I understand the importance of baking moisture-sensitive parts before using them in a commercial application where even 1% failure rate is unacceptable. But how sensitive are these parts really? If I'm just building hobby projects where the biggest risk is that I might have to desolder a damaged part and replace it with a new one, how much does moisture sensitivity really matter? Is it enough to just keep the parts in a sealed bag with a desiccant and hope for the best when I put them on with hot air or with drag soldering?
In other words, on a scale from 1 to 10, where 1 is "don't worry about it" and 10 is "guaranteed failure", how bad is it to throw caution to the wind and just mount my older MSL3 parts even if they haven't been baked?
