Webb6 maj 2013 · Scanning electron microscopic images show void formation in current crowding corners and in the skin layer of solder joints. Damage of solder joints under alternating current stressing is observed a combined process of both electromigration and thermomigration, and to be proportional to the loading frequency and current density. Webb11 feb. 2009 · Thermomigration experiments were conducted to study the change in mechanical properties of 95.5Sn–4Ag–0.5Cu (SAC405) lead-free solder joint under high temperature gradients. This paper presents some observations on samples that were subjected to 1000°C/cm thermal gradient (TG) for 286 h, 712 h, and 1156 h. It was … WebbUnderstanding the microstructural changes induced by thermomigration during thermal bonding process is important to micro-scale solder interconnects. In the present work, the precipitation of Ag 3 Sn plates in 50μm Cu/Sn–3.5Ag/Cu interconnects under thermomigration has been in situ characterized using synchrotron radiation real-time … luxury beach hotels in wales
