| Artwork Scanning |
NPI offers a complete scanning service to convert film art works, paper art works or a raw board into standard CAD data including full intelligence for netlist and assembly programs. Image sizes up to 18 X 20 are standard. The price for scanning is based on size, quantity, quality of art work, and required turnaround time. |

| What is Scanning |
Scanning is the solution when CAD/CAM data has been lost or never existed, or when existing photo tools are unusable for fabrication. Scanning creates digital representations of hard copy photo tools for further processing of all CAD/CAM outputs. Once in CAD format the file can be edited to fix problems or produce new photo tools. |
| |
| When to use Scanning |
- Scanning is used to improve the quality of questionable photo tools.
- To create CAD data files for importation to CAM stations for panelization and design rule checks.
- To improve board quality and better yields due to correction of photo tool imperfections.
- To create NC drill and rout data for the printed wiring board manufactures.
|
| Considerations |
The quality of the photo tool has an effect on the cost of scanning. In general the better the photo tool the less the cost. The major concern is whether the photo tool was generated by a standard CAD program or laid up by hand. Standard pad, trace sizes and features arranged on a grid, greatly increase the efficiency of scanning. Silver Halide (black) film, diazo (brown) film, paper and even raw boards may be scanned to produce accurate CAM data. Clean film without scratches require less modification than old, dirty and scratched films. Whether the film is a positive or negative is not a concern for scanning. Due to the many attributes of art masters, a more accurate final quote may be given after these art masters are reviewed.

| Artwork Editing |
NPI provides an editing service for the modification of CAD files.
Editing may be as simple as step and repeat of circuit patterns to the modification of trace, component and pad locations.
Cost is determined by the magnitude of the modification.
All modifications are done at $100.00 per hour with a minimum of $25.00. |
| |
| What is Editing? |
Editing is the addition, removal or modification of features of the photo tool. For example unwanted pads may be removed from the photo tools, existing features like traces may have the width increased or reduced. The Art work may be compensated to the requirements of the fabricator's process parameters. " Comping " refers to making global adjustment in length, width and alignment of the photo tool. In a nut shell, editing fixes or compensates for problems. This is done to increase quality, yields and productivity. |
| |
| When to use Editing |
| You should consider editing when there are simple errors in the routing of circuitry or when there is problems with the alignment of layers in the design. If there are extra features, unwanted features or missing features, editing will make sense. Layer to layer shorting of dead end vias may easily be fixed. As long as the scope of the problems are relatively small, editing is the answer. Problems of larger scope may require redesign |
| |
| Considerations |
The main concern is the scope of the changes and the availability of CAD data. Large edits are not cost effective, it is then better to redesign the board. If there are no CAD files then the art work will need to be scanned, converted to a standard CAD format and then edited. |
