POSITION MATCHING METHOD AND SCREEN PRINTING DEVICE

Title:

POSITION MATCHING METHOD AND SCREEN PRINTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2008/007744

Kind Code:

A1

Abstract:

A printing device includes a mask sheet (25), a movable printing stage (3), a camera head (40) having a mask recognition camera (41) and a substrate recognition camera (42), and a controller for controlling them. The controller executes mark recognition of the substrate (W) by using the substrate recognition camera (42). The camera head (40) is driven/controlled so as to execute mask recognition of the mask sheet (25) periodically by using the recognition camera (41) while the same mask sheet is used. Moreover, according to the latest mask position information acquired by the mark recognition of the mask sheet (25) and the substrate position information, the controller obtains a correction amount based on the position shift between the mask sheet (25) and the substrate (W) and drives/controls the printing state (3) according to the correction amount so as to mount the substrate (W) on the mask sheet (25).
