Creating and setting the data

To set the lighting for inspecting excess solder and flux spreading to the backside of the mask, press the [Light] button

while the [Surface] button is depressed. You can then change to an optimum lighting level on the lighting setup window.

In either case, closing the window automatically stores the changes you made into the board data.

NOTE

By storing the visual check lighting levels for the mask aperture and backside, you can switch to each lighting level by

just pressing the [Aperture] button for the mask aperture visual check or the [Surface] button for the mask backside

visual check.

Mask aperture (hole) coordinates setting

When you press the [Detail] button on the [Print]-[Mask] tab, the following dialog box appears for setting the mask

aperture coordinates.

This function is available only for machines equipped with an optional print inspection camera.

For details, see "2.3 Using the mask scan function" in the separate Option Manual.

5. Squeegee data setting

The following parameter items can be checked and edited on the [Print]-[Squeegee] tab.

[Print]-[Squeegee] tab

1: Squeegee Type

Select "3S Head” when using the 3S squeegee head. When using an optional double squeegee, select "Double Squeegee".

TIP

The squeegee type has been set in the machine data prior to shipment according to the machine speciﬁcations. So

the same squeegee type as set in the machine data must be selected here. If not the same squeegee type, an error

is issued.

E: Solder Name

Enter the name or comment on the solder to be used. You can leave this field blank.

i: Squeeges Name

Enter the name or comment on the squeeges to be used. You can leave this field blank.

A: Squeegee Detail Type

Specify the squeegee type and size when the squeegee type is set to "3S Head” or “Double Squeegee".

B: Attack Angle (deg.)

This parameter is available only when the squeegee type is set to "3S Head". (This parameter does not appear when the

squeegee type is set to "Double Squeegee".)

Set the angle formed between the 3S squeegee scraper and the mask surface in order to print solder most efficiently. The

setting range is from 45 to 65 degrees. (Default setting is 55 degrees.)

C: One Way/Round

Select whether to print solder in one direction or in both directions.

D: F. & B. Print Condition

Select whether to use the same conditions for the forward and backward printing. When this parameter is set to "Same

Condition", the forward and backward printing operations are performed under the conditions specified for the "F.

Squeegee Speed" and "F. Squeegee Force", and the settings for the "B. Squeegee Speed" and "B. Squeegee Force" are

disabled.

E, G: F. Squeegee Speed (mm/sec), B. Squeegee Speed (mm/sec)

Set the forward and backward squeegee movement speeds to print solder. Find an optimum speed while checking the

scraped state of the solder on the mask. If this speed is too fast, the squeegee may not scrape solder properly. If too slow,

solder may spread into the backside of the mask.

F, H: F. Squeegee Force (N), B. Squeegee Force (N)

Set the pressure (force) to apply a load to the squeegee during printing in the forward and backward directions. Check

the scraped state of the solder on the mask to find an optimum squeegee pressure. Set this pressure at a lower pressure as

long as the solder is scraped properly. A larger squeegee pressure is required as the squeegee speed is set faster.

J: Solder Supply Interval (Board)

Set the number of boards to be printed per one supply of solder, based on the amounts of solder supplied and used

during printing.

I: Squeegee Pressure Check Type

This is the setting whether to check the print pressure measured while printing. If the print pressure is out of the specified

threshold while printing, the board is carried to the position where the board is taken out, then the error stops the

machine.

• Not Use

This function is not activated.

• Average

If the average value of the print pressure exceeds the threshold, the error stops the machine.

• Max / Min

If the momentary value of the print pressure exceeds the threshold, the error stops the machine.
