The post-processing work of PCB board design is very much and very complicated. So, what are the post-processing processes and working steps of PCB board design?
1. DRC inspection: design rule inspection, through Checklist and Report and other inspection methods, focus on avoiding major design defects such as open circuit and short circuit, and follow the PCB design quality control process and method at the same time.
2. DFM inspection: After the PCB design is completed, whether it is the processing of the PCB bare board or the patch assembly processing of the PCBA support board, it is necessary to check the processing-related design with the help of relevant inspection tool software or Checklist.
3. ICT design: Some PCB boards will undergo ICT testing in batch processing and production. Such PCB boards need to add ICT test points in the design stage.
4. Screen printing adjustment: Clear and accurate silk screen design can improve the convenience and accuracy of subsequent testing, assembly and processing of circuit boards.
5. Marking on the Drill layer: The information marked on the Drill layer is the processing requirement drawing provided to the PCB processing factory PE, and it is necessary to follow the industry norms to ensure the accuracy and completeness of the Drill processing information.
6. Output of PCB design file: The final file of PCB design needs to be output as different types of packaged files according to the specifications for subsequent testing, processing, and assembly.
7. CAM350 inspection: The CAM file output from the PCB design to the PCB processing factory needs to use the CAM350 software for design review before boarding.
