I would think that ,dependent on the thermal ramp rate and the
temperautre spike at the entrance into the solder pot, you could damage
a cap if one lead enters first or if both leads enter the same way and
the part/PCB hasn't ramped up properly or the thermal rate of change
isn't even across the part. Do you have a profiler that you could attach
a thermalcouple wire to and chart what the part is seeing during the
wave process?
