Creep behavior for the given Sn-3.5Ag-0.5Cu solder under single-step loading at room temperature (RT), 60 and 90 °C has been previously investigated .The relations between the applied stress and time to rupture under these single-step loading conditions are presented in Fig. 1 .As shown in Fig. 1, creep resistance for the given lead-free
the traditionally used Sn-Pb solder is being restricted (RoHS etc.) From reliability standpoints, Sn/Ag/Cu alloys has been chosen as the 1.2 Lead-free Progress for Automotive 2005-2006:Continue evaluation 2005:Start use for new designs Sn Sn-1Ag Sn-2Ag Sn-3Ag Sn-3.5Ag Sn-4Ag Sn-5Ag Sn-6Ag Whitening Ratio (%) On Ice 50 C 100 C 150 C 200 C Effects of Ga addition on microstructure and properties of Jun 05, 2014 · The effects of rare element Ga on solderability, microstructure, and mechanical properties of Sn0.5Ag0.7Cu lead-free solder were investigated. The experimental results show that Ga plays a positive role in improving the wettability and the microstructure of the solder. When the content of Ga is at 0.5 wt%, the grain size of the solder is smaller and the shear force is enhanced greatly.
Apr 15, 2019 · 1. Introduction. Due to their environmental friendliness, lead-free solder joints are widely used in the electronic packaging industry. The popular Sn-Ag-Cu system solder alloy is the alternative with the greatest potential for Sn-Pb solder replacement [1,2] because of its good wettability and comprehensive performance, and it has become the main soldering or joining material in modern Kester 495740050 Ultrapure® Lead-Free Bar Solder, Sn99.3 K100LD is a eutectic tin/copper alloy with controlled metallic dopants to control the grain structure within the solder joint and to minimize the dissolution of copper into the solder pot. - K100LD virtually eliminates the occurrence of common defects such as icicling and bridging. The improved grain structure also results in shinier solder joints than traditional lead-free alloy alternatives.
