Circuit diagram to PCB wiring diagram

Circuit diagram to PCB wiring diagram is as follows:

Definition of circuit diagram: connect the power supply, switch (key), electrical appliance, ammeter and voltmeter with wires to form a circuit, and then use unified symbols to represent it, and then draw the circuit diagram. A circuit diagram is a graphical representation of a physical diagram with symbols. Circuit diagram adopts circuit simulation software to carry out circuit aided design and virtual circuit experiment (for teaching), which can improve the work efficiency of engineers and save learning time.
