Verification starts before the laboratory
Source context, order details, traceability documents, component lifecycle and application criticality should be reviewed before deciding which physical tests add meaningful evidence.
Layered methods
- Visual and packaging review for markings, labels, condition and consistency.
- X-ray for selected internal construction evidence without opening the package.
- Decapsulation where destructive die/construction comparison is justified.
- Electrical or functional verification when meaningful parameters and suitable laboratory methods can be defined.
No single universal test
A quality plan should state acceptance criteria, sampling, methods and deliverables. Test choice depends on the exact device and sourcing risk.
How to use this guide
- Use it to narrow product families and sourcing requirements.
- Confirm exact electrical, mechanical and environmental values against the latest manufacturer datasheet.
- Provide the exact manufacturer part number / ordering code when requesting availability.
