Patent ID: 7069647

Claim:
A method for populating a substrate with electronic components, the method which comprises: providing a wafer holding frame with a perforated film clamped in the wafer holding frame and formed with passage openings arranged in individual rows and columns, and a plurality of electronic components of a semiconductor wafer separated into electronic components disposed under the passage openings of the film; providing a substrate with predetermined positions for placement of the electronic components; supplying the wafer holding frame into a positioning wafer holding device and supplying the substrate into a positioning substrate holding device and horizontally orienting the positioning wafer holding device and the positioning substrate holding device in an X direction and a Y direction relative to one another in a predetermined position for positioning a respective electronic component of the electronic components of the semiconductor wafer on the substrate; moving a vacuum forceps with a vacuum forceps holding device, while monitoring with a component position identification device, from a rest position vertically in a Z direction through a respective passage opening of the film while carrying along the electronic component, from a preliminary position, and carrying the electronic component into a mounting position on the substrate with rotation about the Z axis and fine adjustment of the vacuum forceps in the X direction and the Y direction.
