Creep Behavior of a Sn-Ag-Bi Pb-Free Solder
Compression creep tests were performed on the ternary 91.84Sn-3.33Ag-4.83Bi (wt.%, abbreviated Sn-Ag-Bi) Pb-free alloy. The test temperatures were: −25 °C, 25 °C, 75 °C, 125 °C, and 160 °C (± 0.5 °C). Four loads were used at the two lowest temperatures and five at the higher temperatures. The specimens were tested in the as-fabricated condition or after having been subjected to one of two air a...
متن کاملThe Kinetics of Formation of Ternary Intermetallic Alloys in Pb-Sn and Cu-Ag-Sn Pb-free Electronic Joints
A simple model of the formation of Au0.1Ni0.1Sn0.8 in Pb-Sn solder/Ni interconnects is examined by numerical simulation. Previous experimental observation has shown that after reflow the interface consists of the Ni3Sn4 alloy between Pb-Sn solder and Ni, with Au distributed through the PbSn solder ball. Au0.1Ni0.1Sn0.8 was observed to form at the Pb-Sn solder/Ni3Sn4 interface during annealing a...
متن کاملMeasuring intrinsic elastic modulus of Pb/Sn solder alloys
Young’s modulus (E) values published in the literature for the eutectic Pb37/Sn63 and near eutectic Pb40/Sn60 solder alloy vary significantly. One reason for this discrepancy is different testing methods for highly rate sensitive heterogeneous materials, like Pb/Sn alloys, yield different results. In this paper, we study different procedures used to obtain the elastic modulus; analytically, by ...
متن کاملMonoanionic Tin Oligomers Featuring Sn–Sn or Sn–Pb Bonds: Synthesis and Characterization of a Tris(Triheteroarylstannyl)Stannate and -Plumbate
The reaction of the lithium tris(2-pyridyl)stannate [LiSn(2-py)3] (py6OtBu = C5H3N-6-OtBu), 1, with the element(II) amides E{N(SiMe3)2}2 (E = Sn, Pb) afforded complexes [LiE{Sn(2-py)3}3] for E = Sn (2) and E = Pb (3), which reveal three Sn–E bonds each. Compounds 2 and 3 have been characterized by solution NMR spectroscopy and X-ray crystallographic studies. Large 1J(119Sn–119/117Sn) as well as...
متن کاملX-Ray Photoelectron Spectroscopy Study of Passive Layers Formed on Pb-Sn and Pb-Sb Alloys
In this article, passivated Pb-Sn and Pb-Sb alloys with different compositions were studied by X-ray photoelectron spectroscopy (XPS). The passive films were found to have a double-layer structure. Both Sn and Sb were found to play an important role during the growth of passive film, which resulted in different compositions of passive filJ;l1s. The Pb oxides, Pb sulfate, SnlSb oxides, and Pb-Sn...
