Board front line wiring
When manual wiring (non-model, mold wiring), it should meet the requirements of straight, neat, close to the laying surface, reasonable wiring and no loose joints for easy maintenance.
1. The routing channel should be as few as possible. The sinking wires in the same channel should be classified according to the main and control circuits. The single layer should be closely packed or bundled, and should be placed close to the laying surface.
2. The length of the wire should be as short as possible, and it can be horizontally spanned, such as the connection between the two component coils and the main contact of the wire. If there is a certain margin, the surface may not be applied.
3. The wires of the same plane should be consistent or consistent, and cannot be delivered*. When it is necessary to pay *, it can be horizontally spanned, but it must be reasonable.
4. The wiring should be horizontal and vertical, and the direction of the transformation should be 90° vertically.
5. If the upper and lower contacts are not under the same vertical line, they should not be connected by diagonal lines.
6. When connecting the wire to the terminal block or the wire pile, the insulation layer, the non-reverse ring and the exposed copper should not be more than 1mm. And the distance between the wires of different contacts of the same component and the same circuit is kept consistent.
7. There must be no more than two connecting wires on the terminals of an electrical component. Only one connecting wire on each terminal block is allowed to be connected.
8. When wiring, it is strictly forbidden to damage the core and wire insulation.
9. When the cross-sectional area of ​​the wire is different, this will place the cross-sectional area on the lower layer and the cross-sectional area on the upper layer.
10. When wiring multiple wires (main circuit), the whole vertical surface of the same horizontal plane or low-voltage electrical comprehensive tester should be achieved. 11. If the line is simple, the encoder sleeve can be omitted.
