Nothing is missing I suppose. I was looking to see if there was another standard more appropriate to add to our POs. Something like, "all incoming material must be packaged according to J-Std-033B under penalty of death...or returned material."

Omid It depends. Follow the guidelines of ANSI/J-STD-033, Standard for Handling, Packing, Shipping, and Use of Moisture/Reflow Sensitive Surface Mount Devices. It's available on-line.

8H the only possible reaction is to bake this component?This is correctly? Many thanks for your help Nicolas

If I place a MSD level 4 open more than 8 hours in a dry cabinet

If these are moisture sensitive they are required to be shipped in a moisture barrier bag and labeled as moisture sensitive. Depending on which moisture sensitivity level (MSL) the components have, floor life can range from unlimited to a mandatory

For the proper baking durations for msd componrnts you should follow the ipc/jedec j-std-033b standard. Just google that standard and the pdf should come up. On page 16 there is a complete table showing the temps and durations.

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

I developed our company's procedure for moisture sensitive devices based on J-STD-033 and I don't recall anything requiring a certain ramp rate. Furthermore baking at 85C will greatly extend the time to reset the clock and it is harder to maintain

I completely agree. J-STD-033 spells out the "how to" of baking, quite clearly. You have to bake something for an expensively long time at 80 - 85C in order to properly desiccate your components.
