With the increasing applications of flip-chip technology in the microelectronics industry, the adhesion strength of interfaces in the flip-chip microelectronic structures has become an important issue for manufacturing and operation. The existence of defects in the corresponding interfaces can gradually degrade the interfacial adhesion when the package is exposed to the high temperature and hum...

Interfaces in heterogeneous structures are typically engineered for optimal strength through the control of surface roughness and the choice of adhesives. Advances in manufacturing technologies are now making it possible to also tailor the geometries of interfaces from the nanoscale to the macroscale to create geometrically complex interfaces that exhibit enhanced performance characteristics. H...

INTRODUCTION Pedicle screw fixation in a severely osteoporotic spine remains a challenge for orthopaedic surgeons. Previous studies have demonstrated that pedicle screw fixation is highly correlated to the bone mineral density [1], and increasing the screw’s pullout strength can be achieved using a variety of methods, these include the use of pedicle screws with various designs [2,3]. However, ...

Ionic liquids exhibit a remarkably diverse interfacial chemistry. Recent theoretical and experimental results show that conventional double layers do not form on metal electrodes in ionic liquid systems, rather a multilayer morphology is present. The number of layers and the strength of adsorption are strongly dependent on ionic liquid chemical species, solutes and applied electrode potential. ...

Interfacial delamination is the major reliability issue of Quad Flat No-lead (QFN) packages under the JEDEC-MSL preconditioning and reflow process. Failures will occur when the hygrothermal stress exceeds the interfacial strength. Simulation based on finite element model is a popular method for studying the failure mechanism. However, the non-accurate material properties and lack of experiment ...

Influence of the stacking sequences of hybrid composites on the tensile strength, flexural strength, inter-laminar shear strength (ILSS) and impact energy was investigated. The hybrid glass-basalt-carbon/polyester composite laminates were processed by hand lay-up procedure at room temperature. The fracture surface of the composite laminates after the tension and flexural test was examined by sc...

in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...
