Basic Principles of Printed Circuit Board (2)

Basic Principles of Printed Circuit Board:

5. Arrangement of In and Out Terminals

(1) The distance between the two associated lead ends should not be too large, generally about 2 to 3/10 inches is more appropriate.

(2) The inlet and outlet ends should be concentrated on one or two sides as much as possible, and should not be too discrete.

6. Pay attention to the pin arrangement sequence when designing the wiring diagram, and the component pin spacing should be reasonable.

7. Under the premise of ensuring the performance requirements of the circuit, the design should strive for reasonable wiring, less use of external jumpers, and wiring according to certain requirements for smooth charging, and strive to be intuitive, easy to install, height and overhaul.

8. When designing the wiring diagram, the wiring should be as few as possible, and the lines should be simple and clear.

9. The width of the wiring strip and the line spacing should be moderate, and the spacing between the two pads of the capacitor should be as consistent as possible with the spacing of the capacitor lead pins.

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