4.2 Mask data detail setting

Mask check positions

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

positions. You can specify positions on the mask where you want make a visual check after solder printing. Pressing the

[Edit] button at the upper right opens the "Manual Mask Check" dialog box. Set whether to use this function or not. Also

set the board interval (number of boards) at which to make the visual check.

Lighting setup for visual mask check

The lighting settings needed when making the mask aperture inspection (clogging inspection) and mask backside

inspection (inspection of excess solder spreading to backside) can be now separately set for each inspection and stored

as board data.

Pressing the [Teach] button after entering the mask inspection coordinates makes the following "Teach/Trace" window

appear. To set the lighting for the mask aperture clogging inspection, press the [Light] button while the [Aperture] button

is depressed. The lighting setup window then opens so you can change to a lighting level where you can easily check for

mask aperture clogging.

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.
