Answer first
Decision-oriented findings
Key findings appear before the detailed discussion so engineers and managers can quickly understand the mechanism, limits, and practical significance.

See what a typical SEM Lab technical report looks like.
Solder-Flux-Associated Failures in Electronic Assemblies demonstrates how SEM Lab connects electrical behavior, failure-site location, microscopy, elemental chemistry, process history, and evidence limits in a clear written deliverable.
This public paper is a composite technical example built from anonymized SEM Lab evidence. A client report is tailored to the submitted hardware, question, and available evidence.
What the sample demonstrates
A report is an evidence argument, not an image collection.
The value is in connecting observations to the reported symptom, testing competing explanations, and stating the conclusion at the level the evidence supports.
Traceable evidence
Images tied to analytical sites
Micrographs, EDS sites, spectra, electrical behavior, and process history remain linked so the reader can follow how each conclusion was reached.
Calibrated language
Evidence limits stated plainly
The report separates what was observed from what it means, identifies alternative sources, and avoids turning a residue or elemental peak into unsupported proof.
Inside the report
Six cases, one physical failure chain
The sample follows retained residue through different endpoints rather than treating each symptom as an unrelated category.
- Chloride-assisted copper and silver corrosion
- Moisture-sensitive electrical leakage
- Residue retained beneath low-access components
- Sequential flux-process incompatibility
- Permanent electrochemical-migration paths
- Flux entrapment compounding a plating defect
The report then converts those findings into a practical analysis sequence and manufacturing-process controls.
Engineering usefulness
From laboratory evidence to corrective action
Strong failure analysis does more than name a contaminant. It identifies the conditions that complete the mechanism and the process controls that can interrupt it upstream.
- Preserve and localize the original electrical symptom.
- Use SEM and EDS at the relevant failure site.
- Compare failed, control, washed, and unwashed conditions.
- Qualify the complete material, cleaning, drying, and coating sequence.
- Verify corrective action under the condition that produced the symptom.
