1. There are now various specialized PCB drawing software, such as Protel, which can draw multi-layer (including double-sided) circuit board diagrams. The layers are aligned in orientation and have vias to connect the circuits between them, completing the insertion and wiring, and facilitating layout. After the typesetting is completed, it can be handed over to a specialized board manufacturer to produce circuit boards for specific circuits.

2. A double-sided circuit board needs to be drawn in reverse to create a circuit schematic, which can be divided into two steps. Firstly, draw the symbols of the primary components such as ICs on paper according to the orientation of the circuit board, arrange the wiring of each pin and peripheral components appropriately, and draw the sketch to complete. Then: Analyze the principle and tidy up the circuit diagram according to the customary drawing method. It is also possible to use circuit schematic software to connect components after arranging them, and then use its active layout function to tidy up.

The lines on both sides of the dual panel should be accurately aligned, and methods such as positioning with the two tips of tweezers, photoelectric transmission, and measuring continuity with a multimeter can be used to confirm the connection and direction of the solder joints and lines. If necessary, components should be removed to observe the direction of the lines below.
