Abstract

An assembly system and a method are for assembling components on substrates. The system includes a transport track and several substrate carriers that can be displaced, for example, perpendicularly to the transport track. The substrate carriers can be loaded with substrates using loading that can be displaced in the direction of transport. Manipulation devices for removing components from feed devices and depositing the components on the substrates are arranged next to the transport track, so that they can be displaced laterally in the direction of transport. The feed devices can be displaced in a substantially perpendicular manner in relation to the direction of transport, in order to align the pick-up point for the respective components along a single pick-up track, parallel to the transport track.
