The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Influence of Underfill on Ball Grid Array (BGA) Package Fatigue LifeChilakamarthi, Geetha 21 May 2004 (has links)
The influence of underfill material properties on the fatigue life of Ball Grid Array (BGA) packages that are subjected to thermal cycling is investigated in this study. A finite element model is created using Ansys by assuming the existence of an infinite array of solder interconnects, cylindrical in shape, surrounded by underfill material. Axial stresses in the interconnects are determined as a temperature loading is applied. The results show that these normal stresses are on the same order of magnitude as the hydrostatic compressive stresses induced in the solder upon underfill curing. Therefore it is concluded that for the range of underfill properties tested, these Mode I cyclic stresses need to be considered in the development of a fracture-based fatigue life model. In addition, a guideline is provided to aide researchers in designing experiments that will replicate loads on fractured specimens that are consistent with those seen in aerospace applications.

The effects of cyclic nucleotides and agents which affect their intracellular accumulation on neutrophil motilityAnderson, Ronald January 1976 (has links)
A Thesis Submitted to the Faculty of Medicine University of the Witwatersrand, Johannesburg
for the
Degree of Doctor of Philosophy, / The cell type exclusively dealt with in this thesis is the human blood neutrophil, which is also referred to in the text as polymorphonuclear leukocyte (PMN).
The experimental work in this thesis has been accomplished using one immunological and a number of biochemical investigative techniques. The former is the Boyden technique (Boyden, 1962) for the quantitative assessment of leucocyte motility. / IT2018
