We recently ran into a situation where a SMT header with tin plated tails would not wet properly during reflow. Someone told us that tin plating has a shelf life and needs to be re-tinned after a length of time. I have not heard of that before. Does anyone have any experience or know any specifics regarding shelf life of tin plated components? Can anyone provide any references about this subject?

Tyco had a good read on the shelf life of tin plating and the different variables involved in determining it's shelf life.
