FIELD: radio engineering, in particular, manufacture of printed circuit boards. SUBSTANCE: connection strips on the substrate are made in the form of a meander with a section, having the shape of a trapezoid, they are made of metal with resistivity $$$ Ohm m; a protective layer of heat-insulating material is additionally placed on the surface of the connection strips. Changing the material and thickness of the substrate and protective layer, as well as the section and area of contact with dielectric, it becomes possible to control the rate of heat flow. EFFECT: improved design. 1 dwg
