2. “Aperture”-File: Select appropriate aperture file that comes with the
Gerber data and that has the correct layout.
(see n "Creating the correct
aperture file" on page 113)
3. “View”-button: For each of the Layers in the Gerber data a “View”-button
is present that can be used to check what the result is for that specific
layer combination of gerber file and aperture file.
(see 3.3.4.3 "“PCB
Artwork” Window" on page 118)
4. “Rotation panel”-buttons: If the artwork is not shown correctly in the PCB
artwork window the artwork can be rotated to the Left or to the Right by
pushing these buttons. To see the artwork again the “View”-button must
be used to see the results. The rotation is done for all tree layers.
5. “Mirror panel”-frame: If the artwork is not shown correctly in the PCB
artwork window, the artwork can be mirrored by using the selections
“Mirror in vertical axis”, “Mirror in horizontal axis”.
6. “Crop panel”-frame: 4 sizes can be entered that define a panel size. By
entering these the artwork becomes smaller. The Artwork is cropped. By
using the “View”-button the results can be seen in the “PCB artwork”
window.
(see 3.3.4.3 "“PCB Artwork” Window" on page 118).
7. “Select panel size (mm)”-frame: After selecting the correct gerber and
aperture file a possible board size are calculated. In most cases the correct
panel size is selected but can be changed by using this ComboBox.
8. “Skip”-Button: If you can have products which are quite small (or a panel
with several boards) and these panel have several fiducials. These products
you can already optimize in LOCAL mode without having to use the
artwork extraction.
9. Single Circuit: In sole cases gerber files will be provided that represent one
circuit (board) of a multi-circuit PCB, enable this option to automatically
create the required number of circuits. If the gerber files visualize the
complete board, then disable this option.
NOTE: This means that over the PCB there must be enough fiducial so always 2
fiducials with a maximum difference in X direction of 75 mm are available.
If this is not the case an error is created and the option “Continue”-Button
must be used meaning that artwork extraction (Gerber) must be done.
10. “Next”-Button: After the PCB Artwork window shows the correct graphical
presentation of the files this button can be selected and the artwork
extraction continues with the next step.
(see 3.3.4.4 "Aligning artwork
with Cad-data" on page 118)

NOTE: As in CAD data also the artwork must be rotated in such a way as the panel
goes through the machines. So both MDF as well as artwork must be rotated
under the same angle.

3.3.4.4 Aligning artwork with Cad-data
Step two from the pre-optimizing stage for Local mode is the alignment of the
extracted artwork from the Gerber data and the CAD data (MDF).

SCREEN 69 Step2 Aligning artwork with Cad data
This step is to align the MDF data with the Artwork data from the Gerber files.
The MDF data and the PSI information is used to obtain the correct size of the
components on the board. These will be shown as black boxes in the graphical
presentation
(see SCREEN 70 "Unaligned Artwork with Cad data" on page
119).
SCREEN 70 Unaligned Artwork with Cad data
The first action in this stage is to use the “Automatic”-button. After pressing
the “Automatic”-button in the “Preprocessing PCB data”-window a new
window pops up
(see SCREEN 72 "Aligned Artwork with board data" on page
121). By shifting the mouse until the circle with cross is on the correct
fiducial (see SCREEN 71 "Matching gerber with fiducial after alignment" on
page 120) and automatically all components (black boxes) are on the correct
