1. A device for transferring at least partly ferromagnetic electronic components from a dispensing carrier to a receiving substrate, wherein the device comprises:

  • a first holding fixture for the dispensing carrier, which is configured and arranged to hold the at least partly ferromagnetic electronic components on a side of the carrier facing the substrate,a second holding fixture for the receiving substrate, which is configured and arranged to receive one of the components at a place predetermined for the one of the components on the substrate,a first actuator that is configured and arranged to move and/or to swivel the first holding fixture, and a second actuator that is configured and arranged to move and/or to swivel the second holding fixture,a detachment unit, which is configured and arranged at least to support a detachment of one of the components in each case from the carrier, in order to transfer it to the substrate,a magnetic arrangement, which is positioned relative to the second holding fixture for the substrate so that a magnetic field produced by it exerts a magnetic attraction force directed from the carrier towards the substrate on the one of the components, at least during the transfer of the component, wherein the attraction force at least supports a placement of the component onto the place predetermined for the one of the components on the substrate, characterized in that the detachment unit for detaching the components from the carrier is a laser that is controllable in its intensity,a mirror arrangement of one or more movable mirrors and at least one mirror positioning actuator, wherein the mirror positioning actuator is configured to move and/or to swivel at least a single mirror of the mirror arrangement to reflect an emitted laser beam of the detachment unit, andat least one programmable control unit with a memory function that is configured to control the first actuator and the second actuator, and/or to control each mirror positioning actuator of the mirror arrangement independently of one another in each case.
