I believe ovens are how chips are soldered onto boards in large numbers. Boards were assembled, run through an oven, then tested to see if any of the components were fried. (Board Assembly and Test = BAT) Any boards that failed the test were run through another oven upside down so that the components would fall out when the solder melted, and then tested individually to see if any could be recovered. So, basing the motherboard in an oven, it could certainly work, but it's defenitly something of a Hail Mary if you don't know the temperature tolerances of all the components on the board. -- John D.
