Hello,

Please support with this issue.

Component information:

Part Number	ADV-5050535001
Description	IC LOGP FBGA1517 10AX115N4F40E
Manufacturer	ALTERA
MPN	10AX115N4F40E3VGAB
QTY	11 pcs
Serial Number	FE05325; FE05312; FE05326; FE053B8; FE052FD; FE05406; FE0581A; FE05816; FE05819; FE05824; FE05818; FE05812; FE05813; FE0582C; FE05817.
DC	2031, 2037, 2125, 2113

Problem analysis:

• These units failed Base Component Test – Verify BIST on clock devices 0,4, 5, 6 and 7 due to faulty BGA’s.
• Prior to BGA replacement, all cards were sent to x-ray inspection and there were no soldering issues found.
• Each BGA received a 7 digit code in order to trace them after re-balling.
• All faulty BGA’s were re-balled and placed on different units, but the defect was the same.
• After BGA replacement, the units passed all tests.
• ADVA R&D’s response regarding this matter is that the failing FPGAs have defective transceivers working marginally.

Test result: 

                               Failed Base Component Test - Verify BIST: Clock DEV
