1. A placement system for populating a substrate with at least one electronic component of a semiconductor wafer divided into electronic components, the placement system comprising:
a substrate holding device for receiving the substrate;
a wafer holding device disposed above said substrate holding device and adapted to receive a wafer holding frame;
said substrate holding device and said wafer holding device being disposed to be positioned with respect to one another horizontally in an X direction and a Y direction;
a vacuum forceps holding device disposed above said wafer holding device, said vacuum forceps holding device having a vacuum forceps, which can be finely adjusted in the X direction and the Y direction with regard to said substrate holding device and disposed to be rotatable and finely adjustable about a Z axis extending in a Z direction; and
said vacuum forceps holding device being configured to move said vacuum forceps, in a region of said wafer holding frame, vertically in the Z direction into a rest position, into a preliminary position, and into a mounting position.
