Who This Unloader Fits Best

Inline AOI Lines

Best for lines that already generate pass/fail signals and need automatic separation before finished-board collection.

Quality-Critical Production

Useful where mixing good and defective boards would create rework risk, traceability issues, or manual sorting waste.

Compared with Standard Unloaders

Choose this model when you need quality-based separation, not just simple end-of-line collection.

Compared with OK/NG Buffer

An OK/NG buffer sorts boards mid-line; this unloader performs the separation at the line end for final collection.
