in the electronics industry, as far as file processing, most engineers are used to built in the PCB file sent directly to the PCB factory processing, and relatively popular in the international practice is to PCB file is converted into a GERBER file and drilling data after the coma to circuit board factory, why 'redundant'?
Because electronic engineers and understanding of PCB, PCB engineers from PCB factory of GERBER file may not be what you want, if you put the component when designing PCB drawing parameters are defined in the PCB file, you don't want to let these parameters showed on the PCB products, you not, PCB factory to all these parameters in the gourd painting gourd ladle on the PCB on the finished product.
This is just one example.
If you convert PCB file into GERBER file to avoid such events.
GERBER file is an international standard light painting format file, it includes RS -
D - and RS
X both formats, including RS -
D called basic GERBER format, and at the same time with the D code files can complete description a graphics;
X is called extension GERBER format, it itself contains a D code information.
Commonly used CAD software can generate the two format files.
Drilling data can also be produced by a variety of CAD software, the general format for Excellon;
No drilling data of course do not out of PCB.
