Been there, ... done that,...got the T-shirt. When with a major IC manufacturer, we tried this. IT DIDN'T WORK! The problem was that most convection ovens leak. We could not achieve a significant N2 atmosphere.Eventually went to vacuum-assisted bak

I have two basic questions: 1. We have a number of small convection ovens and want to modify some of these for baking out parts when needed. We have tried pumping nitrogen into these but I still run between 35 and 50 RH. Has anyone tried converting a

One thing we did for our oven is hook it up to the compressed air system in the factory and bled in a small volume of air to create a positive pressure in the oven. The air is clean (non-oiled) and comes off the dryer. We can attain 5% RH. Remembe

Larry, You can try one of two approaches, a bake above 100C will drive off moisture or use a vacuum bake. The vacuum bake process is slow since there is less/no air to conduct the heat. In the hybrid industry the standard vacuum bake was 16 hours at

Dan: Until I got deep into development of a vacuum assisted moisture removal process, I always thought that the bake process would be saddled by the lack of atmosphere in the chamber. I later learned that the conduction of temperature at reduced atm

N2 PPM vs %RH? With a firm grasp of the obvious, reflow oven manufacturers rig N2 ovens differently than non-N2 ovens. The N2 displaces O2. Usually N2 oven monitor something or other to give an indication of N2 ppm. %RH really isn't part of the eq

We use dry boxes manufactured by DMS Clean Room Products in Lawrence, MA. The phone number on the tag is (508)683-2325, but I think their area code changed to either 978 or 781 recently. We flow dry nitrogen through the box in order to ensure that
