At Quanta(Shanghai China) SMT Function test found 3 PCS PCBA which built the IC CTRL(1517P)5SGSKF40I3LNAC(FBGA) DRAM test fail, replaced the FBGA retest the PCBA were all passed. Verified the FBGA by the socket board, found the failure following the FBGA。So, we want to know what is wrong of these FBGA? We need ALTERA & Intel FA team support the FA request of these 3 PCS FBGA. Please help check and give the feed back ASAP. Thanks!
