Good day, Technet

After reviewing past threads regarding baking boards before conformal coating I come up with quite a varied selection of ideas.
I found 1 hour @100°C, 4 hours at 150°C, and 4-5 hours at 125°C.
My design engineer is concerned about the boards being exposed to this temperature for an extended time. Yes, in the wave solder it sees much higher temperatures... for a short period of time.  Our aqueous wash system dries at about 65°C for 20 minutes.
Our product normally is tested to 40 - 50°C depending on the customer needs.
The past threads suggested raising the temperature above 100°C to "boil off" any remaining water.

Can this time/temperature be narrowed down any? 

And if we use a lower temperature are we possibly trapping moisture? 

How will the reliability be affected by these elevated temperatures.

Thanks in advance,

Phil Nutting
