Critical Accumulated Strain Energy (Case) Failure Criterion for Thermal Cycling Fatigue of Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the automotive and computer industries, a perennial challenge has been to design an adequate and efficient accelerated thermal cycling test which would correspond to field service conditions. ...
Thermal Cycling Induced Plastic Deformation in Solder Joints—Part I: Accumulated Deformation in Surface Mount Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When an electronic package is subjected to thermal cycling, the solder joint interconnects are subjected to a complex stress system. If the stress is sufficiently large, the solder joint will ...
Determination of Stress Intensity Factors for Interfacial Cracks in Bimaterial Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A relatively simple numerical method was developed to determine the stress intensity factors of interfacial cracks in bimaterial systems. The method is based on the evaluation of crack tip ...
Deformation in Multilayer Stacked Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A linear-elastic analytical model has been developed to describe the deformed geometry of a multi-layered stack assembly subject to thermal loading. The model is based on Timoshenko’s bimetal ...
Experimental Analysis of Thermal Cycling Fatigue of Four-Layered FR4 Printed Wiring Boards
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Long-term reliability of electronic packaging has become a greater challenge as a result of ever increasing power requirements and the decreasing size of electronic packages. In this study, the ...
Effect of Localized Metal Matrix Composite Formation on Spot Friction Welding Joint Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, metal particles were added during the spot friction welding (SFW) process, a solid state sheet metal joining process, to create a localized metal matrix composite (MMC) for the ...
