Abstract:
The experimental results of electrical and thermal characteristics of circuit boards based on aluminum with a nanostructured layer of anodic aluminum oxide and copper conductors for assembling high-power field-effect transistors have been considered. It has been shown that the presence of a thin dielectric layer and thick aluminum base with high thermal conductivity provides a uniform distribution of heat generated by the active element over the entire volume of the board without formation of local regions with increased temperature. The experimental results have shown that the temperature gradient between the heat source and anodic aluminum oxide surface is about 17–18$^{\circ}$C at a surface heat power of 4.4 W/cm$^2$.
