Screen printer and screen printing method

Abstract

To provide a screen printer and a screen printing method that can assure a required degree of accuracy of print position when a type of work requiring a high degree of positional accuracy is taken as a target. In relation to screen printing of a plurality of single-piece substrates 11 held on a carrier 10, a cavity portion 15 having print patterns assigned to the respective single-piece substrates 11 are provided on a mask plate 14, and a camera head unit 23 captures an image of the mask plate 14 and the single-piece substrates 11, to thus recognize the position of the mask plate and the positions of the respective single-piece substrates. The single-piece substrates 11 held by the carrier 10 are individually positioned to the cavity portion 15 and sequentially printed according to a result of recognition. It is thereby possible to eliminate a chance of occurrence of a positional error, which would otherwise be caused by variations in positions of the respective single-piece substrates 11 when the plurality of single-piece substrates 11 are positioned to the mask plate 14 by one operation.
