SCREEN PRINTING MACHINE AND ELECTRONIC COMPONENT MOUNTING SYSTEM

摘要

A screen printing machine for forming a print of paste supplied to a mask plate having pattern holes, includes: a filling squeegee which is held to have a given clearance with respect to the mask plate, and which fills the pattern holes with the paste by moving the filling squeegee relative to the mask plate in a printing direction; and an urging member which urges the filling squeegee toward the mask plate such that at least the given clearance is maintained. The screen printing machine further includes a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction, and which scraps off paste remaining on the mask plate after passage of the filling squeegee by moving the scraping squeegee together with the filling squeegee in the printing direction.
