What You May Have Missed

It’s been a couple weeks since our annual Design for Reliability Conference took place at the Sheraton Inner Harbor Hotel in historic Baltimore, but I’m still reflecting on the captivating speakers and their insights, in addition to the invaluable networking that took place. With over 100 attendees, there were many fascinating conversations to be had, and I’m looking forward to advancing those relationships, both old and new.

Reliability in Avionics: Using Virtual Prototyping, Simulation and PoF

Posted by Lloyd Condra on Mar 28, 2017 8:56:48 AM

Modern electronics have continued in the pattern of Moore’s Law which has decreased transistor size and increased performance. This necessitates development of faster, smaller ICs with greatly reduced power dissipation. However, the increased number of transistors in smaller spaces causes higher power density which can lead to higher failure rates, shorter device lifetimes and unanticipated early device wearout.

How to Evaluate Integrated Circuit (IC) Components for High Reliability Applications

Posted by Ashok Alagappan on Mar 23, 2017 9:24:00 AM

Most of the microcircuits used in Aerospace, Defense and High Performance (ADHP) applications today are commercial-off-the-shelf (COTS) components targeted for markets other than ADHP, with required lifetimes that are typically significantly shorter than those of ADHP applications. COTS component manufacturers evaluate their components’ expected lifetimes in the target applications, but provide little or no information for ADHP applications. Thus, it is the responsibility of the ADHP user to conduct the appropriate analyses and, where necessary, mitigate for shorter-than-required lifetimes.

How Physics of Failure Helps Bring Reliable Avionics Products to Market Faster

Posted by Ed Dodd on Mar 21, 2017 10:58:39 AM

Global avionics is enjoying a period of rapid growth that, when coupled with the relatively low cost of entry into the industry, makes it a very attractive option for new players. This increasingly crowded and competitive landscape makes it even more important to be first to market with new technologies, which can leave less time for reliability testing.

What is Physics of Failure?

Posted by Dr. Randy Schueller on Mar 14, 2017 9:23:00 AM

Product performance and reliability are non-negotiables in defense applications. It’s a statement as true now as it was during World War II, when the U.S. military experienced significant malfunctions in aircraft electronics. Then, reliability engineering was just being introduced and focused on metal fatigue and fracture, and solutions were often time-consuming, expensive and ultimately ineffective. These initial efforts, however, spurred a  shift to electronics reliability prediction simulation and testing that served as the basis for the Physics of Failure (PoF) approach that is common in many industries today.

Integrating Physics of Failure (PoF) into Complex Systems

Posted by Ed Dodd on Mar 7, 2017 7:41:00 AM

Ensuring that a product will perform and function as promised is the key to any manufacturer’s success in the marketplace. As systems become more complex and intricately designed, and as manufacturers rush to be first-to-market, the challenge of performing accurate and timely reliability testing increases, as was demonstrated in recent newsworthy technology failures.

Implementing Physics of Failure in Electronic Boxes

Posted by Chris Montgomery on Jan 31, 2017 9:22:00 AM

The performance of many electronic components is only as good as the enclosures that surround them. Reliability prediction of an electronic box is a crucial and sometimes underappreciated element that directly affects the performance of the circuitry and other costly systems inside.

Facing the Challenges of Self-driving Vehicle Technology

Posted by Craig Hillman on Jan 25, 2017 9:36:00 AM

Automakers like Ford, GM, Volvo and Tesla made major strides in 2016 for autonomous vehicle technology, and are closer to making driverless cars a reality for the average consumer. Meanwhile, Uber made news when they introduced self-driving fleets to the public. While driverless cars may not be pulling into most driveways in the immediate future, it’s clear the race is on.
