Drawing circuit diagrams for double-sided circuit boards
There are now a variety of dedicated B-drawing software, such as r, etc., which can draw multi-layer (including double-sided) circuit board diagrams. The positions of the multiple layers are aligned. There are vias to connect the circuits between each layer to achieve cross-wiring and facilitate typesetting. After typesetting is completed, it can be handed over to a professional board manufacturer to form a circuit board for a specific circuit.
. The double-sided circuit board must be drawn into a circuit schematic diagram in two steps. The first step: first draw the symbols of the main components on the paper according to the position of the circuit board, arrange and draw the pin connections and peripheral components appropriately, and complete the sketch. Step 2: Analyze the principle and organize the circuit diagram according to the customary drawing method. You can also use circuit schematic software to arrange the components and connect them, and then use its automatic layout function to organize them.
The lines on both sides of the double-sided circuit board must be accurately aligned. You can use the two tips of tweezers to position, flashlight light transmission, multimeter to measure continuity and breakage, etc. to determine the connection and direction of the solder joints and lines. If necessary, Remove the components and observe the lines underneath them.
