ABSTRACT:
Disclosed is a method for assembling cassette-loaded microcomponents, requiring only a small number of component-specific ejector tools and capable of being implemented more quickly. According to the inventive method, at least two cassettes provided with component carriers are used, whereby each cassette has at least one type of component and the positions of the components are adapted to each other. At least one cassette acts as a base plate cassette wherein the microcomponents are arranged on a base plate acting as a component carrier. At least one joint assembly step is carried out, wherein two cassettes are respectively placed opposite each other and all microcomponents in the joined cassettes are simultaneously assembled to form sub-assemblies or component units. The component carriers of the cassettes are subsequently withdrawn. During assembly, the microcomponents can also be held in a rotationally secure position. The invention also relates to an assembly device for assembling cassette-loaded microcomponents.
