   A complex method of the stationary temperature field identification in a multilayer hybrid Low Temperature Cofired Ceramic (LTCC) structure has been presented. This procedure includes computer simulation of the temperature field and its experimental verification. Different configurations and mutual placement of heat sources in the microcircuit have been taken into account in simulation process. Laboratory verification of the computer simulation is based on point measurements with use of thick-film precision thermo-elements and an infrared radiation detection method. The verified inaccuracy of the stationary temperature field simulation is less than 10%.
