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.

Aligning the board and mask positions

When the board and mask each have positioning marks on both sides, the following two positioning methods can be

used.

Mask mark

N Board and mask mark positions are on the same coordinates

N Board and mask mark positions are on different coordinates

Board mark

Positioning marks on Board and mask

Image processing is first performed to detect

the amount of position shift with reference to

the theoretical mark positions on the Board and mask.

Based on this, the Board and mask positions

are determined so that their marks are exactly aligned.

Based on this, the Board and mask positions are

determined so that their centers are exactly aligned.

Then, angular positioning of the Board and mask is

corrected respectively, so that a line connecting

the two marks is aligned with the line connecting

the theoretical positions of the marks.

5. Squeegee data setting

The following parameter items can be checked and edited on the [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 40 to 65 degrees. (Default setting is 55 degrees.)
