An EBSD Study of Fatigue Crack Propagation in Bonded Aluminum Wires Cycled from 55°C to 85°C

The texture and microstructure evolution of aluminum (Al) wire bonds of power semiconductor devices during power cycling tests were investigated using electron backscatter diffraction (EBSD). Power cycling tests in pulse width modulation (PWM) mode…

Impact of routing on the EMC behavior of a GaN HEMT-based full bridge DC-DC converter

In the perspective of upgrading the SOLEIL synchrotron accelerators, new electromagnet power supplies utilized for the control of the electron beam trajectory are being studied. For those implemented in the fastest beam orbit feedback loop, a new…

Synthesis and characterization of thermally treated Co<sub>1-x</sub>Fe<sub>2+x</sub>O<sub>4</sub> (x = 0.0 –0.8) spinel nano ferrite

We report the effect of surplus-Fe-content, and thermal annealing on the properties of sol gel auto-combustion synthesized Co1 xFe2+xO4 (x = 0.0-0.8) spinel ferrites. X-ray diffraction (XRD), magnetic measurements, Fourier transform infrared (FTIR)…

Multifrequency array calibration in presence of radio frequency interferences

Radio interferometers are phased arrays producing high-resolution images from the covariance matrix of measurements. Calibration of such instruments is necessary and is a critical task. This is how the estimation of instrumental errors is usually…
