A New Creep Constitutive Model for Eutectic Solder Alloy
In this study, a large number of creep tests were carried out to study the effect of stress level and testing temperature on the creep behavior of 63 Sn/37Pb solder in a systematic manner. Based on the dislocation controlled creep mechanism and Gibbs’ free-energy theory, a new creep constitutive model was proposed. The model was found to describe accurately the creep flow of the solder and to b...

متن کاملLow cycle fatigue analysis of temperature and frequency effects in eutectic solder alloy
Low cycle isothermal mechanical fatigue testing of a eutectic alloy 63Sn/37Pb was carried out in a systematic manner over a wide range of frequencies (10–1 Hz) and temperatures (240 to 150°C) with the total strain set at different values (1–50%). The low cycle fatigue behavior of the eutectic solder was found to be strongly dependent on test temperature and frequency. If the Coffin–Manson model...
متن کاملA Modified Energy-based Low Cycle Fatigue Model for Eutectic Solder Alloy
Surface mount technology (SMT) is increasingly used in microelectronics to mount components by soldering onto the printed circuit board (PCB). The solder alloys are used as the electrical and mechanical connections between the component and the board. Fatigue failure of solder joints is recognized as a major cause of failure in electronic devices. An approach to this problem is to determine the...
متن کاملSuperplastic Forming of Inconel Alloy 718spf
Superplasticforming (SPF) has become an important manufacturing method for aerospace and fuselage components. The basic reasons for the popularity of this process are reviewed and the compatibilityoffine-grained INCONELB alloy71 8SPF@ to superplasticforming are presented in this paper. The temperature limitations of current aluminum and titanium alloys employed in SPF parts for gas turbine comp...
