What are the post-processing process and work steps of PCB board design?
The post-processing work of PCB board design is very much and very complicated. So, what are the post-processing process and work steps of PCB board design?
1. DRC inspection: that is, design rule inspection, through inspection methods such as Checklist and Report, focusing on avoiding major design defects such as open circuits and short circuits, and follow the PCB design quality control process and methods during inspection.
2. DFM inspection: After the PCB design is completed, whether it is the processing of the bare PCB board or the patch assembly processing of the PCBA support board, it is necessary to check the processing-related design with the help of related 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 during the design phase.
4. Silk screen adjustment: The clear and accurate silk screen design can improve the convenience and accuracy of subsequent testing, assembly and processing of the circuit board.
5. Marking on the Drill layer: The information marked on the Drill layer is a drawing of the processing requirements provided to the PCB processing factory for PE, which needs to follow industry specifications to ensure the accuracy and completeness of the drill processing information.
6. PCB design file output: The final file of PCB designneeds to be output as different types of packaging files in accordance with the specifications for subsequent testing, processing, and assembly.
7, CAM350 inspection: PCB design output to the CAM file of the PCB processing factory, you need to use CAM350 software for design review before boarding.
The above is the content of the post-processing process and working steps of PCB board design, do you know?
