Randy, are you baking initially for surface mount? These boards I'm talking about are just thru hole, so there would not be any bake between baking for part marking and wave solder.

Check J-STD-033A. You can get free copy from http://www.jedec.org. It will describe all the information including baking, storage, etc. Regarding the cycle for the baking need refer by supplier since baking will increase the oxidation rate on the b

If you bake the boards at 125 degrees celcius for about 4 hours it should work. I would also suggest that you talk to the PCB supplier to take care of this baking for you. NOTE: PCB�s with an Entek or any other type of OSP finish should not be baked.

Tran Since we all agree that J-001 has no baking requirement, why are you baking the boards? What is the purpose of this bake process?

We bake components in reels quite often using a low temp oven. If you look under JDEC standards they provide temps and baking times based off of the thickness of the part. The only problem with the low temp is that you could be looking at baking ti

Don't do it.!!!! Are you nucking futs? Why is pre-bake required? Are you producing in high humidity? Is the package of the device poroues enough to suck in moisture? Think, consider you will not get an even "bake", the outside of the reel will get

Q1: How important is the bare PCB baking ? A1: Baking boards is a non-value added activity. Q2: What is the temperature for baking @ what RH ? A2: Search the fine SMTnet Arcives for bake recipes. Q3: What would be the impact for the ENTEK finishe

Hi Stu Some seem to believe that vacuum baking will suck moisture from components and boards. Actually, the case is just the opposite. * Without proper definition and control of process parameters, vacuum baking retards the removal of moisture * Eve
