The invention relates to an apparatus for mounting components on a substrate. The apparatus comprises a bond head with a component gripper, a first drive system for moving a carrier over relatively long distances, a second drive system which is attached to the carrier for moving the bond head back and forth between a nominal working position and a stand-by position, a drive attached to the bond head for rotating the component gripper or a rotary drive for rotating the substrate about an axis, at least one substrate camera attached to the carrier and at least one component camera. At least one reference mark is attached to the bond head or the component gripper.

The invention relates to an apparatus and a method for mounting components on a substrate. The apparatus comprises a bond head with a component gripper, a first drive system for moving a carrier over relatively long distances, a second drive system which is attached to the carrier for moving the bond head back and forth between a nominal working position and a stand-by position, a drive attached to the bond head for rotating the component gripper or a rotary drive for rotating the substrate about an axis, at least one substrate camera attached to the carrier and at least one component camera.

At least one reference mark is attached to the bond head or the component gripper.

An apparatus for mounting components on a substrate comprises a pick and place system with a bonding head, a camera and two optical deflection systems. The first optical deflection system and the camera form a first image detection system for recording an image of the substrate location on which the component is to be mounted. The first optical deflection system, the second optical deflection system and the camera form a second image detection system for recording an image of a bottom side of the component. The pick and place system moves the carriage from a take-up location of the component to the substrate location in a respective predetermined height Habove the second optical deflection system, so that the bottom side of the component is located in a focal plane of the camera, and lifts the carriage to a respective predetermined height H, so that the substrate location is situated in the focal plane of the camera.
