Is anyone out there familar with Rogers 5880 teflon laminate?  I am 
     processing a double sided board that comes out curled up when it exits 
     the reflow oven.  The use of a fixture to hold the board flat during 
     the process and allowing it to cool in the fixture does not help.  
     When you try to straighten the board out the result is cracked chip 
     components.  I would appreciate any help that you can give me with 
     this situation.
