On the serious side, and this one's extreme, you can encounter interesting times with solderability moisture sensitivity, etc. In some cases, depending on solder termination area metallization coating and device packaging (in what were the devices stored - under what conditions upon sealing), terminations may remain solderable if they ever really were. Beyond that, shoot craps, the designer, yourself (last, bad, and never choice), and/or the customer.
