DfR Solutions Reliability Designed and Delivered

7 Months In: The Electronics Reliability Industry from a New Engineer’s Perspective

Dr. Natalie Hernandez has been a Product Engineer at DfR Solutions since November 2016. Before, she completed her PhD in Physics at Lehigh University and served as a graduate research assistant working on spectroscopic studies of rare-earth doped wide bandgap semiconductor materials, and has since made the jump to electronics reliability engineering. After 7 months in her new role, here are some of the key takeaways she’s learned about the industry.

Overcoming Qualification Method Challenges for Semiconductor Devices in Avionics Systems

When compared to the electronic systems in industries like commercial and industrial equipment, today’s avionics systems face several unique challenges. In addition to operating in rugged environments for long periods of time, they must also satisfy rigorous safety and reliability standards. Most importantly, unlike other industries, they must meet these standards while using commercial-off-the-shelf (COTS) semiconductor devices (logic, memory, etc.) and electronic assemblies that have been designed and qualified for other applications with less rigorous requirements.

How Modeling for Component Packaging Has Changed

The constant demand for smaller, faster, more reliable electronic components continues to drive innovation in component packaging. Component engineers are relentless in their quest for new and better ways to improve BGAs and packaging silicon. Recent advancements include going coreless and multi-chip modules, but silicon technology advances dictate continued improvement in packaging.

3 Ways to Mitigate Manufacturing Failure Risk

Failure is a possibility with any component on any PCB. In many cases wearout is the culprit, leaving engineers to deal with the aftermath of dissecting what went wrong and possibly re-engineering the component to avoid recurrence.

How to Eliminate the Need for Failure Analysis

Nearly one-fifth of electronics designs that are tested fail. That means nearly one-fifth of electronics designs are reworked or scrapped in favor of a new design. The resulting production delays and cost overruns mount, further threatening profitability in an automotive industry that’s already grappling with the margin-shrinking impact of increasing price-based competition.

Evaluating the Impact of Prolonged Thermal Cycling on Automotive Reliability

Automotive electronics are routinely exposed to harsh environments that introduce internal and external factors that could cause failure. Of particular concern is thermal cycling since automobiles are ideally designed to last more than a decade, during which time regular and frequently major temperature fluctuations occur. Long-term product life combined with prolonged thermal cycling present unique failure risks.

How to Predict and Prevent Automotive Power Module Failure

Just because an automotive power module has a projected 20-year life expectancy doesn’t guarantee long-term reliability. In fact, these modules are routinely exposed to vibration, shock, humidity, salt spray and other factors that can quickly degrade power and ultimately cause failure.

How Robust Designs Enhance Automotive Power Module Reliability

The automotive industry, among others, depends on power modules to house and protect delicate semiconductors and other components that power various automobile functions. Given the vital importance of power modules in relation to product reliability, a robust design must be in place in order to mitigate risk from defect, create margins and ultimately satisfy customer expectations.
