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 is 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 motor which sucks air through the blower suction pipe to generate a blower suction force in the first suction hole; and an inverter which changes frequencies of the motor.

First claim

What is claimed is:

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 provided with a first suction hole and a second suction hole and allowed to contact a lower surface of the board;
a blower suction pipe communicating with an internal space of the box-like member and extending to an outside of the box-like member;
a vacuum suction pipe connected to the second suction hole provided in the top-plate portion of the box-like member and extending to the outside of the box-like member through the internal space of the box-like member;
a motor configured to suck air through the blower suction pipe to generate a blower suction force in the first suction hole; and
an inverter configured to change frequencies of the motor.

2. The screen printing apparatus according to claim 1 , further comprising an operation panel configured to adjust frequencies of the motor through the inverter.

3. The screen printing apparatus according to claim 1 , further comprising
a vacuum pressure supplying device configured to supply a vacuum pressure to the second suction hole through the vacuum suction pipe.
