Abstract
A screen printing method and apparatus for applying paste into pattern apertures of a mask plate by sliding a filling member provided at a lower end of a squeegee head. The filling member forms an acute angle with an upper surface of the mask plate. Any extra paste on the mask plate is wiped by sliding a wiper provided at a lower end of the squeegee head. The wiper forms an obtuse angle with the upper surface of the mask plate.
Claims11
A method of screen printing for printing a paste onto a substrate via a pattern aperture formed in a mask plate by sliding a squeegee head on the mask plate, said squeegee head having a member defining a space for accommodating the paste, said method comprising the steps of:
- filling the paste into the pattern aperture by sliding a filling member provided at a first lower end of said squeegee head, said filling member forming an acute angle with an upper surface of the mask plate within said space;
- and
- removing extra paste from the upper surface of the mask plate by sliding a wiper provided at a second lower end of said squeegee head, said wiper forming an obtuse angle with the upper surface of the mask plate within said space.
A method of screen printing for printing a paste onto a substrate via a pattern aperture formed in a mask plate by sliding a squeegee head on the mask plate, said squeegee head having a member defining a space for accommodating the paste, said method comprising the steps of:
- applying a first pressure to the paste accommodated in said space when said squeegee head is in a waiting position;
- and
- applying a second pressure smaller than said first pressure to the paste accommodated in said space while said squeegee head is sliding on the mask plate for printing.
