Abstract: An assembly device, in particular a fully automatic assembly device for producing microsystem technical products and for assembling components in the semiconductor industries, comprising an assembly table, a material transport system that transports the products to be placed with components, at least one transport system mounted on the assembly table, and at least one movable component transport unit with at least one assembly head. The component transport unit(s) is/are arranged on one or more carrier system(s) displaceable by means of a transport system in parallel to the direction of transport of the products to be placed with components, which products are in turn displaced by the material transport system(s).
