Tell me about a time when the wrong part or orientation is placed on the board. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed setup verification, first-piece result, and machine log and coordinated the action to verify feeder setup, nozzle condition, polarity, rotation, and program revision. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
