The items that need to be checked after general PCB wiring include: general PCB design drawing inspection items, PCB physical characteristics inspection items, PCB installation requirements, PCB electrical characteristics inspection items, PCB mechanical design factors, PCB pull-out requirements, PCB electrical precautions, PCB mechanical Precautions, PCB routing routing and positioning, PCB conductor spacing, PCB width and thickness, PCB conductor pattern inspection and PCB design item inspection item list.
1. Check whether the distance between the through holes is reasonable.
2. Check whether the width of the power line and ground line is appropriate.
3. Check whether the critical signal line has taken the best measures.
4. Check whether the analo circuit and the digital circuit have independent ground wires.
5. Check whether the graphics added in the PCB will cause a short circuit of the signal.
6. Check whether there is a process line on the PCB.
7. Check whether the outer frame edge of the power layer in the multilayer PCB board is shrunk.
