How to Ensure Electronic Product Reliability When You Don’t Have Time to Test

With today’s rapid product development cycles and time-to-market pressures, there’s not always time to perform reliability testing. This situation leaves many manufacturers with the question of how to ensure their products will be dependable when reliability testing and the possible resulting re-engineering are too time consuming or expensive.

Solder Joint Reliability — Exposing the Weakest Link

Electronic systems may often fail, not because of poorly designed chips, substrates or other components, but because of the failure of the solder joints that link them all together. The mismatch between PCB solder materials can result in thermal expansion problems including excessive strain, cracking and open circuits. The impact of thermal fatigue, soldering defects, vibration and residual strains must be considered when analyzing solder reliability. These and other issues are often exposed in accelerated stress tests.

Two Most Effective Tools to Reduce Warranty Cost

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

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)

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.
