Why is it necessary to convert PCB files into GERBER files and drill data to PCB manufacturing board?
Most engineers are used to sending the PCB files directly to the PCB factory after they are designed. However, the internationally popular method is to convert the PCB files into GERBER files and send the data to the PCB factory after drilling.
Because electronic engineers and understanding of PCB, PCB engineers from PCB factory of GERBER file may not be what you want, as you will be in the design of the parameters of the components 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.You can avoid this by converting your PCB files to GERBER files yourself.
GERBER file is a kind of international standard optical drawing format file, which contains rs-274-d and rs-274-x. Among them, rs-274-d is called basic GERBER format, and a d-code file should be accompanied to fully describe a graph.The rs-274-x is called the extended GERBER format and contains the D code information itself.Common CAD software can generate these two format files.
How do I check the correctness of the generated GERBER?You can simply import these GERBER files and D code files in free software Viewmate V6.3 to see them on the screen or print them out via a printer.
Drilling data can also be produced by various CAD software. The general format is Excellon, which can also be displayed in Viewmate.Of course you can't make a PCB without drilling data.
