Why does solder paste have a shelf life?
It is highly unlikely that a properly stored solder paste’s performance is going to collapse 1 day after the expiration date. In fact, depending on the paste, it may still be good for months beyond the expiration date. As the flux degrades it loses its ability to adequately remove oxides on the solder powder.
