PCB News - Talking about PCB Design Review

A. Review process After the design is completed, the PCB designer or product hardware developer can propose a review of the PCB design quality according to the needs. For the work process and review method, please refer to the "PCB Design Review Specification".

B. Self-check items

If you do not need to organize a review team to conduct a design review, you can check the following items yourself.
1. Check the high-frequency, high-speed, clock and other fragile signal lines, whether the loop area is the smallest, whether it is far away from the interference source, whether there are redundant vias and windings, whether there is a subdivision area of the strata
2. Check whether there are signal wires passing under the crystal, transformer, optical lotus, and power module. Try to avoid threading under them, especially the grounded copper sheet should be laid under the crystal as much as possible.
3. Check whether the positioning holes and positioning parts are consistent with the structure drawing, and whether the ICT positioning holes and SMT positioning cursors are added and meet the process requirements.
4. Check whether the serial number of the device is placed according to the principle of left to right, and there is no silk screen covering the pad; check whether the version number of the silk screen complies with the version upgrade specification and mark it.
5. Report whether the wiring is 100% complete; whether there is a cable head; whether there is an isolated copper sheet.
6. Check that the power supply and ground are divided correctly; the single-point common ground has been processed;
7. Check that the light drawing options of each layer are correct, and the markings and light drawing names are correct; only the drawing markings of the drilling layer are needed to join the PCB board.

8. Output the gerber file, use CAM350 to check and confirm that the gerber file is generated correctly.
9. Fill in the PCB design(file) self-inspection form as required, and submit it to the process designer for process review together with the design documents.
10. Actively improve the problems found in the process review to ensure the machinability, manufacturability and testability of the veneer.

The above is the introduction of PCB design review. Ipcb is also provided to PCB manufacturers and PCB manufacturing technology.
