. This paper documents an investigation to determine the impact of voids in BGA and CSP components using thermal cycle testing (-55°C to +125°C) in accordance with the IPC- 9701 specification for tin/lead solder alloys

Weibull slopes. Failure Analysis The -55/125 °C thermal cycling test started substantially after the 0/100 °C test, and only samples from the 0/100 °C cycle were available for failure analysis at the time of this writing. Examples of void-assisted solder

. That helps to prevent propagation of crack at the solder joint in thermal cycling. As found below, SB6NX shows much higher sheer strength than SAC305 with ENIG and OSP substrate alike
