Precision PCB Fabrication, High-Frequency PCB, High-Speed PCB, Standard PCB, Multilayer PCB and PCB Assembly.
The most reliable PCB & PCBA custom service factory.
After PCB design is completed, we need to carry out function check for all projects. Just as we do when we finish the test paper ourselves, do a simple analysis and go over all the questions again to make sure we don't make a big mistake because of negligence. Similarly, PCB design is the same. The following are the items to be checked after PCB design:
1. DFM audit of light board: whether the production of light board meets the process requirements of PCB manufacturing, including wire width, spacing, wiring, layout, hole passing, Mark, direction of wave soldering components, etc.
2. Check the consistency between actual components and pads: whether the actual SMT SMT components purchas
ed are consistent with the designed pads (if not, it will be marked in red), and whether it meets the spacing requirements of the SMT machine.
3. generate three-dimensional three-dimensional graphics: generate three-dimensional graphics, check whether space components interfere with each other, component layout is reasonable, is conducive to heat dissipation, is conducive to SMT reflow heat absorption and so on
4. Optimization of PCBA production line: optimization of mounting sequence and material station position. Input the existing pasting machine (such as Siemens high-speed machine, global multi-function machine) into the software, distribute the existing board pasting components, how many varieties Siemens pasting, which several positions, how many varieties of the world, which several positions, in which station channel to take materials, etc. To optimize SMT SMT processing procedures, save time. For multi-line production, it is also possible to optimize the allocation of mount components.
5. Operation instruction: automatically generate operation instruction for workers on the production line.
6. Revision of inspection rules: Inspection rules can be modified. If the component spacing is 0.1mm, it can be set to 0.2mm according to the complexity of the specific model, manufacturer and plate. The wire width can be 6mi, and the high density design can be changed to 5mil.
7. support Panasonic, Fuji, global patch software: can automatically generate paste software, save programming time.
8. automatically generate steel plate optimization graphics.
9. automatic generation of AOI, X-ray procedures.
10. Check.
11. support a variety of software formats (Japanese, American KATENCE, Chinese PROTEL).
12. Review BOM, correct corresponding errors, such as manufacturer spelling errors, etc. And convert the BOM into software format.
