Method

The sample checks the factory data. The data describes the lot.

A conventional report tells you what an inspector saw in a sample. ROBION connects that sample to the factory's full-lot test stream, then adds narrow machine checks across every unit.

Three layers of evidence. One reviewed result.

Every unit, factory-run

Factory data

The factory's end-of-line results, captured as a tamper-evident stream.

AQL sample, ROBION-run

Independent sample

Tests whether the factory data and the physical lot agree.

Every unit, machine-run

Narrow 100% checks

Labels, serials, firmware and charge behaviour checked across the whole lot.

Worked example

A clean sample can still be weak evidence.

Change the lot, sample and defect rate to see why sample size and rare-defect rate matter.

Chance the sample contains at least one defect
22.1%

At this rate a clean sample is weak evidence the lot is clean. ROBION also verifies the factory's 100% data.

Matching data strengthens the result.

ROBION checks serial continuity, distributions, timestamps and outliers. A mismatch is investigated before the lot receives a result.

After review, one of three results.

Pass
Release
Evidence meets the agreed inspection scope.
Conditional
Correct
A defined issue requires action or documentary closure.
Fail
Hold
Material evidence does not meet the agreed acceptance criteria.
