I most definitely remember reading somewhere that a completely "dry"
iron (free of any solder) is to be used to reflow eyelets, else the
solder will close the eyelet center making it impossible to use for
component leads later.
I do not remember where exactly i read it, or which brand of eyelets, etc..
