The Causes of Tiny Solder Balls After Reflow
We have been seeing tiny solder balls across our boards after reflow. It appears that the solder is exploding as the balls are in areas where there is no paste or components.

Thermal Cycle Fatigue Life of Low-Temperature Solders
Thermal cycling fatigue is one of the main reliability concerns for solder. For the introduction of low temperature solders with reflow peak temperatures below 200℃, their thermal cycle fatigue life must be characterized. This paper presents a multiple component type test and time to failure data for solder interconnects formed with low temperature solders for BGAs, QFNs, and SMR component types.
