What area should I enter?

Enter the total solder joint area and a list of measured void areas in the same unit family.

Does this certify acceptability?

No. It is a measurement summary tool, not an acceptance or compliance tool.

Can image-derived areas be used?

Yes. Enter areas exported from microscopy, x-ray, or image-analysis workflows.

Review notes

Segmentation threshold and projection geometry can change measured void fraction.

Methods note

Void percent equals total void area divided by joint area.

Scope and limitations

For materials research, education, and protocol documentation only. Not a certified inspection, compliance, asset-integrity, or final acceptance tool.

Results are deterministic calculations from the values entered here. Review units, assumptions, and measurement quality before using outputs in reports or protocols.

Method

Uses the tool-specific formulas and assumptions shown in the calculator output.
