12. The device comprising:
-
a printed-circuit board; a sensor; and a heat sink connected to the sensor in a heat-conducting manner; wherein the printed-circuit board is directly connected to the heat sink at a metallic area at a surface of the printed-circuit board facing the heat sink at least one of (a) electrically and (b) in a heat-conducting manner; wherein metallic areas of inner layers of the printed-circuit board are electrically and thermally connected to at least one metallic area at the surface of the printed-circuit board facing the heat sink, and wherein metallic regions of the printed-circuit board have a higher thermal conductivity than a substrate material of the printed- circuit board substrate material to attain a temperature level which is substantially the same as a temperature of the heat sink, of areas of the inner layers which are spatially close to the sensor having distances from points of contact of parts of the sensor to the printed-circuit board less than a thickness of the printed-circuit board. - View Dependent Claims (13, 14, 15)
