PCB is a widely used product, that can be used in all electronic and electrical equipment, such as mobile phone, computer, automobile, display screen, air conditioner, remote control and so on. Here are the basic rules for component wiring and layout in PCB board:
1. Arrange components in circuit modules based on function, keeping digital and analog circuits separate.
2. Do not install components, devices, or screws within 3.5mm (for M2.5) and 4mm (for M3) around non-mounting holes such as positioning and standard holes within 1.27mm.
3. Place components such as resistors, inductors, and electrolytic capacitors under the cloth hole to avoid short circuits with wave soldering holes and component shells.
4. Ensure components are at least 5mm away from the edge of the board.
5. Maintain a distance of more than 2mm between the outer side of mounting elements and adjacent inserting elements.

6. Keep metal shell components and metal parts separate from other components, printed lines, and pads by a spacing of greater than 2mm.
7. Avoid placing heating elements close to wires and thermal elements and evenly distribute high-heat devices.
8. Position power sockets around the board as much as possible and arrange wiring terminals of the power socket and the connected busbar on the same side.
9. For IC components, align them unilaterally, and ensure clear polarity marks for polar components. Avoid having more than two directions for polarity marks on the same board, and if there are two directions, they should be perpendicular to each other.
10. Maintain proper density for surface wiring, using mesh copper foil when the density difference is too large (grid greater than 8mil or 0.2mm).
11. Avoid through holes on patch pads to prevent loss of solder paste and virtual welding of components.
12. Align patch components unilaterally with consistent character and packaging direction.
13. Mark devices with polarity in the same direction on the same board.
These rules can serve as a reference for those new to PCB design. Keep in mind that single-layer board wiring is relatively simple, while multi-layer board design requires more exploration and learning for better design.
