Impacts of Cooling Technology on Solder Fatigue for Power Modules in Electric Traction Drive Vehicles: Preprint
This paper presents three power module cooling topologies that are being considered for use in electric traction drive vehicles such as a hybrid electric, plug-in hybrid electric, or electric vehicle. The impact on the fatigue life of solder joints for each cooling option is investigated along with the thermal performance. Considering solder joint reliability and thermal performance, topologies...
متن کاملContact Fatigue
CONTACT FATIGUE is a surface-pitting-type failure commonly found in ball or roller bearings. This type of failure can also be found in gears, cams, valves, rails, and gear couplings. Contact fatigue has been identified in metal alloys (both ferrous and nonferrous) and in ceramics and cermets. Contact fatigue differs from classic structural fatigue (bending or torsional) in that it results from ...
متن کاملNumerical and Experimental Evaluation of Residual Stress and Fatigue Strength of Steel CK35 in Shot Peening Process
In shot peening process the work piece surface is struck by a large number of balls and compressive residual stress is generated on the surface. So, mechanical properties such as fatigue strength, stress corrosion resistance, smooth shape and ... will improve. In this paper, the balls with a speed of 100 to 200 m/s were struck on the steel samples and fatigue strength compared with specimens wi...
متن کاملIntelligent-speed-increasing Spindle Using Traction Drive
INTRODUCTION Recently, a milling for die using a small end mill of diameter less than 1 mm is increased, because sizes of plastic mold parts such as connectors for an IT and an electronics becomes micro extremely. In general, a tool life is long and a good cut surface is obtained as a cutting speed is high. A speed-increasing spindle, which is attached to a shank may be used to increase the cut...
متن کاملImpact of Drive Strength and Well-contact Density on Heavy-ion-induced Single Event Transient
We measure distributions of heavy-ioninduced Single Event Transient (SET) pulse widths from the 4 kinds of inverter chains to measure their characteristics and estimate SET-induced soft error rates on a Flip-Flop (FF) and a delayed TMR FF. Test chip was fabricated in 65-nm bulk CMOS process and measurement results show that maximum SETinduced soft error rate on a FF is equivalent to 20% of Sing...
