"If they complain just tell them it�s no different than finding the stray smt components that appear from time to time and makes me wonder why no one complains about them." Because they know, even as they're vacuuming up those stray Rs and Cs, that

There is no standard for time above liquidus. It is described rather broadly by the solder paste supplier. Reflow Zone: If the temperature is too high, boards may char or burn. If the temperature is too low, cold and grainy solder joints will resul
