If you create your circuit board layout with the Target 3001 program from IB FRIEDRICH, please observe the following tips. Basically, it makes sense to use all the prescribed standard-layers of Target 3001.
We are happy to take care of generating the production data (Extended Gerber) for you. You just have to send us your *.t3001 file along with your order. All further steps are taken care of by our CAM engineers.
We naturally import your ODB++, Gerber-, KiCad-, OrCAD-, Target-, Eagle-, Altium-, IPC-2581-, DPF- and Sprint layout data free of charge!
Instead of the uncommon IPC-2581 format we recommend ODB ++ data!
Multi-CB parameters
For an optimal result, please define the free-of-charge high-tech parameters of Multi-CB:
- Track-width / space: 0.1mm (100µm) - free-of-charge ✓
- Annular ring: 0.1mm (100µm) - free-of-charge ✓
- Drills: 0.2mm (200µm) - free-of-charge ✓
- Via-Pad: 0.4mm (400µm) - free-of-charge ✓
This guarantees the best technology at the best price. The minimum possible values can be found here: Circuit board design parameters.
Standard layers
To convert your Target files, we use Target standard layers. Please specify any variations or extended layer specifications with your order.
| Layer type | Target name | Layer e.g. | Notes |
|---|---|---|---|
| TOP¹ | Copper top | 16 |  |
| BOT¹ | Copper bottom | 2 | |
| Inner layer 1¹ | Copper inside L2 | 10 | |
| Inner layer 2¹ | Copper inside L3 | 13 | |
| Inner layer #¹ | Copper inside L# | | |
| Vias² | Drill holes | 24 |  |
| PCB contour | PCB outline | 23 | |
| Scoring | 23 | ||
| Milling | Milling | 25 | |
| Solder-stop TOP | Solder stop mask top | 18 | |
| Solder-stop BOT | Solder stop mask bot | 4 | |
| Marking print TOP³ | Placement print top | 21 |  |
| Marking print BOT³ | Placement print bot | 7 |  |
| SMD Stencil TOP | Solder paste top | 19 | |
| SMD Stencil BOT | Solder paste bot | 5 |
1) Depending on how the layout data has been created, the option "with ground plane" will appear, please select it.
2) If NPTHs (Non-Plated-Through-Holes) are available, the option "Drill non plated extra" has to be checked.
3) Depending on how the layout data has been created, component names & values have to be integrated into this layer.
Gerber Export
If you want to make the Gerber export by yourself, you can normally use the default settings of Target. In the example image: 4 layer multilayer board.
Vias
You can choose the solder mask freely. Please note that when selecting 'completely covered with soldermask', vias > 300µm are not completely covered by the soldermask. See also Via Covering - Tenting.
Pad size
For "Soldermask +" you can enter a value of 0.050 mm (50 microns), this is the minimum tolerance for the soldermask not to be applied to the solder pad. The value should not be
(much) larger as well, so that fine-pitch components have still a solder mask bridge between the pads. If in doubt please simply leave 0.000 mm, the value is then optimized in the pre-production of our CAM station!
Checking of Gerberdata
In addition to our free import service for your data, you can also export your own Gerber data. Please use Gerber RS-274X.
Your exported Gerber files can be checked and printed with the freeware Gerbv or GC PREVUE. This allows testing if everything was exported correctly.
Gerbv and GC PREVUE can be found on our download page.
