摘要

The heat-sink interfacial reaction of Sn-90Pb, Sn-95Pb, Sn-37Pb solders are contrast with the Sn-3.0Ag-0.5Cu solder in vacuum soldering and reflow soldering in this paper, to find the matching solder combination. Results show that, Sn-90Pb, Sn-95Pb solders are not the good choices for Al2O3/MoCu in vacuum soldering. Sn-3.0Ag-0.5Cu and Sn-37Pb solders can be used in the vacuum soldering, and Sn-37Pb solder is the best choice as the leaded solders for space use.
