Abstract

In a device and a method for aligning and holding a plurality of singulated semi-conductor components in receiving pockets of a terminal carrier that are separated from each other, the terminal carrier has spring elements, which are part of a spring plate. The spring plate has a plurality of recesses disposed next to each other for forming a corresponding plurality of receiving pockets for the semi-conductor components, wherein the spring elements are formed from the spring plate in one piece.
