we bake boards 80~120 deg-C @1hr, after in-line DI wash. oven setting to 90 deg-C, as +/-5 deg-C, tolerance against door open/shut fluctuations = "temperature loss". If anyone has evidenced procedure, that shows no need for baking, pray do share wi

We don�t bake between routine washing between soldering cycles. We bake when we immediately go to test or box-build. Certainly, it all depends on your process, materials, and boards. So, how did you determine that you needed to spend the money? I

I have two cases where I must bake after DI wash. The moisture entrapment is specifically within microprocessor sockets. Without air gun blow out and baking, oxidation occurs that causes flaky contacts for the PGA. We will bake for 2-3 hours @ 60C. O

I have question about board baking after in line washing machine then I would like to know some information that ; 1) Do we need board baking after in line washing machine? Both bare board and assembly borad normally we don't bake . 2)In case of ne

I thought Dan saw the delamination after wash - not baking? What temp are your dryers on the washer set at?

BOARD BAKING SCHEDULE: Bake time depends on the board thickness and construction. For laminated FR4 PCB, we bake between 6 and 24 hours at 100�C. ROOT CAUSE OF THE PROBLEM: Heating moisture entrapped between the laminations of the board too quickl

I experienced assembled boards delaminated after washed. You know...those old datecode PCBs that I was talking about a few weeks back ? I was forced to use it, and of course prior using it I've baked them. I've baked them at 125 Deg for 4 hours and/

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
