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

I have an MSL3 part (a relay) supplied in tape and reel. From what I am able to determine, these parts require baking at 257 degrees F for a minimum of 8 hours once the integrity of the seal is broken for over 168 hours. How are parts baked at th

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

You might try to complete all your soldering within a 72 hour or less time frame. For all intents treat your board like a moisture sensitive component after you have baked and completed SMT reflow. Wash, blow dry, and go direct to stuffing and com

I'll answer the easy part. If you put low temperature trays in the oven at 120C, they will warp and partially melt. I have seen it more often with reels of LEDs. Someone is told to bake them before use so the put them in the batch oven and the next

I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

Hi, "Baker with controlled humidity 5%" is actually dry cabinet. Using of dry cabinets i.e. ambient temperature baking is preferred. Vacuum will always be better. If you are going to use vacuum chamber, that will be the best method in my opinion.

Hi, we have been baking parts like QFP's and BGA once they past MSL requirements. But now I have some SOIC's with MSL 3 Rating that needs to be baked. I wonder if I can bake them together with the PVC Antistatic Tubes. Can these tubes withstand the
