How to proceed to have the RMA# for 1ST280EY2F55I2LG (Stratix 10) q'ty 1pcs?

we have FPGA device (Stratix 10) failed flying probe test Q'ty 1 pcs from product NPI. After verify, we found the resistance of pin BC41 (VCCT_GXBL1C) vs pin BB43 (Gnd) is low resistance(23 Ohm)  compare good device (286 Ohm). we need to return FPGA device back to Intel for analysis. please help to review.

HI, We noticed there is similar failure analysis support request in another forum thread. May I know does it belongs to same issue here ? Same failure unit ? Seeing 2 similar forum thread is confusing to Intel right now. Can I request to close one forum thread and just maintain one forum to avoid further confusion ? The other thing is can you share with us who's your Cisco email contact so that Intel can engage with Cisco as well ? After that, we can then share the failure analysis support instruction to you. Thanks. Regards, dlim

Dear Wani,

Please find the answers inline

 

1. What is the failure symptom? Please elaborate the failure symptom in detail. 

[CTH]: Flying probe failed pin "VP1P12_VCCT_GXB" impedance abnormal. Pls see detail in FA report

2.When did the failure happen? How did you discover the failure? 

[CTH]: during Flying probe test.

3.How did you determine the failure? Please elaborate the procedures.

[CTH]: Pls see detail in FA report.

4.Does the failure unit ever working before failure?

[CTH]: Never worked before.

5.Did they violate solder re-flow temperature profiles, moisture sensitivity? Please provide the re-flow temperature profiles. 

[CTH]: Peak temperature of reflow soldering on this BGA is 236 degree C follow per supplier recommend (not over 245 degree C).

6.Did you swap the failure device to a known good board? Is the failure following the device or board?

[CTH]:we cannot swaps the component with know good board due to customer not allow to use re-ball component.  Referring verification result FA report confirm relate with BGA device.
