Inhalt:
The effect of a novel solent, CELTOL-IA, on sintering behaviors of micro-silver paste was studied to realize pressureless sintering at lower temperature. A bonding strength of above 30 MPa was achieved at 180 °C with these big silver particles. A low electrical resistivity of 8.45 muOmega · cm was also realized at the low temperature, which was superior to that of those nano-silver pastes. The special themal reaction of new solvent was attributed to the electrical and bonding performances. The new micro-silver paste could be a good candidate of expensive nano-Ag paste as die attaching material for high power device packaging.
