Sample and analysis objective
When the sample strategy excludes laser preprocessing, evaluate a plasma-only route and use stage records to control removal and target exposure.
| Item | Case information |
|---|---|
| A13-marked sample | Approximately 4 hours; plasma only, no laser |
| Another package sample | Approximately 3 hours; plasma only, no laser |
| Nature of the time records | Records for the displayed samples, not universal cycle times |
Sample A · Four stages of decapsulation
Four stages follow the A13-marked sample from an intact package to completed decapsulation. This plasma-only case used no laser and recorded approximately 4 hours in total.
Sample B · Before and after decapsulation
A separate package is shown before and after treatment. This plasma-only case recorded approximately 3 hours.
Result review priorities
- Assess plasma-only suitability based on material and package thickness.
- Record intermediate stages; do not control the endpoint by elapsed time alone.
- Review target-region residue, surface changes and subsequent electrical requirements separately.
