What is the maximum temperatur

Problem
What is the maximum temperature your PCB can handle? 

Solution
130 Degrees C.
266 Degrees F.

Details:
The 130 C is a sustained temperature. That is the temperature that they are UL rated for V0 (which is the highest fire rating UL has). The laminate actually starts to melt between 285 and 300 C. This is called Tg or the temperature at which the resin begins to gel.
