1. Clear and readable text: Ensure that the text on the silk screen is clear and readable, choose appropriate fonts and text sizes for easy recognition during manufacturing and use.
2. Component identification: Indicate the name, model, and value of the component in silk screen printing for easy maintenance and repair. Ensure that the location of the identification does not obstruct the components or affect welding.
3. Pin marking: Mark the pin number around the pins of the component for easy soldering and debugging. Use clear pin markings, such as numbers or letters.
4. Direction indication: Indicate the direction of the PCB, usually indicated by arrows or other directional symbols. This is crucial for ensuring the correct orientation during assembly and use.
5. Layer marking: Mark the corresponding layer information on the top and bottom layers of the PCB for accurate identification during manufacturing and maintenance.
6. Specify graphics and lines: Maintain the clarity of graphics and lines, avoid overly complex silk screen designs, and avoid affecting production quality.
7. Appropriate spacing: The spacing between silk screen printing and components, solder pads, etc. should be sufficient to avoid affecting welding and assembly processes.
8. Material selection: Choose corrosion-resistant and wear-resistant screen printing materials to ensure that the screen printing remains clear and visible throughout the lifespan of the PCB.
