Key Points for Effective PCB Board Design
- Design Direction: When designing a PCB board, it is crucial to establish a logical direction for components to prevent interference. Consider factors like input/output, AC/DC, signal strength, frequency, and voltage levels. Avoid circular layouts to maintain isolation.
- Grounding Points: Selecting the right grounding points is essential for a well-functioning PCB. Ensure a common ground and merge multiple ground wires to the main ground to minimize interference.
- Power Filter/Decoupling Capacitors: Place filtering and decoupling capacitors close to the components needing them to optimize performance and address grounding issues.
- Line Diameter and Hole Size: Pay attention to the size of lines and holes, especially for high-voltage and high-frequency applications. Wide ground wires with ample copper area enhance grounding effectiveness.
- Number of Vias, Solder Joints, and Line Density: Minimize vias to streamline production and prevent soldering issues. Control line density to avoid solder joint merging and ensure welding quality.
