High-Reliability Low-Ag-Content Sn-Ag-Cu Solder Joints for Electronics Applications

TL;DR: In this article, the effect of minor alloying elements on the solder joint reliability of low-Ag-content SAC alloys in terms of thermal cycling and drop impact was evaluated.

Microstructure, mechanical, and thermal properties of the Sn–1Ag–0.5Cu solder alloy bearing Fe for electronics applications

TL;DR: In this article, the effect of Fe addition on the microstructural, mechanical, and thermal properties of the Sn-1Ag-0.5Cu (SAC105) solder alloy was investigated, and it was observed that the Fe-bearing solders significantly suppress the coarsening of the Ag 3 Sn IMC particles; consequently they exhibit stable mechanical properties.

Effect of Ag content and the minor alloying element Fe on the electrical resistivity of Sn-Ag-Cu solder alloy

TL;DR: In this paper, the authors investigated the electrical resistivity of the high-Ag-content Sn-3Ag-05Cu, the low-Ag content Sn-1Ag-5Cu, and the high and low Ag-content Quaternary solder alloys, and found that both the Ag content and the addition of Fe significantly affected the electrical resistance.

The influence of solder composition on the impact strength of lead-free solder ball grid array joints

TL;DR: Cu BGAs exhibit the least resistance in both shear and tensile tests among the four compositions of solders, which may result from the cracks in the IMC layers introduced during the reflow processes.

Drop impact test - mechanics & physics of failure

TL;DR: In this article, the physics of failure in board-level drop impact have been investigated and three finite element analyses have been performed to understand the failure in drop impact: (i) velocity impact of a PCB -model as a beam; (ii) velocity impacts of a drop assembly with centrally mounted package and (iii) impacts of solid elements with submodeling.

A review of board level solder joints for mobile applications

TL;DR: This review focuses on the drop-impact reliability of lead-free solder joints that interconnect the integrated circuit (IC) component to the printed circuit board (PCB) and tin-rich lead- free solders exhibit significantly higher strain rate sensitivity than eutectic SnPb solder.
