See J-STD-033 for helpful background and information. If you don’t use the parts within 5 days you simply bake them at a temperature and time to remove moisture, then your 5 days restarts. Or, store them in a low humidity environment such as dry nitrogen. Counterfeit parts are rampant. You can x-ray and electrical test and compare to known golden units as first steps. | |

Components are shipped in a moisture-sensitive way because the moisture-sensitive soldering process (reflow oven) is by far the most common one. | |
