Device for introducing electric components into continuous tapes

Abstract

The invention relates to a novel device for introducing (packaging) electric components that are punched out of a lead-frame into/in recesses or pockets of at least one tape that are made available at an insertion position. The insertion process is carried out using at least one component holder that can be displaced between a removal position and the insertion position.
