Hi Simond, The baking process is likely to remove any moisture after the cleaning process. We wouldn't want any moisture trapped as this might cause delamination if the package is subject to subsequent heating/reflow process. Hence there's a staging

are these requirements outlined by your company or the manufacture of the part? if its your company is the product tested? if so the test guys don't usually like to power things up with water trapped in them or under them as it can cause some problem

I am assuming that your application is Automotive. The logic here is that the product has got to at least run for 8 years or more. The prebake removes any moisture that may creep into the product during the wait time. A little moisture combined with

Hi, You might find you also need an oven & dessicant for the re-sealing & re-baking process. We found a couple of second hand Gallenkamp ovens (appear to be well made) & a Komet 20 vaccuum sealer for this. Also those natty little cards that chan

DaveP, once you shut down the oven, the moisture will start and move into the oven unless you can completely seal the oven after you turn it off. Therefore, keep the components into the oven, don't work. However, if the oven is continously on until

After a few problems and time constraints on baking moisture sensitive devices, we are looking at solutions to storage rather than going after a rebaking solution. One thing that always bothered me about baking was the oxidation on the lead finish,
