The Physics of Failure: Predicting Reliability in Electronic Components

A lot has been written about Moore’s Law and the potential limitations of semiconductor design and manufacturing in the future. Can we really continue to double the number of transistors on a given-sized die every eighteen months? For the last 30 years, Moore’s Law has held, but, we may be seeing the real limitations to future semiconductor development and to Moore’s Law — severely shortened operational lifetimes of advanced chips. That, in turn, creates massive reliability problems for critical embedded systems in the future.

Measuring the Color and Appearance of Special-Effect Paint

Manufacturers that design, formulate and apply coatings have struggled for years to find a rigorous and easy-to-use method that reliably measures the color and appearance of special-effect paints. Companies tried to relate measurements taken with handheld spectrophotometers that collect colorimetric data from several in-plane angles to events that occurred in production processes, but these instruments, by their nature, could not collect the essential data points to yield reliable results. Other companies have tried to skirt the problem by creating a coarseness index or “sparkle” metric that relies on photographic images taken in-plane, but this method is easily confused and insufficient for rigorous analysis.

Mass Flow Controllers Ensure Astronauts Have Medical Fluids On Demand

Quantim Coriolis mass flow controller Brooks Instrument Hatfield, PA 215-362-3527 www.brooksinstrument.comTransporting medical fluids that are manufactured on Earth into space is expensive and logistically challenging, so researchers at NASA’s Johnson Space Center sought a way to manufacture medical fluids in space. The Quantim Coriolis mass flow controllers from Brooks Instrument were chosen by NASA contractor ZIN Technologies for measuring water flow through a purification system to a standard IV bag that was prefilled with salt crystals and a magnetic lab stirrer. The Quantim devices are making their way into space to ensure that astronauts have medical fluids on demand for emergency needs.

Rotary Motors Customized for Telescope Spectrometer

SQUIGGLE® custom rotary piezoelectric motors New Scale Technologies Victor, NY 585-924-4450 www.newscaletech.comThe Wide-Field Multi Object Spectrometer (WFMOS) is a ground-based astronomical instrument that is scheduled to be commissioned on the Subaru Telescope on Mauna Kea, Hawaii in 2013. The WFMOS, along with corrective optics, will be mounted in place of the secondary mirror of the telescope. An array of NASA Jet Propulsion Laboratory’s Cobra fiber positioners will feed light from a 1.5-degree field of the sky to a visible spectrometer, for red shift observations of 2,400 cosmological targets simultaneously. The light will be transferred to the spectrograph using 2,400 f/2.4 fibers with 107 μm cores.

High-Speed Cameras Assist in Crash Sled Testing

The Kettering University Crash Safety Center (Flint, MI) conducts vehicle subsystem tests using a pneumatic deceleration sled. The research and testing includes frontal, rear, or side impact occupant protection systems containing airbags, pretensioners, and/or child safety seats. The sled system can carry up to a 2,000-pound payload to a speed up to 42 miles per hour, and reach peak decelerations over 70 Gs. Access to high-quality imagery and dependable on-board and off-board high-speed digital video is as vital to the success of the data collection as is the anthropomorphic test devices (ATDs, also known as “crash dummies”) and their instrumentation (Figure 1).
