the 1657CCGA package with 95.5wt%Sn3.9wt%Ag0.6wt%Cu and 63wt%Sn37wt%Pb solder pastes on lead-free PCBs with the Entek OSP (organic solderability preservative) surface finish is investigated. Emphasis is placed on determining the failure locations and failure modes of the solder joints of the 1657CCGA assemblies after they have been through 7,000 cycles of temperature cycling.
