Integration of the NIST and SURDAT Databases on Physical Properties of Lead-Free Solder Alloys

Abstract

The electronic SURDAT database published in 2007 (available freely from the website www.imim.pl/english ) is being integrated with the NIST database (available freely from www.boulder.nist.gov/div853/lead_free/solders.html ) to provide a single source for data on lead-free (Pb-free) soldering alloys. The NIST database was developed to support circuit board designers, and so it is focused primarily on mechanical properties. In contrast, the SURDAT database is focused primarily on thermophysical properties. Together, they will form a much more complete source for the properties of Pb-free solder alloys.
