Abstract

In this paper, a low temperature sintering-bonding process through in-situ formation of silver (Ag) nanoparticles using silveroxide (Ag2O) microparticles was studied. The Ag2O powders were mixed with triethylene glycol (TEG) to form a paste, which was used to bond the Ag-coated copper (Cu) bulks. The results revealed that high temperature was helpful to increase the bond strength, and the joints average shear strength can reach 21.9MPa at 523K under 2 MPa for 5 min. And the mechanism of the reaction and sintering bonding process were basically made clear by using TGA-FTIR, FE-SEM and XRD, further, a reasonable sintering-bonding model was proposed.
