Squeegee unit and solder-paste printing machine

摘要

A squeegee unit comprises a paste pressurizing slope and a squeegee. The paste pressurizing slope is inclined at an angle narrower than 90° to a surface of a screen mask in a printing direction. As solder paste is pressurized by means of the paste pressurizing slope, the solder paste is filled into a mask hole. The squeegee has a paste scraping surface for scraping off the solder paste on the screen mask. The paste scraping surface extends at an angle of 90° or more to the surface of the screen mask in the printing direction.
