Convert DDB to PCB

Understanding DDB and PCB file formats

DDB files are Database files used by Protel (now Altium Designer), an electronic design automation (EDA) software. These files store entire PCB projects, including schematics, layouts, libraries, and related data, in a single database container.

PCB files, on the other hand, are Printed Circuit Board layout files. They contain the actual board design, including component placement, routing, and layers, and are used for manufacturing or further editing in various EDA tools.

Why convert DDB to PCB?

Converting a DDB file to a PCB file is often necessary when you want to extract just the board layout from a Protel project for use in other EDA tools or for manufacturing purposes. PCB files are more widely supported and easier to share or modify independently of the full project database.

How to convert DDB to PCB

The most reliable way to convert a DDB file to a PCB file is by using Altium Designer or older versions of Protel. Here’s how you can do it:

1. Open your DDB file in Altium Designer or Protel 99 SE.
2. In the project tree, locate the PCB layout within the DDB (usually listed as a .Pcb document).
3. Right-click the PCB document and select Save As or Export.
4. Choose the PCB file format (typically *.Pcb or *.PcbDoc).
5. Save the file to your desired location.

If you do not have access to Altium Designer or Protel, you may try using Altium Designer Viewer to open the DDB and export the PCB, but editing and export options may be limited.

Recommended software for DDB to PCB conversion

• Altium Designer – The most comprehensive and reliable tool for opening and exporting DDB files to PCB format.
• Protel 99 SE – Legacy software that natively supports DDB files and can export PCB layouts.
• Altium Designer Viewer – Free viewer for opening DDB files, though export capabilities are limited.

Tips and considerations

• Always back up your original DDB file before conversion.
• Check the exported PCB file for completeness and accuracy, as some data may not transfer perfectly.
• If you need to use the PCB file in another EDA tool, consider exporting to industry-standard formats like Gerber or ODB++ after conversion.
