PCB Design Guidelines for Optimal Manufacturing
Line Width and Spacing Considerations
- Minimum line width: 6 mil (0.153 mm)
- Minimum line spacing: 6 mil (0.153 mm)
- Line spacing for paired traces: 0.508 mm (20 mils)
Through-Holes Specifications
- Minimum hole diameter: 0.3 mm (12 mils)
VIA and Pad Guidelines
- Minimum VIA hole aperture: 0.3mm (12 mils)
- Minimum pad size: 6 mil (0.153 mm)
Hole Spacing and Design Considerations
- Hole spacing for VIA holes: at least 6 mil
- Hole spacing for PTH (Plated Through Hole): at least 0.45mm
- Insertion hole (PTH) pad size: at least 0.2mm
Additional Design Tips
- Place PCB shapes on the KEEPOUT or mechanical layer
- Ensure alignment between mechanical and KEEPOUT layers
- Use multiple pads for metalized slots or holes
