I will help you to file an FACR. Can you help to provide below information and fill in the DPR form attached.
1.- What is the failure symptom? Please elaborate the failure symptom in detail.
2.- When did the failure happen?
3.- How did you discover the failure?
4.- In which part of your process did you found the issue (Lab, production, quality, etc.)?
4.1- Was the device already in Field? For how long?
5.- How many units failed and how many units were used/tested by you?
6.- How did you determine the failure? Please elaborate the procedures.
7.- Does the failure unit was ever working before failure? If yes, how long had it been in use?
8.- How did you rule out that the failures were not caused by an electrical over stress (EOS) or an Electrostatic discharge (ESD)?
9.- What are your expectations of this failure analysis?
10.- Have you Re-ball your device? If yes, Is it lead-free reballing?
