Hi Sebastien,
- Found on the center piece
We found center part have rust about 6-8 % total from Step 1.1 - 8 (QC).
- What we believe is the origin
We think the problem come from new worker have sweat effect to metal when he touch with finger.
- The step where it comes from
Rust come from Step#1.1
- The action taken to prevent it
We must to use glove on step#1.1 and 1.2 or all way take parts with Tweeszer
- The process the clean the CP between step 1.1 and 1.2
1) Now the worker who have sweat effect must to use glove all the time when he take the part.
2) We cleaning center part and niddle already on step# 1.1, 1.2 , 2 and 3.
2) Effect from this problem have clear about 6 days
