4.1.1 Replacement of Squeegee

When the squeegee edge is worn out or deformed by solvent, etc., replace

the squeegee with a new one to avoid any hindrance in printing.

• Loosen the squeegee anchor bolts and detach the squeegee.

• Attach a new squeegee as shown in Fig. 4A54 and tighten the anchor

bolts. At this time, be sure to push Plane A

of the squeegee against the ﬂat

surface such as a surface plate and tighten the bolts evenly without any

warpage.

• After tightening the bolt, push the squeegee against a straight surface

such as a surface plate (edge portion) and conﬁrm that there is no

clearance.

Perform the adjustment while the squeegee angle is at 60° (ﬁxed) to the

surface plate.

Note

It is recommended that Plane A should be ground to secure the straightness

with the squeegee being attached for good printing quality.

Especially, the squeegee with its straightness being well maintained

works effectively for ﬁnely-pitched pattern printing and accurate

coating (thickness) of paste.

(2) Adjust the pushing distance by changing Dimension L (the distance

between the upper end plane of the ball bushing and the lower end

plane of the stopper nut).

The pushing distance of the squeegee against the screen is set to "1.0

mm". (Factory-Adjusted upon Shipment)

When the stopper nut is turned once clockwise, the pushing

distance becomes shorter by 1.0 mm. Turning the stopper nut once

counterclockwise makes the pushing distance longer by 1.0 mm.

Pushing Distances Dimension L during Upward

Movement of Cylinder

0.5 mm 57.0 (58.5) mm

1.0 mm 57.5 (59.0) mm (Standard Setting)

1.5 mm 58.0 (59.5) mm

The values in ( ) are applied when metal squeegees are used.

(3) Use the "Print Block" tab sheet to push the squeegees against the PCB

located at the printing position. (Operation Sequence: [MAINT.] Button

→ [MAN. SUB-SYS] Button → "Print Block" Tab)

Refer to the above table and check the relation between Dimension L

and the pushing distances.
