        Our supplier recomends 110 deg C for 4 - 6 hours, no more than 6 - 10
boards High (1.6mm). The standard we use is 6 hours and 6 boards per FLAT
stack in our oven. I'm  uncertain what the standards say on this issue, we've
never really bothered to look it up, as we've never had moisture problems.
