Soldering Instructions

1. Insert header through PCB holes with proper orientation
2. Ensure header sits flush against PCB surface
3. Check pin 1 alignment with PCB markings
4. Solder all pins with appropriate temperature (300-350°C)
5. Use flux for clean, reliable solder joints
6. Inspect for cold solder joints or bridges
7. Clean flux residue if required

Mechanical Considerations

- Shroud provides mechanical protection and alignment
- Keying slot prevents incorrect mating
- Secure PCB mounting prevents connector stress
- Consider cable strain relief for permanent installations
