| Abstract: | BGA is a new concept of contemporary assembly technology. BGA has developed and innovated the SMT/SMD since it appeared. It is believed that BGA will be the best choice of the IC with density, high performance, multiple function and high I/Os. The acceptable criterions, solder defects and reliability of BGA solder joint are discussed here. Especially a disputed defect behavior void will be analyzed in detail. Some suggestions of improving BGA solder joint quality is also discussed. |
