ABSTRACT:
An apparatus for mounting semiconductors contains a bonding station, whereby the bonding station comprises a wafer table for presenting the semiconductor chips, a substrate table and a pick and place system with a bondhead with a chip gripper. Part of the wafer table is located underneath the substrate table. The pick and place system has a first linear motor that comprises a rigidly arranged stator and a shuttle that can be moved in a first direction guided by first guide elements, and a second linear motor that comprises a rigidly arranged stator and a shuttle that can be moved in a second direction. The shuttle of the first linear motor has second guide elements that guide the shuttle of the second linear motor. The bondhead with the chip gripper is arranged on the shuttle of the second linear motor.
