Inspection method of flexible board wiring

After the soft board wiring design is completed, it is necessary to check whether the soft board wiring design meets the rules and whether the rules formulated do not meet the requirements of the soft board production process. How to check after soft board wiring? Today, I brought you the inspection method of soft board wiring. Let's have a look!

The items to be checked after the general soft board wiring include: general soft board design drawing inspection items, soft board physical properties inspection items, soft board installation requirements, soft board electrical properties inspection items, soft board mechanical design factors, soft board pull-out requirements, soft board electrical precautions, soft board mechanical precautions, soft board wiring path and positioning, soft board wire spacing, soft board width and thickness List of inspection items for flexible board wire drawing and flexible board design items.

1. Check whether the distance between through holes is reasonable.

2. Check whether the width of power line and ground wire is appropriate.

3. Check whether the key signal lines have taken the best measures.

4. Check whether analog circuit and digital circuit have independent grounding wires.

5. Check whether the graphics added to the softboard will cause short circuit of the signal.

6. Check whether there is a process line on the soft board.

7. Check whether the outer frame edge of the power layer in the multi-layer flexible board is shrunk.
