As a novice in PCB board design, what introductory knowledge should you master?

As a novice in PCB board design, what introductory knowledge should you master? Answer:

1. Wiring direction: The layout direction of the components should be as consistent as possible with the schematic diagram. The wiring direction preferably coincides with that of the circuit diagram. It is often necessary to perform various parameters on the welding surface during the production process.

2. The arrangement of components should be reasonable and uniform, and strive to be neat and beautiful.

3. Placement of resistors and diodes: plane and vertical: (1) Flat release: When the number of circuit components is small and the size of the circuit board is large, it is usually flat. (2) Vertical: When the number of circuit components is large and the size of the circuit board is small, it is generally vertical, and the spacing between the two pads is generally 1 to 210 inches.

4. Place the potentiometer,
The principle of the IC seat: (1) Potentiometer: When designing the potentiometer, the current should be increased when the potentiometer is adjusted clockwise. The potentiometer should be placed in the structure of the whole machine and the layout requirements of the panel, as far as possible on the edge of the board, and the handle should be turned outward. (2) IC seat: In the case of using the IC seat, it is necessary to pay special attention to whether the direction of the positioning groove on the IC seat is correct, and whether the IC pins are correct.

5. Arrangement of incoming and outgoing terminals: (1) The relevant two lead terminals should not be too large, generally about 2 to 310 inches. (2) The entrance and exit should be concentrated on 1 to 2 sides as much as possible, and should not be too discrete.

6. When designing the wiring diagram, pay attention to the order of the pins and the spacing of the components should be reasonable.

7. Under the premise of ensuring the performance requirements of the circuit, the design should be reasonable, the external wiring should be used less, and the wires should be routed according to the requirements.

8. When designing the wiring diagram, minimize the wiring and try to make the lines concise and clear.

9. The width of the terminal strip and the spacing of the lines should be moderate. The spacing between the two pads of the capacitor should be as close as possible to the spacing of the capacitor leads.

10. The design should be carried out in a certain order, for example, from left to right, from top to bottom.
