Abstract

See full text

The present invention relates to a method of correcting a position of a stencil mask which comprises receiving fiducial information from a screen printer, extracting position information of a pad and position information of a solder formed on a board through measuring by a solder paste inspection apparatus, estimating an x, y offset value and a rotating amount of a stencil mask based on the fiducial information by using the position information of the pad and the solder, and transmitting the x,y offset value and the rotating amount of the stencil mask to the screen printer. Thus, a reliability of solder forming process may be increased by correcting a stencil mask position by transmitting a feedback of an x,y offset value and a rotating amount of the stencil mask from a solder paste inspection apparatus, in which the x,y offset value and the rotating amount are estimated based on fiducial information transmitted from the screen printer.
