Contents of PCB manufacturability design review

After the PCB design is completed, we need to perform functional checks on all projects. Just like when we finish the test paper, we need to do a simple analysis and inspection, and look at all the questions again to ensure that there will be no major mistakes due to negligence. Similarly, the PCB design is the same. The following are the inspection items that need to be carried out after PCB design:

1. DFM review of bare board: whether the production of bare board meets the process requirements of PCB manufacturing, including wire width, spacing, wiring, layout, vias, Mark, wave soldering component direction, etc.
2. Review the match between actual components and pads: whether the actual purchased SMT patch components match the designed pads (if inconsistent, use red marks to indicate), whether they meet the spacing requirements of the patch machine.
3. Generate three-dimensional graphics: Generate three-dimensional graphics, check whether the spatial components interfere with each other, whether the component layout is reasonable, whether it is conducive to heat dissipation, whether it is conducive to heat absorption of SMT reflow soldering, etc.
4. PCBA production line optimization: optimize the mounting sequence and material station position. Input the existing placement machines (such as Siemens high-speed machines and Universal multi-function machines) into the software, and allocate the existing board placement components, such as how many varieties and where the Siemens places them, how many varieties and where the Universal places them, and where the materials are picked up. This optimizes the SMT patch processing program and saves time. For multi-line production, the placement components can also be optimized.
5. Operation instructions: Automatically generate operation instructions for workers on the production line.
6. Inspection rule revision: The inspection rules can be modified. For example, if the component spacing is 0.1mm, it can be set to 0.2mm according to the specific machine model, manufacturer, and complexity of the board: the wire width is 6mi, which can be changed to 5mil for high-density design.
7. Support Panasonic, Fuji, and Universal patch software: It can automatically generate placement software to save programming time.
8. Automatically generate steel plate optimization graphics.
9. Automatically generate AOI and X-RAY programs.
10. Inspection.
11. Support various software formats (Japan, US KATENCE, China PROTEL).
12. Review the BOM table and modify the corresponding errors, such as manufacturer spelling errors, etc. And convert the BOM table into software format.
