Title:
METHOD FOR COMPENSATING SCREEN PRINTER, AND SUBSTRATE INSPECTION SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/162341
Kind Code:
A1
Abstract:
The present invention relates to a method for compensating a stencil mask of a screen printer, the method comprising the steps of: receiving fiducial information from a screen printer; extracting position information for a pad and a solder disposed on a substrate by means of measurements from a solder inspection equipment; estimating, using the position information of the pad and solder, the x and y offset values and amount of rotation of the stencil mask on the basis of the fiducial information; and transmitting the x and y offset values and the amount of rotation of the stencil mask to the screen printer. Thus, the solder inspection equipment estimates the x and y offset values and the rotation amount of the stencil mask on the basis of the fiducial information transmitted from the screen printer, and the location of the stencil mask is compensated by means of the estimated values fed back to the screen printer, thereby allowing the reliability of solder printing to be improved.
