Heat dissipation analysis under natural convection condition on high power LED
(AENSI Publisher All rights reserved, 2013-10)
As the technology downscales with superior power and increased package density, the thermal effects of the high power LED are significant. Thus, the operating junction temperature of the high power light emitting diodes ...
5mm × 5mm sized slug on high power LED stress and junction temperature analysis
(Trans Tech Publications (TTP), 2013)
Conventional incandescent lamps are being replaced by high power light emitting diode as a lighting source due to it ascendancy in terms of physical size, performance, output and lifetime. Nevertheless, the reliability and ...
Shear speed analysis on Sn-3.9Ag-0.6Cu Solder
(Trans Tech Publications (TTP), 2013)
Ball Grid Array (BGA) is a type of semiconductor interconnection used in Integrated Circuit (IC) which is being scaled down to micro and nano size. The reliability of BGA in IC becomes a concern as the size of IC reduces. ...
Low density fibrous material surface light reflectance analysis
(AENSI Publisher All rights reserved, 2013-10)
The light based surface finishing of most product measurement is an important feature in the industries. In this paper, a lab fabricated tester for investigation on the quality of low density paper which was represent by ...
FSS microchannel fluid flow profile investigation at high and low Re number
(AENSI Publisher All rights reserved, 2013-10)
The fundamental understanding of dynamic fluid flow behavior in different geometry channel is crucial due to transport phenomena influence on the key design and process control of the microfluidic systems. Recently, the ...
Microfluidic channel depth determination with Tywman-Green interferometer
(Springer-Verlag London., 2013-07)
A microfluidic channel is fabricated on a silica wafer using reactive ion etching (RIE). The depth of the microfluidic channel has been measured using a surface profilometer and a Twyman-Green interferometer (TGI) setup. ...
Shear ram speed characterization for copper wire bond shear test
(Trans Tech Publications, Switzerland., 2012)
This paper presents the evaluation of the stress and strain response of the copper ball bond during wire bond shear test using finite element analysis. A 3D non-linear finite element model was developed for the simulation. ...
Finite element analysis of thermal distributions of solder ball in flip chip ball grid array using ABAQUS
(Emerald Group Publishing Limited, 2013)
Purpose - The increased use recently of area-array technology in electronic packaging has similarly increased the importance of predicting the thermal distribution of area-array solder interconnection. As the interconnection ...
Ionic contaminations level and cleaning flip chip BGA package via a new cleaning solvent technology
(Emerald Group Publishing Limited, 2013)
Purpose - This paper aims to discuss the effects of ionic contaminations on the die surface of high lead flip chip ball grid array (FCBGA) package. Ionic contaminations from the flux residue, formed during the die attachment ...
Silica microchannel fabrication using fluorine based rie with alas a mask
(INSInet Publications, 2012-09)
The silica microchannel fabrication process has been executed with Al thin films as the sacrificial layer during Reactive Ion Etching Process (RIE). CF4/Ar and SF6/Ar plasmas has been used to investigate etch rate of Al ...
