Both experimental and numerical analyses into the shear toughness parameter for Sn/3.0Ag/0.5Cu and 63Sn/37Pb solder ball joints are performed. The ball shear tests are conducted at the loading speeds of 200m/s and 300m/s using ball joint specimens with diameters of 300, 600 and 760 m. The failure behavior of the solder joints is quantified in terms of their fracture toughness.
Analysis of the BGA solder Sn3.0Ag0.5Cu crack interface Jun 01, 2016 · A package used by ZTE Corporation is analyzed. Considering the symmetrical structure of the chip, only 1/4 of the chip and solder joints were analyzed. Lead-free solder Sn3.0Ag0.5Cu is used in the package. The diameter of the bonding pad is 0.25 mm and the pitch is 0.4 mm. The parameters of the epoxy resin come from the product manual.
Provided is a quaternary Pb-free solder composition incorporating Sn-Ag-Cu-In, which can prevent a cost increase and sufficiently ensure proccessability and mechanical property as a solder material. To this end, indium (In) with appropriate amount is added into the Pb-free solder composition, and the addition amount of Ag is optimized, thus preventing a decrease in wettability caused by a

Jun 21, 2016 · To prevent the solder from oxidation during the melting, KCl:LiCl (1.3:1) were used over the surface of liquid solder. The melt was casted as an ingot in a steel mold. Then Sn-58Bi and Sn-3.0Ag-0.5Cu were used as starting materials to produce Sn-Bi and Sn-Ag-Cu mixed solder alloys by remelting them with different ratio.
