Use of placeable marker components for a staged placement of components on a carrier

A placement machine for the placement of electronic components on a carrier, in particular for the placement of unhoused, electronic components on the carrier for the purposes of producing housed electronic components, the placement machine comprising:

• a chassis;
• a transport device for transferring the carrier along a transport direction from a first spatial location into a second spatial location, wherein a first section of the carrier is allocated to the first location for a first placement content and a second section of the carrier is allocated to the second spatial location for a second placement content;
• a gantry system with a stationary component, which is mounted in a stationary manner to the chassis, and with a moveable component, which can be positioned relative to the stationary component;
• a placement head, which is mounted on the moveable component and which is configured to pick up components and marker components and after a suitable positioning of the moveable component equip the carrier with the components at predefined placement positions and place the marker components on the carrier in an overlap area of the carrier;
• a camera for the first optical detection of first positions of the placed marker components, when the carrier is located in the first spatial location, and for the second optical detection of second positions of the placed marker components, when the carrier is located in the second spatial location;
• and
• a control unit for controlling at least the operation of the placement head, wherein the control unit is configured such that the spatial locations of the placement positions within the second section depend on the result at least of the second optical detection of the placed marker components.
