Abstract :
The reliability of the mini-flex ball grid array chip scale package (mF-BGA CSP) was investigated. Thermal shock testing on these packages revealed that both the underfill and test board metallization play a significant role in reliability. A time-domain reflectometry method was used to detect which interface failure caused the mF-BGA CSP to fail. The predominant failure was determined to be at the solder ball/PCB interface
