Please tell me the story of this part, how you discovered that it is fails? How it was measured?
Please share with me this details so we can move further ;
1. What is the failure rate? What is the failure rate vs. tested sample? Example: 2 out of 100 units.
2. What is the failure symptom? Please elaborate the failure symptom in detail.
3. When did the failure happen? How did you discover the failure?
4. How did you determine the failure? Please elaborate the procedures.
5. Does the failure unit ever working before failure?
6. Did they violate solder re-flow temperature profiles, moisture sensitivity? Please provide the re-flow temperature profiles.
7. Did you swap the failure device to a known good board? Is the failure following the device or board?
8. Is this a prototype build or volume/mass production?
9. Kindly provide quantitative investigation result that could proof the failure is Intel FPGA induced.
Please do not share confidential information publicly. If you required private message, please do let us know.
Same procedure here.
I will initiate private message discussion with you for FA analysis support on EP4S100G5H40I1N device.
