We begin choose PCB manufacturer after a PCB be finished layout. What jobs do we need to do before we choose the factory?
1. Outputs gerber file and drilling file
Some engineer designed the PCB files and sent them to the PCB board factory directly. The PCB board factory has to transform the Gerber files on its own. Some companies require the conversion of PCB files to GERBER and drilled files to PCB factory. Because PCB engineers do not understand the functions and applications of electronic components, they will only produce according to the information provided by PCB. Maybe the GERBER file transferred from PCB factory is not what you want.
If the parameters of the components are defined in the PCB file at the time of design, they do not want these parameters to be displayed on the PCB finished products. If not specifically explained, the PCB factory engineers output these parameters to Gerber, this information will remain on the PCB finished product. Some engineers like to design metallized slot in the outline layer. If PCB spec instructions are not provided, PCB engineers may make the slot non metallized. If you convert your PCB files to GERBER files, you can avoid such incidents.
The GERBER file is an international standard drawing format file, which contains two formats of RS-274-D and RS-274-X, in which RS-274-D is called the basic GERBER format, and a D code file can be incidentally attached to a complete description of a graph. RS-274-X is called extended GERBER format, which contains D code information in itself. Commonly used CAD software can generate these two format files. Now it is generally required to produce GERBER files to the board plant in RS-274-X format.
How do you check the generated GERBER correctness? You can use the CAM350 software to import these GERBER files and D code files, you can see them on the screen or print them through the printer, then confirm them.
