Tips on Failure Analysis
Abstract
Kirk and Fred discussing doing failure analysis and the challenges
Key Points
Join Kirk and Fred as they discuss the many different issues with doing a proper failure analysis
Topics include:
- Some failures do not require a lot of investigation such as when a fork lift punches a hole through a box carrying a batch of printers.
- A failed component doesn’t always mean that it was the cause of the failure, as many times in can be the result of external over-stress, and the failed component was a victim not a cause.
- Start with the least destructive analysis, such as inspection and x-ray, before going into more invasive methods.
- A good failure analysis lab that has many customers from a variety of industries can save significant time and costs as the staff may have seen many different failure mechanisms and know the most common causes of failure.
- Fred recalls the failure analysis of an optical drive and the resulting conclusions

Here is the link to the US ARMY/CALCE PAPER presented at the 2013 RAMS conference event mentioned in this podcast– “Reliability Prediction – A Continued Reliance on a Misleading Approach” . This is a government document that is in the public domain and should be distributed a read by any engineer that believes failure prediction methodology is useful or beneficial during product development.
