FPGA based SPWM Bridge Inverter
(Science Publications, 2007)
This study presents methodology to generate sinusoidal pulse width modulation (SPWM)
signal using Field Programmable Gate Array, FPGA technology. We discussed the unipolar switching scheme and the methodology to generate ...
The characterization of Al Bond pad surface treatment in Electroless Nickel Immersion Gold (ENIG) deposition
(Science Publications, 2007)
This study reports a number of experiments that were designed to characterize aluminum
bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment ...
The surface morphology characterization of electroless nickel immersion gold under bump metallurgy (UBM) using SEM
(American Institute of Physics, 2007-05-09)
This paper presents the surface morphology characterization at each process step in electroless nickel immersion gold (ENIG) deposition using Scanning Electron Microscope (SEM). The characterization start at initial bond ...
