Abstract
In a screen printing that shifts squeegees in a horizontal direction while abutting the squeegees against a mask, and slides the squeegees on the mask, and scrapes up the paste on the mask so that opening portions are filled with the paste to transfer the paste onto the substrate, a larger amount of paste Ps is supplied to regions in which the paste is scraped up by the end portions of the squeegee than a region in which the paste is scraped up by a center portion of the squeegee on the mask.
Claims2
A screen printing machine, comprising:
- a mask that is brought into contact with a substrate;
- a squeegee shift control portion that shifts squeegees in a horizontal direction while abutting the squeegees against the mask brought into contact with the substrate, and slides the squeegees on the mask, and scrapes up the paste on the mask so that opening portions provided in the mask are filled with the paste to transfer the paste onto the substrate;
- and
- a paste supply portion that supplies a larger amount of paste to regions in which the paste is scraped up by end portions of the squeegee than a region in which the paste is scraped up by a center portion of the squeegee on the mask, before the paste is transferred onto the substrate by the squeegees.
A screen printing method, comprising:
- a mask contact step of bringing a mask into contact with a substrate;
- a paste transfer step of shifting squeegees in a horizontal direction while abutting the squeegees against the mask brought into contact with the substrate, and sliding the squeegees on the mask, and scraping up the paste on the mask so that opening portions provided in the mask are filled with the paste to transfer the paste onto the substrate;
- and
- a paste supply step of supplies a larger amount of the paste to regions in which the paste is scraped up by the end portions of the squeegee than a region in which the paste is scraped up by a center portion of the squeegee on the mask, before the paste transfer step is executed.
