Blow Holes After Switching from Lead-Free HASL to ENIG
After switching our PCB finish from lead-free HASL to ENIG blow holes started occurring in the solder joints of the through-hole LEDs. The PCBs and LEDs are from the same suppliers as before, only the finish changed.

A Comparison of Thermal Cycling and Thermal Shock for Evaluating Solder Joint Reliability
The industry standard for accelerated temperature cycling, IPC-9701B, defines test conditions for characterizing solder interconnect fatigue. The document specifies a maximum cycling ramp rate of 20 °C/minute to avoid thermal shock conditions that can accelerate failure modes other than low cycle fatigue in the bulk solder.
