Lead-free, High-temperature, Fatigue-resistant Solder

CD-ROM of NCMS Project No. 170503-96034 (August 2001)

Electronic assemblies are used not only in office-type environments, but in application environ­ments that range from -55 to 160°C. To meet this temperature requirement, and to join in the worldwide push to eliminate toxic materials (lead) from electronic assemblies, NCMS embarked on a four-year collaborative, multi-partner effort to develop and evaluate lead-free solder alloys that would meet the harsh-environment requirements of the automobile, avionics, oil drilling, and military industries. Project team members considered 241 solder alloys in terms of toxicity, manufacturability, cost, reliability, and availability. After careful evaluation against these criteria, they found 7 lead-free alloys that exhibit performance superior to both tin-lead and tin-silver eutectic solders at -55 to +160°C. The study results are available as a final project report delivered on a compact disk. The report (100+ pages) contains more than 50 graphics, tables, and photos, several in color.
