Abstract (en)
[origin: WO9511580A1] The aim of the invention is to conduct away the heat produced by the operation of a power component (10) soldered on to a circuit board (13) via a soldering surface (12). To remove the heat, through-contacts (18) are provided which are situated outside the soldering surface (12) and are electrically insulated by a length of insulation (19). These through-contacts (18) ensure good thermal contact through the floor (23) of the circuit board (13) to the heat sink (35). The length of insulation (19) ensures that the contact surface of the power component (10), which is raised to an electrical potential, is separated electrically from the contact surface of the heat sink (35), which is normally earthed. The intermediate layers (21, 22) which will also be present in a multilayer circuit board (13) of conventional design and the use of through-contacts (18) filled with tin further enhance the conduction of heat from the power component (10) to the heat sink (35).
