The wiring principle: The knowledge of wiring is very advanced, It has some general principles

1.The wiring of high frequency PCB should be thinner and shorter.

2.Attention should be paid to isolation between large current signal, high voltage signal and small signal,the isolation distance is related to the degree of pressure，in general, the distance between the plates should be 2mm at 2kV，on top of that, the ratio is even larger,for example, to withstand a voltage test of 3 kV,the distance between the high and low voltage lines should be more than 3.5mm, in many cases, in order to avoid leakage, printed circuit boards are also slotted between high and low voltage；

3. When wiring two panels, the wires on both sides should be perpendicular to each other, oblique, or bent，avoid parallel to each other to reduce parasitic coupling; Printed wires used as input and output circuits should be kept as far as possible from being parallel to each other. to avoid a feedback, it is better to put a ground wire between these wires;

4. The wiring corner should be greater than 90 degrees as far as possible. Also, try not to use 90-degree corners.

5. Both address wire and data wire, the wire length should not be too  difference , otherwise, the short wiree part should be compensated by artificial bending line;

6. Wiring should be on the welding surface as far as possible, especially regular PCB;

7. Minimize the use of holes and wire jumper;

8. Single panel pads must be large enough, the wires connected to the pads must be thick enough, the general quality of single panel manufacturers will not be very good, otherwise there will be problems with welding and re-work.

9. Large area copper should be used in grid, in order to prevent the wave welding board to produce air bubbles and bending due to thermal stress, but in special cases you have to think about the direction and the size of GND, you can't just fill it with copper foil ,it needs to be wired.

10. Components and and wiring should not be placed too close to the side,the general single panel is mostly made of paper, it is easy to break under stress, it will be affected if you wire or place components at the edge.
11. Convenience of production, commissioning and maintenance must be considered.
