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.

Hello Aerin...welcome Actually you have already found a very important web site for your research. Go to the SMTnet archives and do a search. You will find a wealth of practical information. After that, go to the IPC or the JEDEC website and downlo

What is the MS-level and floor life of the critical components (should be written on the MSD-bag)? What is Your climate condition in the production area (%RH, temp.)? Are you doing this inspection on every board or is it enough to do it on the first

Referring to IPC/JEDEC J-STD-033B.1 section 3.3.2.2 'The amount of desiccant used, per moisture barrier bag, shall be based on the bag surface area and WVTR in order to limit the interior relative humidity in the MBB to less than 10% at 25°C.' So wha

Let me explain. At 125 degrees C, the oven is above the boiling point of water. It will be vaporized and eventually be vented from the oven. However at temperatures of 90 degrees c and lower the relative humidity becomes an issue. For the life of me,

Dave, if you have a level 6 then you have no other option then to bake it and reflow before it exceeds the specified floor life. For more details check out the joint IPC/JEDEC standard J-STD-033. It can be downloaded for free at http://www.jedec.org.

Mikeal�s approach is one of the more cautious ones. IPC/JEDEC J-STD-033 clause 8.6 talks about 200�C body-temperature not to be exceeded and how it�s best measured. If you go for that method and you made sure that in your wavesoldering (that�s what

In regards to baking an assembly prior to hot air (BGA) rework.... 1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-br
