RISA Study of Process-Induced Residual Stress in PBGA Packages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Process-induced residual stresses can play a significant role in the reliability of electronic components and packages. In this paper, a practical method is developed to determine residual stresses ...
Study of Residual Stress Distribution by a Combined Method of Moiré Interferometry and Incremental Hole Drilling, Part I: Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method combining Moiré interferometry and the incremental hole-drilling method is developed to determine both uniform and nonuniform residual stress distribution in depth. The study is ...
Study of Residual Stress Distribution by a Combined Method of Moiré Interferometry and Incremental Hole Drilling, Part II: Implementation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experiment is devised to implement the combined method of moiré interferometry and incremental hole drilling which was proposed in the companion paper. A unique experimental apparatus is ...
Theoretical and Experimental Investigation on Inclined Ultrasonic Elliptical Vibration Cutting of Alumina Ceramics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Alumina (Al2O3) is an extremely hard and brittle ceramic that is usually used as an abrasive or a cutting tool insert in manufacturing. However, its growing applications in industrial products make it necessary to conduct ...
