⚠️ Notes
- Ensure proper PCB layout to match the 4.20mm pin pitch to avoid misalignment during assembly.
- Use proper soldering temperatures to prevent LCP housing deformation during reflow soldering.
- Keep the gold-plated contact area clean and free from contamination or oxidation.
- Verify contact resistance and insulation resistance meet application specifications.
- Avoid excessive mechanical force during mating and unmating to preserve terminal integrity.
- Store connectors in dry, anti-static packaging until use to avoid damage.
- Maintain ESD protection throughout the assembly process to avoid electrostatic discharge damage.
