6. We found that in actual working the operator vibrate the part while cleaning but is does not define in WI (WI-PD-15-05). So we would like to request you to add vibration while cleaning in WI and re-training operator to increase efficiency of cleaning process and protect the contamination more than standard.
7. We found in cleaning process does not arrange the area of part in each status (Waiting cleaning, finish cleaning). So we would like to request you to arrange the keeping area of part in each status to protect part mixing problem.
8. We found Dunan does not have cleaning process after processing. So we would like to request you to add cleaning process after processing and revise process sheet (Refer PU spec no. AS2300261B) to protect the contamination more than standard.
