PCB double layer board wiring skills

1. Clearance clearance is minimum 10mil

2. It is best to use double-hole parallel mode for the holes of the main power cable

3. If there are multiple RF circuits, in order to reduce interference, the RF can be crossed on different layers.

4. Wiring with warp and weft wiring, clear wiring of upper and lower layers

5. Do not lay copper under the network chip

In order to prevent scratches, the four corners of the board had better be rounded
