Initial printing and drying to 125C will be performed at another lab, therefore I would not be bringing in a liquid, but a dried form already on wafers. I would like to run them through their cure cycles in AW610_r at 600C and 900C respectively. Please let me know, Nate -------------- next part -------------- A non-text attachment was scrubbed...

I don't believe the AW610's were designed to run for that length of time (Ed should correct me, but I think the maximum is about 5 minutes). Your application and needs may be different, but I'm wondering if the AW610 is your best option. We do have a programmable muffle furnace outside the lab which might work for this, although the cycle times (due to thermal mass in heating and cooling) can be long. Let me know if you're interested in the furnace.

I talked to some of the techs at Koartan, they said it really just needs enough time to reach equilibrium at temperature, not even the full 10 min. My understanding is that 10 min is on the long end of RTA work, but doable... I can forward you the datasheets if you would like. If the furnace you mention can do relatively quick runs, that would be acceptable. Because of other parts in my process, I am trying to minimize time at temperature because I'm running into diffusion issues. I tried a run in my lab's high temp furnace (which takes about 5 hours to do a 900C cycle) and other parts of my sample didn't survive. I've also run them through short durations (3 minutes at 925) and they do survive that. I'm happy to come in to talk to you about this tomorrow too, at any time. Let me know, thanks, Nate On 1/31/2011 11:03 PM, Mary Tang wrote: > Hi Nate -- > > Just a quick look at the applications notes on the Koartan website > suggests cure/firing times of 30-60 minutes at the target > temperatures.
