Understanding the Root Causes of Battery Failure

Posted by Craig Hillman on Feb 21, 2017 9:35:00 AM

The race to improve the performance and reliability of batteries is on, from electric vehicles to advances in wearables and mobile devices. In the pursuit of performance and the desire to outpace competitors, manufacturers may be tempted to overlook potential shortfalls. Most notably, Samsung made news when the company halted production of its Galaxy Note 7 and eventually scrapped the entire product after devices caught fire.

Two Most Effective Tools to Reduce Warranty Cost

Posted by Rita Mohanty on Feb 16, 2017 9:27:00 AM

In today’s high-tech world, we heavily depend on electronics for our health, safety, mobility and economic welfare. When they fail, the results can be as minor as consumer annoyance to as severe as loss of life. For these reasons, it’s necessary for all electronics manufacturers provide product warranty. A warranty, in its simplest form, means the manufacturer of the product guarantees that the product will function as expected without failure for a given period of time in a specified environment.

What 45 Years in the Electronics Industry Teaches You

Posted by Craig Hillman on Feb 14, 2017 9:28:00 AM

When considering recent advances in technology like autonomous vehicles or cloud computing, it’s easy to forget that as little as 20 years ago, most people didn’t have a home computer. The internet wasn’t fully functioning until the late 1990s and mobile access wasn’t commonplace until the dawn of the 21st century.

How to Ensure Reliability of Aerospace Commercial Off-the-Shelf Parts (COTS)

Posted by Craig Hillman on Feb 7, 2017 9:32:00 AM

NASA and the aerospace industry tenaciously pursue safety measures. The effect of various environmental factors on electronics components poses a reliability challenge for many engineers here on earth, let alone at 40,000 feet or in deep space. Components in development undergo rigorous qualification processes and extended test cycles, often repeated at extreme parametric limits and under harsh environmental conditions, and the price can be excessive.

How to Select the Right Battery for Your Application? Part 3: Common Secondary Battery Chemistries

Posted by Vidyu Challa on Feb 2, 2017 9:28:00 AM

In part 1 of this 3-part blog series, we discussed the most important metrics for battery selection. One thing to remember about battery selection is that it is essentially about managing tradeoffs. You trade off some battery metrics in order to gain in others – for example in order to gain power density, you may have to trade off energy density.

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.

In part 1 of this 3-part blog series, we discussed the most important metrics for battery selection. One thing to remember about battery selection is that it is essentially about managing tradeoffs. You trade off one feature in order to gain in another – for example in order to gain power density, you may have to reduce energy density.

Lessons Learned from the Samsung Galaxy Note 7 Battery Fires

Posted by Vidyu Challa on Jan 26, 2017 3:51:49 PM

Samsung finally released details early this week on the root cause of the Galaxy Note 7 fires and explosions that started to show up in August 2016. You can find details on the story here, but the gist of the matter is – failures and explosions started to show up with batteries from Manufacturer A, soon after the phone started to sell. Samsung provided replacement phones with batteries from Manufacturer B, but the failures and explosions continued (if you are in the battery world you would use the phrase “spontaneous disassembly”). The company had to halt production and eventually scrap the entire product.
