    Abstract: The present invention relates to an electric and/or electronic circuit including a printed circuit board (20), at least one separate circuit board (10) and at least one power connector (12) for said printed circuit board (20). The at least one power connector (12) is connected or connectable to a corresponding counterpart. A number of electric and/or electronic components (22) is sold at the separate circuit board (10). The at least one separate circuit board (10) is connected to the printed circuit board (20) by a number of solder joints (16). The solder joints (16) are connected to the separate circuit board (10) by a through-hole-technology. The solder joints (16) are connected to the printed circuit board (20) by SMD (surface mount device) technology. At least one power connector (12) is fastened at the separate circuit board (10) by the through-hole-technology.
