Impact of aluminium addition on the corrosion behaviour of Sn–1.0Ag–0.5Cu lead-free solder
The effect of Al on the corrosion resistance behaviour of Pb-free Sn–1.0Ag–0.5Cu–xAl solder (x 1⁄4 0.2 wt%, 0.5 wt% and 1.0 wt%) in 5% NaCl solution was investigated by using potentiodynamic polarization and salt spray exposure. Passivation behaviour was evident in all the solder formulations containing Al, compared to the base SAC solder. FESEM and XRD results revealed that more dense passive ...
متن کاملDevelopment of Sn-Zn-Al Lead-Free Solder Alloys
Fujitsu has implemented a company-wide effort to progressively reduce the use of lead (Pb) and eventually eliminate this environmental pollutant from its products. As part of this effort, we have developed a new lead-free solder that consists of tin (Sn), zinc (Zn), and aluminum (Al) and yet offers superior productivity and joint reliability. The new lead-free solder has a melting point equival...
متن کاملHigh Reliability Lead-free Solder SN100C(Sn-0.7Cu-0.05Ni+Ge)
While the situation varies from country to country, nearly one year after the EU RoHS Directive came into force implementation of lead-free solder is progressing steadily. For lead-free soldering to be considered successful it is not sufficient just to have dealt with the challenges of mass production. It is also necessary to establish that the soldered joints produced are at least as reliable ...
متن کاملMechanical Properties and Solder Joint Reliability of Low-Melting Sn-Bi-Cu Lead Free Solder Alloy
The influence of alloy composition of lowmelting Sn-Bi-Cu lead-free solder alloys on mechanical properties and solder joint reliabilities were investigated. The mechanically optimum alloy composition is Sn-40Bi-0.1Cu (mass%). The addition of 40mass%Bi improves the ductility and restrains the fillet-lifting, which are problems of lead-free solders with Bi. The addition of copper improves both th...
متن کاملEffect of Antimony Additions on Corrosion and Mechanical Properties of Sn-Bi Eutectic Lead-Free Solder Alloy
The goal of the present work is to investigate the effects of the addition of Sb (0, 3 and 6 wt%) on structure, melting, corrosion and mechanical properties of Sn-Bi eutectic solder alloys. The mechanical properties of the bulk Sn-Bi-Sb solders were higher as the amount of antimony increases, making compressive strength augment from 65 MPa to 100 MPa when 6 wt% Sb was incorporated to the Sn-Bi ...
