John, I assume you mean 60%, not 65%. J-STD-033 has a derating table for floor life which accounts for conditions other than 30C/60% RH. Table 7-1 is what you're looking for I believe. Adam

To add to what Rob has said, Have you considered an ESD safe environment? Floors, Racks, tables, etc.... Also the humidity level of your area incase you use MSD parts? Just a thought.

Your statement is interesting, but not necessarily correct. Are shorts in the same location? Is it one short or multiple? Are there any vias in the BGA pads on the PCB? Is part MSD and handled as ESD?

YES, the role of the drying cabinet is to protect those electronic components, so that there is no need to seal the electronic components. As long as you keep the drying cabinet working properly, your electronic components can be stored indefinitely

Yes, that point remains unchanged. Just a general comment that there have been updates. e.g. re: desiccant re-use, certain devices no longer requiring bake-out, or bake times have been adjusted, and more.

Hey Dr . Klein, I think You do it all right... But here it comes: MSD; what does it really means? MS-level; what does it really means? Floor life what does it really means? I'm sorry but I can't answer all these questions right now. It is a complex m

How is RH% inside your Dry Cabinet ? What is the most critical MDL of your MSDs soldered on your board ? Best instructions about Handling of MSD you can get from Standard J-STD-033B/C. The defects you encountered at test it could be moisture absor

Paul: You are dead-on! Desiccant and nitrogen cabinets are a great way to maintain the current moisture content level of a MSD package. But if you look at the 40 degree C schedule (Table 4-1) in J-Std-003B, you will find that the drying capability o

Outside the MSD issues stated already (and I cannot provide a exact time not knowing multiple factors like Humidity levels, temps, exposure times, etc...) OSP might be the very worst finish to use in this scenario of side 1 / store on a shelf / side

I doubt that your problem is driven primarily by irregularities in your circuit board. My bet is that you’re seeing defects caused primarily by the warpage in your LGA. Consider using advice often given for minimizing warpage caused defects in BGA
