To avoid further inquiries and thus unpleasant disturbances for you complete and clear data are necessary.

In the following we arranged some information to the different data formats for you.

Eagle

The Eagle CAD Software has a modul to export PCB datas. There is a configuration for the export of the different design- and mechanical-layers.

If we don’t get any further information with your order we use the following setting.

Eagle is using among other things octogonal pads which can lead to a false interpretation in other systems. To avoid those difficulties we use round pads instead.

Target

We planned the Layer allocation list in the target System as follows. Please send us with your data expenditure information if there were differences.

The copper layer in Target always consists of three layers.
The layer copper contains the tracks.
The Layer area contains ground areas.
The Layer delete contains surfaces around the tracks (to check distances).

ODB++

ODB++ makes an optimized data exchange possible between Design and manufacturing.

It makes possible shorter turn-around times because all information for the printed circuit board for manufacturers are clearly defined.

It improves the quality by the avoidance of data exchange errors. By the clear definition no different interpretations are possible. Data formats with different dialects, like e.g. RS274X, can on different CAM systems cause different results. Thus substantial damage can develop.

With the expenditure of the layout data we get smaller data sets develop because filling of surfaces with vectors are avoided there.

ODB++ is a fully expandable ASCII data format with the following advantages:

  • All datas are included in one file. Nothing will be lost.
  • There is a exact description of the graphical datas. No unnecessary filling of copper areas or pads with special forms which has to be exchanged by the pcb manufacturer.
  • As many as desired attributes for the elements of the printed circuit board can assign to describe these elements.
  • ODB++ contains a CAD Netlist description on the basis those that Printed circuit board manufacturer can examine the electrical connections during the production process for their agreement with the original Design.
  • ODB++ contains a position table in that the layers names, the kinds of the layer the polarity as well as the sequence of the situations in the printed circuit board is defined.
  • A layer matrix that the parts list and the total structure of the plate defines.
  • ODB++ contains for the drill- and rout-layers the allocation which drill contact which layer.
  • Graphic notes can be attached according to the kind of a post it.

Gerber 274

The Gerber format was originally used for the control of photo plotters. There for between the exposure light and the photosensitive film an aperture is brought in which has different form and size depending of the requirements. Open and closing the shutter and moving the table the image is brought on the film. The photo plotters are today replaced by laser plotters.

The Gerber format is a variant of the conventional numerical control format. Of conventional Numerical control formats, like e.g. drilling data, it differs only by the selecting of d-codes. The data are arranged thereby in blocks what is a combination of the commands for the aperture selection, shutter mode (shutter open/close) and movement (X- Y-coordinates) The data are block-by-block processed.

For defining the apertures on the CAM-System an aperture list will be necessary which described the form and size of the apertures. This must be usually entered manually into the CAM-System. This represents a substantial expenditure for the printed circuit board manufacturer.

Example for an aperture file Example for a Gerber file

D12 round 8 X0000Y0000D02*
D13 square 4 X0000Y1000D02*

Drill Datas one File for PTH/NPTH/sequentiel PTH
Drill Diameter defined in the Fileheader
Format should be Excellon or Sieb & Meyer
Aperture Description please add the aperture table to the data record
the table should define the d-codes with form and size

Gerber 274x

The extended Gerber Format (RS274X) an extension of the standard Gerber Format. Contrary to the standard Gerber format an aperture list is not necessary list, since the aperture information is contained already in the data file.
