|
|
Assembly drawings and instructions for your KiCad project.
|
|
|
|
## Purpose
|
|
This directory contains assembly-related documentation and drawings that help with the physical construction of your PCB:
|
|
- Assembly drawings
|
|
- Component placement guides
|
|
- Assembly instructions
|
|
- Pick and place references
|
|
|
|
## File Types
|
|
- **`.pdf`**: Assembly drawings and instructions
|
|
- **`.png/.jpg`**: Assembly photos and diagrams
|
|
- **`.txt/.md`**: Text-based assembly instructions
|
|
- **`.csv`**: Component placement data
|
|
|
|
## Assembly Drawings from KiCad
|
|
1. Open your PCB (`.kicad_pcb`)
|
|
2. Go to **File → Plot**
|
|
3. Select layers for assembly:
|
|
- F.Fab (Front Fabrication)
|
|
- B.Fab (Back Fabrication)
|
|
- F.SilkS (Front Silkscreen)
|
|
- B.SilkS (Back Silkscreen)
|
|
4. Enable "Plot footprint values" and "Plot reference designators"
|
|
5. Set output directory and plot
|
|
|

## Assembly Drawing Guidelines
|
|
- Include component reference designators
|
|
- Show component values where helpful
|
|
- Indicate polarity for polarized components
|
|
- Mark pin 1 locations for ICs
|
|
- Include assembly notes and warnings
|
|
- Use different colors for different component types
|
|
|
|
## Assembly Instructions Content
|
|
- **Component list**: What components go where
|
|
- **Assembly order**: Sequence for efficient assembly
|
|
- **Special procedures**: Unique assembly steps
|
|
- **Soldering notes**: Temperature, time, flux requirements
|
|
- **Testing points**: Where to probe during assembly
|
|
- **Troubleshooting**: Common issues and solutions
|
|
|
|
## Pick and Place Data
|
|
Generate component placement data for automated assembly:
|
|
1. In KiCad PCB editor, go to **File → Fabrication Outputs → Component Placement**
|
|
2. Configure format (CSV recommended)
|
|
3. Include position, rotation, and side information
|
|
4. Save to this directory
|
|
|
|
## Quality Control
|
|
- **Assembly checklist**: Step-by-step verification
|
|
- **Visual inspection**: What to look for
|
|
- **Electrical testing**: Basic functionality tests
|
|
- **Rework procedures**: How to fix common mistakes
|
|
|
|
## Best Practices
|
|
- Create assembly drawings at 1:1 scale when possible
|
|
- Use clear, high-contrast colors
|
|
- Include revision information
|
|
- Document any special tools required
|
|
- Provide multiple views for complex assemblies
|
|
- Include photos of completed assembly
