1. PCB Layout 1. Follow the layout principle of “big first, small later, difficult first, easy later”, meaning that important unit circuits and core components should be prioritized in the layout. 2. The layout must refer to the schematic diagram and place components according to the signal flow rules of the schematic. 3. The arrangement … Read more
Click on the above “Mechanical and Electronic Engineering Technology” to follow us 3D printing technology is revolutionizing the way we manufacture circuit boards. The traditional PCB manufacturing process involves multiple steps such as etching, drilling, and laminating, while 3D printing offers a more direct method. With 3D printing, designers can print circuit boards directly from … Read more
The Printed Circuit Board (PCB), known as the “mother of electronic products”, is required in all electronic devices or products. The development level of its industry can reflect the development speed and technological level of the electronic information industry in a certain country or region. PCBs are mainly composed of two types of materials: insulating … Read more
01 Power Layout and Wiring Digital circuits often require non-continuous current, which can cause surge currents in some high-speed devices. If the power routing is long, the surge current can lead to high-frequency noise, which can then couple into other signals. In high-speed circuits, parasitic inductance, parasitic resistance, and parasitic capacitance are inevitable, so this … Read more
