Effect of IMC thickness on thermo-mechanical reliability of lead-free solder joints in solar cell assembly

Zarmai M.T., Ekere N.N., Oduoza C.F., Amalu E.H., University of Wolverhampton, UK

The fatigue failure of lead-free SnAgCu solder joints in solar cell assembly is studied to determine the effect of thickness of intermetallic compound (IMC) layer on the reliability of the joints. Finite element modelling (FEM) [...]

A Multiscale Modeling Approach for Microelectronic Packaging Applications

Iwamoto N., Hölck O., Noijen S., Wunderle B., Todd S., Honeywell Specialty Materials, US

With increasing complexity of the systems and ongoing miniaturization, structural dimensions cross over from the micro- to the nanoscale. At this scale, conventional simulation methods are overtaxed: On the one hand, the continuum approach fails [...]

Anac O., Basdogan I., Koc university, TR

Micro Electro Mechanical Systems (MEMS) are the new and emerging technology of the future and have many applications on different disciplines like biomedical, imaging technology, biology etc. Characterization of motion and vibrations of such systems [...]

Optimal Design of Laser Surgery for Cancer Treatment Through Nanoshell-Mediated Hyperthermia Therapy

Feng Y., Rylander N., Bass J., Oden J.T., Diller K., The University of Texas at Austin, US

Recent development of nanoparticle technology and its application in hyperthermia therapies makes it possible to consider optimal control of the temperature field and thermal energy delivered to the tumor region with minimal destruction of surrounding [...]

Geometrical Effects in Mechanical Characterizing of Microneedle for Biomedical Applications

Aggarwal P., Johnston C., University of Calgary, CA

This paper discusses the design and implementation of MEMS microneedle with emphasis on integrated functionality for sensing the forces. The idea is based on the requirements of strength, robustness, and minimal insertion pain and tissue [...]

Coarse-Grained Molecular Dynamics for Nano-Design

Rudd R.E., Lawrence Livermore National Laboratory, US

The design of nanoscale mechanical systems poses a novel set of challenges for modeling and simulation. The need for an accurate model of the nanoscale components is clear. This can be of the form of [...]

Modeling of the Deformation of Living Cells Induced by Atomic Force Microscopy

Rudd R.E., McElfresh M., Baesu E., Balhorn R., Alleny M., Belak J., Lawrence Livermore National Lab., US

We describe finite element modeling of the deformation of living cells by atomic force microscopy (AFM). Cells are soft systems, susceptible to large deformations in the course of an AFM measurement. Often the local properties, [...]

Modeling and Characterization of an Integrated FET Accelerometer

Kniffin M.L., Wiegele T.G., Masquelier M.P., Fu H., Whitfield J., Motorola, Inc., US

The GFET accelerometer is an integrated inertial sensor based on a movable-gate field effect transistor. The complexity of the transduction principle and the tight tolerances associated with its manufacture necessitated a large range of simulation [...]

Modeling and Design Optimization of a Novel Micropump

Klein A., Matsumoto S., Gerlach G., Dresden University of Technology, DE

The purpose of this paper is to give an overview about the design process of a new-type micropump. Four different coupled physical domains must be considered. The coupling effects on the pysical level are modeled [...]
