Hybrid Microwave-Assisted Rapid Sintering Process for Fabrication of Sn-0.7Cu+1.0wt.%Si₃N₄ Composite Solder

Abstract:

Hybrid microwave-assisted powder metallurgy sintering process is an emerging technology in synthesizing composite solder. In this study, a combination of microwave-energy heating and radiant heating from SiC crucible (so called hybrid heating) for the powder metallurgy sintering process for fabrication of Sn-0.7Cu+1.0wt.%Si₃N₄ composite solder was developed. The influence of different microwave power output with and without SiC crucible on the heating rate was measured. The effect of the increasing microwave exposure time on the microhardness values of Sn-0.7Cu+1.0wt.%Si₃N₄ composite solder sintered pellets were also measured to correlate the effect of heating behavior of the hybrid microwave-sintering and the present of the sintering mechanism within the green compact samples. It can be observed that the increasing of microwave power output has marginal effect to the heating rate of the setup. Higher heating rate using optimum power output (800 W) can be realized with the present of SiC crucible (susceptor material). The results revealed that the microhardness of the Sn-0.7Cu+1.0wt.%Si₃N₄ green compact decreases as microwave exposure time is increased. While, minimal microhardness value changes after 3 minutes (230 oC) using the 800 W of microwave exposure time.
