PCB (printed circuit board) design is to arrange electronic components (such as resistors, capacitors, integrated circuits, etc.) on the circuit board according to the circuit connection relationship, and design reasonable circuit connections to realize the functions of electronic products. The following is a detailed introduction about PCB design:
I. Design principle
Connectivity principle: ensure that all components in the circuit are connected correctly according to the connection mode of the circuit diagram to form a complete circuit.
Electromagnetic compatibility principle: consider electromagnetic compatibility when designing circuit board layout and circuit, reduce the interference between circuits, and ensure the stable operation of products.
Heat dissipation principle: reasonably design PCB layout to ensure effective heat dissipation of heat dissipation components (such as heat sinks and radiators) and prevent overheating of components from affecting performance.
Reliability principle: when designing PCB, consider the safe distance of components and the reliability of wiring to ensure the long-term stable operation of PCB.
