The Best Method to Calculate Risk of Failure and System-level Effects

One of the key problems in today’s electronics industry is the constant changes in needs and deliverables. Today’s electronic devices are smaller and faster and are constantly exposed to changing environmental conditions. With more people putting electronics closer to a human body in the form of wearables such as iPhones, Fitbits, or heart monitors, electronics designers and manufacturers need to ensure the safety and reliability of these devices to avoid costly mistakes.

Here, at DfR Solutions we work with hundreds of electronics manufacturers across industries and have noticed an increasing number of companies reporting early life failures in the field or unexpected failures in tests due to solder fatigue. They're noticing that the classic solder fatigue calculation models do not seem to capture all the possible risks of failure.

3 Real Life Examples Of “After A Failure” Investigations


“After a failure” investigations are typically performed to identify root cause of failure, calculate risk exposure and develop mitigation and remediation solutions. Just like with “before a failure” investigation, there are two specific test methods that could be applied to either of the two categories – non-destructive physical analysis (NPA) and destructive physical analysis (DPA).
