Abstract: A method for soldering a circuit carrier to a carrier plate includes providing a carrier plate having an upper side and a first adjusting device, providing a circuit carrier having an underside and a second adjusting device, providing a solder and placing the circuit carrier onto the carrier plate in such a way that: the underside of the circuit carrier faces the upper side of the carrier plate; the solder is arranged between the carrier plate and the circuit carrier; and the first adjusting device forms a stop for the second adjusting device that limits a displacement of the circuit carrier placed on the carrier plate along the upper side of the carrier plate. After placing the circuit carrier onto the carrier plate, the solder is melted and subsequently cooled down until it solidifies and connects the circuit carrier to the carrier plate in a material-bonding manner at a lower metallization layer.
