摘要：

The optimization of activator used in SnBi lead-free solder paste were carried out by welding experiments with the spreadability and the spot morphology as the main comment indexes. And the properties of the composite activator which was mixed by two activator possessing good performances were studied. The results indicated that the pastes with succinic acid and salicylic acid for as single activator have low wettability, the surface is easily oxidized; When (succinic acid : salicylic acid) is 2: 3, the solder paste has good weldability and the spreadabilities are 83%. The appearance of spots is regular, plump, beamy and less surface oxide.
