With all this talk of roller temperature and temperature control circuitry,
does anybody have a clue as to the optimal roller temperature for a laminator ?    Obviously would depend on copper thickness of board and how many passes through the laminator you want the board to travel.    For exactly one pass through the laminator, what would be the optimal temperature?   Or does this "exactly one pass" correspond to too high a temperature given the amount of plastic stuff found in the typical store-bought laminator?
