Patent ID: 7341877

Claim:
A calibration method in a chip mounting device, comprising the steps of: recognizing a first recognition mark and a second recognition mark to acquire a prescribed control parameter in a state where first recognition means and second recognition means have been moved into between a head, having a function to hold a chip, and provided with the first recognized mark and a stage, disposed below the head, having a function to hold a substrate, and provided with the second recognition mark, the first recognition mark being recognized by the first recognition means and the second recognition mark being recognized by the second recognition means when the first recognition means and the second recognition means are positioned between the head and the stage; recognizing both of the first recognition mark and the second recognition mark with third recognition means to acquire a prescribed control parameter in a state where the first recognition mark and the second recognition mark are close to or in contact with each other, obtained by moving the head toward the stage side; and correcting and updating a control parameter of a recognition means movement control system based on the prescribed control parameters.
