PCB readme file

All files have the same project file name.  The file extensions indicate the contents of the file.  This list shows all possible file extensions.  Not all file extension types are included with each project.  All Gerber files are in RS274X format with 2:3 resolution in inches.  All files were produced with Altium Designer 6 software.  Note that a number of other files may be present in the .ZIP file.  These are additional text files generated by the CAM package which are not required for board fabrication.

If this PCB shows unplated holes and is being submitted for prototype rather than production, all holes may be plated if unplated holes are not supported.
