Symmetry energy of nuclear matter at low densities and clustering at the nuclear surface
(IOP Publishing Ltd, 2012)
We present a density functional theory which connects nuclear matter equation of state, which incorporates clustering at low densities, with clustering in medium and heavy nuclei at the nuclear surface. This explains the ...
Wire bond shear test simulation on sharp groove surface bond pad
(Trans Tech Publications, 2012-12)
Wire bonding process is first level interconnection technology used in the semiconductor packaging industry. The wire bond shear tests are used in the industry to examine the bond strength and reliability of the bonded ...
Polymer core BGA stress analysis at minimal vertical loading
(Trans Tech Publications, 2012-12)
Ball grid array is an interconnection method widely used in the electronic packaging industry. The reliability of the solder ball is being improved by introducing new materials for the solder ball. In this study, the stress ...
Shear ram height investigation for gold wire bond shear test
(Trans Tech Publications, 2012-12)
This paper presents the simulation of gold wire bond shear test. The stress and strain response of the gold ball bond during wire bond shear was examined. The simulation was done using a A 3D non-linear finite element ...
