Board outlines are shown for reference only. Board fiducials and board

badmarks are depicted according to the pattern that they appear on the

panel. The File > Group Mode command has a check mark next to it indi

cating the activation of Group Mode. Selecting this command again will exit

group mode and remove the check box. No editing operations other than

Group functions will be allowed while in Group Mode. The usual querying and

viewing operations are available.

■ Create New Group (Fiducial/Reject): Forms a fiducial or badmark

(Reject) group from the selected items, depending on which type of items

are currently selected. Illegal combinations are rejected. For example, only

a single panel-level badmark may be included in a badmark group.

Including a board-level mark or two panel-level marks would be rejected.

■ Delete Group: Deletes the currently selected Group(s).

■ Select Group Items: Selects all items on the currently selected Group(s).

■ Add To Group: Adds selected items to currently selected Group. Only

additions resulting in a legal group are permitted.

■ Delete From Group: Deletes selected items from currently selected group.

If the result would contain no board instances, no fiducials (in a fiducial

group), or no badmarks (in a badmark group) then the selected group

itself is deleted in its entirety.

Additionally, the InfoParts command will (in group mode) indicate the

number of groups of each kind that a board instance in included. That is, for

step-and-repeat marks, the InfoParts command will show how many fiducial

and badmarks a step-and-repeat mark is included in.

Step-and-repeat marks will be displayed by colour depending upon their

inclusion in fiducial or reject groups.

■ Red will indicate inclusion in neither kind of group.

■ Green will indicate inclusion in both kinds of groups.

■ Yellow will indicate inclusion in only one kind of group.

Fiducial and badmark groups will be shown by a dotted line connecting all of

the grouped items

(see FIGURE 8 on page 54). The finely dotted lines will be

coloured white and represent a fiducial arrangement. The coarsely dashed

lines will be coloured blue and represent a badmark group.

2.18 Set Fiducial Arrangement

The following paragraph describes how fiducial arrangements are set using the

MDF editor. The Fiducial arrangement uses the same fiducials for the

alignment of several circuits. For example

see SCREEN 33 on page 55, PCB has

‘n’ step and repeat circuits with fiducials.
