Patent ID: 8133823

Claim:
A method for picking up semiconductor chips provided on a wafer table, in which a first camera detects the position of a provided semiconductor chip and a chip gripper held on a bonding head picks up the semiconductor chip, with the bonding head with the chip gripper being movable by means of a pick system according to a system of coordinates KS immanent to the pick system, the method comprising in a setup phase performing an adjustment of a first setpoint position of the bonding head, said first setpoint position located in the visual field of the first camera, the adjustment including moving the bonding head to the first setpoint position, and determining and storing the coordinates of the first setpoint position relating to the system of coordinates KS and the coordinates of the first setpoint position relating to a system of coordinates KS 1 of the first camera, and in a production phase performing a readjustment of the first setpoint position at the occurrence of a predetermined event.
