In addition, in electronic products with both analog and digital circuits, the printed boards often separate their ground lines to form an independent grounding grid, which can also be used as a basis for identification and judgment. When the factory is wiring the printed circuit board, in order to prevent self-excitation and anti-interference, the ground copper foil is generally set to the widest ( high-frequency circuits often have large-area grounded copper foil), the power supply copper foil is second, and the signal copper is used. Included with a Fusion 360 for personal use subscription, EAGLE free download is a limited version for hobbyists including 2 schematic sheets, 2 signal layers, and an 80cm2 (12.4in2) board area. The power and ground lines can also be found from the three-terminal regulator pins. Taking the power supply circuit as an example, the negative terminal of the rectifier connected to the secondary of the power transformer is the positive pole of the power supply, and a large-capacity filter capacitor is generally connected between the ground and the ground, and the capacitor casing has a polarity mark. Correctly distinguish the ground, power and signal lines of the printed board. DipTrace is an advanced PCB design software application that consists of 4 modules: PCB Layout with shape-based autorouter, high-speed/differential signal routing tools, and 3D PCB Preview/Export, Schematic Capture, and Component/Pattern Editors that allow you to design custom component/footprint libraries.
