- There are gold layer damage issue as well. Please add the photo and actions into the 8D report. Below photo for your reference. They are not related to Sn on gold surface so you need to take actions.
- The AVI parameter fine tune are able to detect the gold surface issue, please specify how to optimize and different before & after.
- For permanent corrective action(s) for Non-detection, please consider to do sampling baking and reflow inspection for each lot to ensure no gold fingers reliability issue
- In the verification of effectiveness, please provide the target date of new batch/new date code shipment for validation.
- Please translate the report into English version
- Missed gold plating issue is still pending for 8D report update.
