Abstract

In a screen printing apparatus, a squeegee is slid on a mask contacting a board to print paste onto the board via pattern holes formed in the mask. The screen printing apparatus includes: a box-like member including a top-plate portion in which first suction hole and a second section hole are formed and which is allowed to contact the board; a blower suction pipe communicating with an internal space of the box-like member and extending outside the box-like member; a blower suction source sucking air through the blower suction pipe to generate a blower suction force in the first suction hole; a vacuum suction pipe connected to the second suction hole and extending through the internal space to an outside of the box-like member; and a vacuum pressure supplying device supplying a vacuum pressure to the second suction hole through the vacuum suction pipe.

Claims

1. A screen printing apparatus in which a squeegee is slid on a mask contacting a board to print paste onto the board via pattern holes formed in the mask, said screen printing apparatus comprising:

a box-like member comprising a top-plate portion in which first suction hole and a second section hole are formed and which is allowed to contact a lower surface of the board;

a blower suction pipe which communicates with an internal space of the box-like member, and which extends outside the box-like member;

a blower suction source which sucks air through the blower suction pipe to generate a blower suction force in the first suction hole;

a vacuum suction pipe which is connected to the second suction hole, and which extends through the internal space of the box-like member to an outside of the box-like member; and

a vacuum pressure supplying device which supplies a vacuum pressure to the second suction hole through the vacuum suction pipe.

2. The screen printing apparatus according to claim 1, wherein the box-like member is replaceable.

3. The screen printing apparatus according to claim 1, wherein the top-plate portion of the box-like member is replaceable.
