Understand the Physics of Solder Joint Degradation in Board Level Reliability Vibration and Thermal Cycle Test

Board-level reliability (BLR) looks at the reliability problem in the package and PCB interconnection, which is an important topic in microelectronics. The current criterion in the BLR test is to look if the connection is open, which can only detect the failure and there is no available method that can detect the degradation of the solder joints...
