The invention relates to a transmission route for transmitting a plane charging box of a circuit board transmission system with a plurality of transmission routes, providing a device (110) equipped with a plurality of elements for a component carrier (102), comprising: a first transmission route (121), for transmitting a first component carrier (102) to a first assembly area (122); a second transmission route (131), for transmitting a second component carrier (132) to a second assembly area; an assembly head (136), moving in such a way, namely reaching at least two assembly areas (122, 132), wherein the second transmission route (131, 231) is arranged is such a way, namely the element stored in the plane charging box (104) can be transmitted to the second assembly area (132). Also provided is an assembly system (100) for assembling elements for the component carrier (102), with at least an assembly device (110). Also provided is a method for assembling the elements for the component carrier (102), wherein the element is stored in the plane charging box (104). The assembling device (110) is used hereon.
