OK, Here's a quick and dirty way to find out moisture 
          content:
          
          1.   Measure the PWB then weigh it.
          2.   Bake the PWB for 24 hours at 250 deg F.
          3.   Weigh the PWB again.
          
          The difference between the weights divided by the area (or 
          volume) of the PWB will give you the moisture content.  
          Baking above the boiling point of water will drive off 
          moisture, and 24 hours is a good amount of time to drive off 
          enough moisture to give you a realistic number.
