I have level 3 components per J-STD-20. 1) Are there any packaging methods which can be "zip locked" instead of heat sealed? 2) Do I need to evacuate the bag? 3) Do I need to purge with Nitrogen?

Did you ever change the passwords on the oven or were they defaults and you dont remember them? Because for level 1 is the number 1 for 2 it is 2 and for level 3 it is 3. Hope this helps.

In my case most of the PCBs are OSP finishing and worst case of MSD component on bottom side is level 3 (168 hours). You mean that PCB shelf life with bottom side assembled shoud be 84 hours?

I have a MS level 3 component that has been on the shelf for 7 years. Should it be baked before usage. The HIC card reads ok- and it was stored with desiccant. History of the part is unknown, was purchased from franchised distribution.
