摘要

The soldering reaction and interfacial microstructure formed between liquid Sn-Zn-Ag solder and Cu at the early stage of soldering at 250 deg C for 15 s were studied primarily with the aid of transmission electron microscope (TEM). To achieve the early stage reaction information, the soldered specimens, 5 mm x 5 mm x 500 |xm solder on 10 mm X 10 mm X 20 mu m Cu, were rapidly quenched in liquid nitrogen after soldering. The results of TEM interfacial analysis show that a Cu-Zn reaction zone, consisting of beta'-CuZn and gamma-Cu_5Zn_8, formed near Cu while a Ag-Zn zone, consisting of gamma-Ag_5Zn_8 and epsilon-AgZn_3, formed near solder. The innermost layer adjacent to the Cu substrate is an amorphous Cu-Zn diffusion region that contains dispersed beta'-CuZn nanqprystalline cells. The beta'-CuZn also precipitates in the gamma-Ag_5Zn_8 and epsilon-AgZn_3 layer due to the supersaturation of Cu.
