Speaking Of Reliability: Friends Discussing Reliability Engineering Topics | Warranty | Plant Maintenance

Phantom Test Results Abstract Dianna and Fred discuss phantom test results in reliability testing. Key Points Join Dianna and Fred as they discuss phantom test results and the challenges of reliability test methods. Topics include: The importance of root cause analysis for test failures. How test rigs and measurement systems themselves can give false positive […]

Sample Size Considerations Abstract Dianna and Fred discuss sample size considerations for reliability testing. Key Points Join Dianna and Fred as they discuss sample size considerations, tackling the frequently asked question: “How many samples do I need?”. Topics include: Understanding the trade-offs between desired reliability/confidence levels and the massive sample sizes often required. Balancing statistical […]

Fault trees are very useful ways to visualize the logical relationship between events ... like which combinations of components need to fail for a system to fail, or which potential root causes need to occur for an undesirable event to occur. We tend to teach fault trees to unsuspecting students to solve only one type of problem ... and this is wrong! Want to learn more?

Dismissing Failures Abstract Chris and Fred discuss a common problem of dismissing or ignoring failures, especially when they don’t fit your ‘profile.’ Key Points Join Chris and Fred as they discuss the problems and hazards that arise when a failure occurs and is ignored. This can be tricky, as it can sometimes be hard to […]

Join Enrico and Fred as they discuss the pros, cons, and pitfalls of designing and running a test that has no failures, or does.

Traditional Reliability Methods Abstract Kirk and Fred discuss a question from a listener about why traditional reliability methods don’t work for modern electronics. Key Points Join Kirk and Fred as they discuss why traditional methods, such as those based on prediction using classical references like Military Handbook 217F don’t work with today’s electronics.. Topics include: […]

Adhesives Abstract Kirk and Fred discuss the reliability issues around using adhesives to attach mechanical assemblies. Key Points Join Kirk and Fred as they discuss the use of adhesives and testing the long-term reliability of adhesive bonds. Topics include: Mismatched coefficients of thermal expansion (CTE) pose a significant challenge for attaching glass, metals, and polymers. […]

How do you take into consideration the number 'starts and stops' your item goes through during it's life when it comes to characterizing reliability? It's important ... but are there any rules that can help?

It turns out that electric vehicle (EV) batteries appear to be lasting longer than the laboratory tests the manufacturers use suggest they will. Why is this? Has something changed? ... or is there something wrong with the laboratory testing? ... or something else?

How to use data from connected devices for derivation of mission profiles Abstract Enrico and Fred discuss the value of using real-world usage data to define mission profiles, advocating for a shift from deterministic to stochastic approaches. They touch on the impact of environmental conditions, the risk of selection bias in data analysis, and weigh […]
