摘要

摘要: 具有纳米结构的有机-无机笼型硅氧烷齐聚物（POSS）作为强化相的POSS/Sn-3.5Ag复合钎料可有效地改善基体钎料钎焊接头的力学可靠性。在前期试验的基础上，采用差热分析试验的方法分析了POSS 质量分数为3%的POSS/Sn-Ag复合钎料中POSS颗粒的熔化特性。结果表明，3% POSS/Sn-Ag复合钎料的熔化温度与Sn-3.5Ag共晶钎料相近，POSS颗粒的加入对其熔化温度影响不大，说明复合钎料在熔化特性上可以满足工艺性能的要求。此外，差热分析计算表明，3% POSS/Sn-Ag复合钎料在冷却过程中具有更高的表观活化能值，说明POSS强化相可能主要存在于Sn晶粒的晶界处。

Abstract: Nano-sized polyhedral oligomeric silsesquioxane-TriSilanol cyclohexyl (POSS) particulates reinforced Sn-3.5Ag composite solder joint could improve mechanical reliability. The 3% fraction of POSS reinforcement is the best weight fraction. The welding characterization of POSS reinforcement in 3% POSS/Sn-Ag composite solder was analyzed through differential scanning calorimeter (DSC) analysis based on former experimental results in this paper. Results indicate that the welding temperature of 3% POSS/Sn-Ag composite solder is similar to that of Sn-3.5Ag eutectic solder, so 3% POSS/Sn-Ag composite solder has acceptable processing property. In addition, according to DSC analysis, 3% POSS/Sn-Ag composite solder has higher activation energy. It demonstrates that POSS reinforcements might be present in the Sn boundaries.
