Size Up Component Defects Nondestructively


Acoustic microscopic imaging can locate internal defects in packaged integrated circuits (ICs) and other components without physically damaging the package. The microscope's transducer sends a pulse of ultrasound into the sample. The pulse is reflected, partly or entirely, by material ...

Sizing Up the Benefits of Quantum Computers


Computers have come a long way in recent decades, driven by the power available in microprocessors. Intel co-founder Gordon E. Moore at one time (in a 1965 technical paper) proposed that the number of components in an integrated circuit (IC) or microprocessor would double each two years ...

Measuring Losses in Switch-Mode Power Supplies


Switch-mode power supplies are known for efficiencies that can run into the high 90 percent range, a far cry from the 50-60 percent efficiencies one may expect from the older technology of linear power supplies. Power-supply efficiency is a measure of how much energy is wasted between ...
