| 摘 要： | 以SnAgCu无铅焊膏铺展性能和焊点形貌作为评价的主要指标,通过回流焊接实验,对常用于焊膏的10种溶剂进行了单一溶剂优选,并对两种性能较好的溶剂进行复配优化研究.结果表明:A醇、二缩三乙二醇和B醚作为单一溶剂时焊膏的润湿性较好、焊点外形较饱满,铺展率都大于83%;A醇和B醚按质量比3:2复配时得到的焊膏铺展率达到93%...

| Abstract: | The optimization of 10 solvents used in SnAgCu lead-free solder paste were carried out by reflow soldering with the spreadability and the spot morphology as the main comment indexes.And the properties of the composite solvents which was mixed by two solvents possessing good performances were studied.The results indicate that the pastes with A alcohol,B ether and triethylene glycol as single solvent have good wettability,plump spots,and the spreadabilities are all over 83%.When ζ(A alcohol:B ether) is 3:2,the solder paste has good anti-slumping ability and the spreadability is above 93%.The appearance of spots is regular,plump,beamy and less surface oxide. |
