1. Wiring direction: look from the surface of welding, the arrangement of components bearing as far as possible to keep consistent with schematic diagram, wiring direction should take line direction is consistent with the circuit diagram, because of the production process often need to test the various parameters on surface of the welding, so do check in for production, debug and repair (note: refers to the circuit performance and under the premise of the machine installation and panel layout requirements).
2. Each component arrangement, the distribution should be reasonable and even, strive for neat, beautiful, rigorous structure of the process requirements.
3. Resistors and diodes can be placed horizontally or vertically:
4. Potentiometer: IC seat placement principle
5. Layout of inlet and outlet terminals
6. When designing wiring diagram, it is necessary to pay attention to the sequence of pins and reasonable spacing of component pins.
7. On the premise of ensuring circuit performance requirements, the design should strive for reasonable wiring, less use of external crossover line, and in accordance with the requirements of certain charging line, and strive for intuitive, easy to install, height and maintenance.
8. When designing wiring diagram, go line as far as possible little turn, do one's best line is simple and clear.
9. The width and width of the wiring strip should be moderate and the distance between the two welding pads of the capacitor should be as close as possible to the distance between the lead pins of the capacitor.
10. The design should proceed in a certain sequential direction, such as from left to right and from top to bottom.
