Supplier's Category: All Failure Analysis: Root-cause investigation of broken components
Failure analysis is the root-cause investigation of a broken component — working backward from a failed part to determine exactly what went wrong and why, using techniques ranging from visual inspection to electron microscopy. It’s reactive, engaged after a failure has already occurred.
Failure analysis value depends heavily on preserving the failed part’s evidence, so how a sample is handled before it reaches the lab matters as much as the lab’s technique.
- Ask how to properly package and preserve a failed part before shipping it, so evidence isn’t destroyed in transit
- Confirm the lab’s technique range (visual, SEM, chemical analysis) matches your suspected failure mode
- Check whether the report includes actionable root cause and corrective action recommendations, not just a description of the damage

When failure analysis gets engaged
This service gets called in reactively, after something has already gone wrong.
- Field returns: understanding why a shipped product failed in customer use
- Production quality issues: root-causing a defect appearing on the line
- Warranty and liability disputes: independent analysis to establish what actually happened
