Placement misalignment or offset Feeder pickup errors or missed parts Nozzle clog or vacuum fault

Placement misalignment or offset

Hits OEE: Quality

Symptoms: Components placed off-pad or rotated, downstream solder defects.

Vision or fiducial calibration off

Recalibrate the vision system and fiducials.

Nozzle or head wear

Inspect and replace worn nozzles; check head accuracy.

Board support or warp

Improve board support; flatten warped boards.

Prevention: Vision calibration, nozzle/head maintenance, board support.

Feeder pickup errors or missed parts

Hits OEE: Performance

Symptoms: Frequent pickup errors, missing components, machine throttles down.

Feeder misfeed or jam

Service the feeder; check indexing and tape advance.

Vacuum or nozzle clog

Clear the nozzle; check vacuum and filters.

Component or tape variation

Verify reels; manage splices and moisture.

Prevention: Feeder maintenance, vacuum/nozzle care, reel quality.

Nozzle clog or vacuum fault

Hits OEE: Availability

Symptoms: Drops parts, vacuum alarms, repeated pick failures.

Clogged nozzle or filter

Clean or replace the nozzle and vacuum filter.

Vacuum pump or leak

Check the vacuum source and lines for leaks.

Wrong nozzle for the part

Use the correct nozzle size/type for the component.

Prevention: Nozzle/filter cleaning, vacuum-system checks, correct tooling.

Stop the same fault coming back

Recurring pick-and-place stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
