Heat produced by thin film resistive heater.

[citoca]

Hi guys. I am new to this forum and need some help in solving some problems.
My company produce thin film heater( doped tin oxide deposited on a substrate such as glass ceramic, beryllium oxide, aluminium nitride or alumina and some others). I need a formula for calculating within a few degrees the maximum temperature produced from any design given the power, voltage and size of the resistor.

Thanks

You should get the book Cooling of Electronic Equipment by Allan W. Scott.
There is no simple formula to calculate temperature rise.
