Equivalent One-Dimensional System for Analysis of Taper Leaf Springs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper an equivalent one-dimensional system for taper leaf springs (similar to those used in vehicle suspension systems) is developed so that results obtained from it are in good agreement ...
Non-Newtonian Squeeze Film Between Two Plane Annuli
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis is presented for the laminar squeezing flow of an incompressible power-law fluid between parallel plane annuli. The results obtained are based on the thin-film approximation, and ...
A Generalized Squeezing Flow of a Power-Law Fluid Between Two Plane Annuli
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A generalization of the problem of laminar squeezing flow of a non-Newtonian fluid between plane annular surfaces is presented. The generalization considers the effect of difference in the ...
Finite Element Method for Predicting Equilibrium Shapes of Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the development and application of a finite element method for determining the equilibrium shapes of solder joints which are formed during a surface mount reflow process. ...
Solder Joint Formation in Surface Mount Technology—Part I: Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical model of solder joint formation during a surface mount reflow process is developed in the present paper, and the solution is obtained in an explicit integral form. For two ...
Solder Joint Formation in Surface Mount Technology—Part II: Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper dimensionless design curves relating fillet height and length to joint cross-sectional area are presented for surface-mount solder joints. Based on an analytical surface tension ...
Effect of Chip and Pad Geometry on Solder Joint Formation in SMT
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical model of solder joint formation during a surface mount reflow process is developed for two-dimensional fillets whose flow may be restricted due to “finite” metallizations on a ...
Parametric Finite Element Method for Predicting Shapes of Three-Dimensional Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the application of the parametric finite element method for predicting shapes of three-dimensional solder joints. With this method, the surface of the joint is meshed ...
Prediction of Solder Geometry for an Axisymmetric Through-Hole Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solutions for axisymmetric profiles of solder joints formed between a cylindrical pin and a printed circuit board (PCB) are presented. The dimensionless differential equation governing the formation ...
