Lead-free solder alloys samples

Table 2 Metallographic preparation for lead-free solder alloy samples...

The NCMS project developed a large data set of the mechanical properties of lead-free solder alloys. For three Pb-free solder alloys and eutectic Sn Pb, these include creep data, constitutive equations, and microstructural data, as well as detailed descriptions of test methods, sample geometries, and material data for the components and boards used in the experimental testing, as listed in Table 15. Partial datasets for 75 additional solder alloys were generated and are included in the NCMS CDROM [2]. 

Failure analyses by destructive techniques also revealed many differences between tin-based lead-free and tin-lead solder alloys. Even the preparation methods for failure analyses are different. Alternative sample preparation is re-...
